nane road: R.W.S. 1890, and in 1905; on the east side of 
Ballaghbeama Gap, 1906.—III. Abundant on damp roadside 
rocks and in the adjoining wood at Glanleam, Valencia, 
1892-1911.—IV. In a gully above Lough Reagh, 1889, and 
above Lough Eskabehy, Glencar, 1911—V. Near Kilteen- 
bawn south of Camp, Tralee Bay, 1890 ; in several places 
about the north side of Connor Hill and Brandon Mountain, 
1890-1908 : R.W.S.—VI. In a sheltered place below Tore 
Waterfall, Killarney: Mackay Cat. 1825—still in two or 
three places about the waterfall and Tore Mountain, 1888- 
1914: BR.W.S. 
While Linné himself restricted S. Geum to plants with 
kidney-shaped leaves, later writers have included under his 
name forms with orbicular leaves. These latter, which can 
only be included under 8. Gewm (sensu lato), are much more 
common in Kerry than those with pronounced reniform 
leaves and include a greater variety in their shape. Thus 
they may have bases either cordate, entirely devoid of sinus 
or even tapering slightly into their footstalk, and while 
nearly all these may be found with acute or with blunt 
teeth, forms with the latter are much the rarer of the two 
in 8. Geum (sensu lato). Examples of many of these forms 
are shown on Pl. II.* 
Several of these round-leaved forms have been given 
names and described as distinct varieties or species, such as 
S. elegans and S. gracilis by Mackay, and S. polita by 
Haworth. They differ from each other chiefly in the colour 
or hairiness of their leaves and in the spots on their petals. 
The best known of these, and the only one that need be 
referred to here, is S. elegans. This plant was found by 
Mackay on Torc Mountain, where it still exists, and is 
described in his ‘‘ Catalogue of the Plants found in Ireland,” 
1825. Two leaves of S. elegans are shown on PI. IL., figs. 
23 & 24, taken from specimens gathered and named by 
Mackay himself. The plant figured is seen to have a small 
orbicular leaf which passes rather abruptly into a short petiole. 
While often regarded as a distinct species, S. elegans is really 
but one of the many hybrid forms which are found only 
where S. Geum and S. umbrosa grow together, as about Tore 
* Puate II. (} life-size)—S. Gewm Auct. (Sensu lato—i.e. With round 
or roundish leaves) — 
Cordate base, crenate teeth. figs. 14. 
Cordate base, serrate teeth, figs. 5-13. 
Forms with non-cordate base, merging into 8. elegans and 8. hirsuta 
(sensu lato). figs. 14-34.
