Extract from Irish Botanical News, March, 2007:
"2006 has proved an extremely busy and very productive year botanically. The
highlight of the year was Dr Tom Gittings’ inadvertent and fortuitous
collection of Puccinellia fasciculata (Borrer’s Saltmarsh-grass) from the
margin of Commoge Tidal Lagoon (H4, W63.49) near Kinsale, in July – a
reinstatement to this site and to the Cork flora after a gap of some 40 years!
Equally satisfying, however, was the discovery that the Mibora minima (Early
Sand-grass) population in its only present-known Irish site at Cannawee
Dunes, Barley Cove, West Cork (H3, V76.25), consists of over 100,000
individual plants. An account is provided of the Co. Cork BSBI (Irish Branch)
Field Meeting of the 10-11 June, as are updates for many city and county
populations of both Veronica polita (Grey Field-speedwell) and Veronica
crista-galli (Crested Field-speedwell). Moreover, new adventive populations
of Erodium moschatum (Musk Stork’s-bill) and Geranium pusillum (Smallflowered
Crane’s-bill) are being discovered about Cork City with increasing
frequency since 2000 and, far from being transient, such populations are
tenaciously establishing themselves! Lastly, a brief account of ongoing Rosa
recording work in Co. Cork is given.
On 29 March, a survey of the roadside flora of the ‘back’ Cork Airport road
from Liss Crossroads (H4, W66.64) southwards to Fivemilebridge, showed
naturalized Veronica crista-galli (Crested Field-speedwell) populations to still
be locally common here, where I first recorded this species in the 1970s.
About this crossroads occurred small populations of Fumaria bastardii (Tall
Ramping-fumitory), Allium ursinum (Ramsons) and Lamiastrum galeobdolon
subsp. argentatum (Yellow Archangel). Later work from Crossnacroha Tjunction
(H4, W64.66) to Knockalisheen valley-bridge produced further stands
of Veronica crista-galli, associated with Veronica hederifolia subsp.
hederifolia (Ivy-leaved Speedwell), while the stream-valley itself held dense
35
populations of cohabiting Ranunculus ficaria subsp. bulbilifer (Bulbiliferous
Lesser Celandine) and R. ficaria subsp. ficaria (Lesser Celandine), together
with equal quantities of Hyacinthoides non-scripta (Bluebell) and Luzula
sylvatica (Great Wood-rush). Carex remota (Remote Sedge) occurred
commonly in damp ground, while occasional clumps of Carex laevigata
(Smooth-stalked Sedge) were also present.
On 3 April, putative leaf-rosettes of the nationally rare annual, Geranium
pusillum (Small-flowered Crane’s-bill) were found on a green in Glenthorn
Estate (H5, W68.74), Dublin Hill, Cork City. The determination was
confirmed later in the year, when both flowering and fruiting material became
available. [Note: The initial tentative G. pusillum determination was based
solely on leaf-petiole indumentum characters, which in this species consist of
minute, subequal, subretrorse, eglandular hairs that appear to the naked eye as
a very fine ‘down’, and which, in my experience to date, are absolutely
diagnostic for G. pusillum.] Within the same week, a naturalized stand of
Erodium moschatum (Musk Stork’s-bill) was found on a green-margin at the
junction of Dublin Hill and Delaney Park cul-de-sac (H5, W67.73), cohabiting
with a flowering population of Veronica polita (Grey Field-speedwell).
On 6 April, work on the Douglas Road allowed dinnertime botanizing in the
immediate area. Among the refinds were: Veronica polita (Grey Fieldspeedwell)
populations at the junction of Douglas Road/Eglantine Park (H4,
W69.70) and also at Endsleigh Park in the same 1-km square; a tiny, relict
population of Orobanche hederae (Ivy Broomrape) in a railed front garden
adjacent to the Briar Rose Hotel, and an equally relict population of Geranium
rotundifolium (Round-leaved Crane’s-bill) on a limestone wall on the
Rhodaville/Rathmore Road. Some tiny, precariously existing populations of
Geranium purpureum (Little-Robin) were also rechecked nearby, where I
originally recorded them in 1974. Most Cork City populations of both
Geranium purpureum and G. rotundifolium are now very small and disjunct,
as major infrastructural developments about the city since the late 1970s have
largely eliminated their habitats. On 7 April, cohabiting stands of Veronica
crista-galli and Valerianella carinata (Keeled-fruited Cornsalad) were reseen
about a limestone wall in Beaumont Avenue (H4, W70.71), Cork City, while
both Anemone nemorosa (Wood Anemone) and Allium triquetrum (Threecornered
Garlic) were seen on the green flanking Beaumont limestone quarry,
which latter habitat still holds tiny populations of Geranium purpureum
(Little-Robin), Linum bienne (Pale Flax), Orobanche minor (Common
36
Broomrape), Trisetum flavescens (Yellow Oat-grass) and Helictotrichon
pubescens (Downy Oat-grass), etc.
On 14 April, I revisited my Mibora minima (Early Sand-grass) site at
Cannawee Dunes (H3, V76.25), Barley Cove, West Cork. I was accompanied
by Michael Troy, who wished to photograph this nationally rare grass species.
Thankfully, the weather proved dry and sunny, and the grass was in full
flower. To my delight, I extended the known range of M. minima by some 200
m, and we conservatively estimated its metapopulation size at some 100,000
individual clumps. Mibora minima was most conspicuous on sloping sandblowouts,
but absent from adjacent sites where moss carpets dominated.
[Note: At anthesis, M. minima’s very long, straight filaments are well-exserted
from the florets, while the basifixed anthers are held in the same plane as the
filaments. However, the spent stamens become pendulous and droop over the
sides of the spikelets.]
On the journey home, a brief stop at Rock Island Bridge (H3, V81.26) showed
the seawall to still hold an abundance of Erodium moschatum (Musk Stork’sbill)
together with tiny populations of Erodium maritimum (Sea Stork’s-bill).
Sadly, the tiny quarry nearby had been reworked, resulting in the loss of
Cicendia filiformis (Yellow Centaury) that was first recorded here in 1993. On
the present visit, the sloping rocky outcrops adjacent to the western turret on
Rocky Island (same 1-km square) produced only a few flowering plants of
Orchis morio (Green-winged Orchid), associated with scattered leaf-rosettes of
Tuberaria guttata (Spotted Rock-rose).
On 24 April, relict Cork City populations of Geranium rotundifolium (Roundleaved
Crane’s-bill) and Allium vineale (Wild Onion) were rechecked in their
sites at Lough Villas and Croghtamore Gardens (H4, W66.70), while the
western pathway margin and laneways bordering the adjacent Cork Lough
itself, still held populations of Veronica crista-galli (Crested Field-speedwell)
(known since 1980), Veronica polita (Grey Field-speedwell) and Vulpia
myuros (Rat’s-tail Fescue).
On 13 May, a late-evening visit to picturesque Tibbotstown Reservoir (H5,
W81.76) near Carrigtwohill, produced a few flowering clumps of Primula
veris (Cowslip) in scrubwood on its eastern shore (an addition to the flora of
this site), while the sheer, southern wall of the Reservoir is bedecked with a
Parthenocissus species (Virginia-creeper). Although I have made sporadic
37
visits to Tibbotstown Reservoir since the 1970s, I have yet to make a thorough
inventory of its flora, which includes: Euphorbia hyberna (Irish Spurge),
Equisetum sylvaticum (Wood Horsetail), Carex hirta (Hairy Sedge), Mentha ×
verticillata (Whorled Mint), Apium inundatum (Lesser Marshwort), Littorella
uniflora (Shoreweed) and Salix purpurea (Purple Willow).
On 28 May, examination of the hedgebank on the southeastern branch of
Pounds Crossroads (H4, W58.73) near Cloghroe on the R579, produced an
abundance of flowering Geranium lucidum (Shining Crane’s-bill), associated
with scattered populations of Pimpinella major (Greater Burnet-saxifrage),
Ranunculus ficaria subsp. bulbilifer (Bulbiliferous Lesser Celandine),
Euonymus europaeus (Spindle), Hyacinthoides non-scripta (Bluebell), Allium
triquetrum (Three-cornered Garlic), Rosa arvensis (Field Rose), R. canina s.
st. (Dog-rose), R. corymbifera (Hairy Dog-rose), R. micrantha (Smallflowered
Sweet-briar), and the interspecific hybrids, Rosa × bigeneris (Hybrid
Sweet-briar) and R. sherardii (Sherard’s Downy-rose) × R. rubiginosa (Sweetbriar).
[Note: The identity of both Rosa hybrids was confirmed on 27 August
2006.] Moreover, the eastern branch of the crossroads held plenty of Carex
divulsa subsp. divulsa (Grey Sedge) on the roadside margins, a small
hedgebank population of Convolvulus arvensis (Field Bindweed) on a roadside
bend, and a naturalized stand of Persicaria campanulata (Lesser Knotweed)
bordering a roadside stream, this latter species being new to hectad W5.7.
Large, long-established stands of Veronica crista-galli (Crested Fieldspeedwell)
bordered both sides of the roadway, close to its junction with the
Cloghroe Road (the R579), which latter holds a stand of naturalized
Lamiastrum galeobdolon subsp. argentatum (Yellow Archangel), while nearby
Healy’s Bridge (H4, W60.73) produced a tiny population of Valerianella
locusta (Common Cornsalad) on its western parapet – an extremely localized
species about Cork City, despite the abundance of apparently suitable habitats
for it.
On 7 June, populations of Veronica crista-galli (Crested Field-speedwell)
were rechecked in the Amenity Park on the left bank of the River Sullane,
immediately below Macroom Town bridge (H3, W33.73). Carex divulsa
subsp. divulsa (Grey Sedge) was still common here, but C. muricata subsp.
lamprocarpa (Small-fruited Prickly-sedge) was not seen on this visit. The
stream at the northern end of the Park (which discharges into the R. Sullane)
still held a small population of Geum rivale (Water Avens), its lovely,
pendulous, salmon-pink flowers now being evident. Upriver of Macroom
38
Bridge, beds of Nuphar lutea (Yellow Water-lily) occur, while Geum rivale
(Water Avens) is of locally frequent occurrence on the left bank of the river.
[Note: Both Nuphar lutea and Nymphaea alba (White Water-lily) are
considerably under-recorded in Co. Cork. The same applies to many smaller
aquatic genera and species – a situation that is partly attributable to my
aversion for collecting aquatic material in general.] Walls about Macroom
Town held populations of Vulpia myuros (Rat’s-tail Fescue), while flowerbeds
within the castle grounds yielded Fumaria bastardii (Tall Ramping-fumitory),
F. muralis (Common Ramping-fumitory) and Veronica polita (Grey Fieldspeedwell)."![]()
