It will be noted that of 12 species occurring in Ireland, no less than 

 six are on record from one division only. This suggests that further work 

 on the group is still wanted in Ireland.

NOTES. 



BOTANY. 

 A Note on some Howth CloverSo 



On August 2ist I found Tyifoliiim filifornic L. in short grass on a rocky 

 knoll or ridge to the north of the Red Rock on the south side of Howth. 

 It was then, after an exceptionally cold and wet summer, in flower and 

 fruit, and numerous seedlings were showing among the old plants. The 

 station may, I think, be justly described as " wild ground." It occurred 

 also in at least two other places, about 150 and 400 yards to the west, on 

 grass beside the old cart-road leading to Sutton House ; the cart-road is 

 grass-grown and merges into pasture fields on each side. As neither Mr. 

 Hart nor ]\Ir. Colgan recorded the plant from HoAvth, the assumption that 

 it is native here might be received with some scepticism, but the locality 

 and the presence of other clovers not unusually associated with it certainly 

 tend to warrant its claim to native status. 



Oynithopiis perpusillus L. grows with T. filifoinne in the first station 

 mentioned ; it occurs in plenty at intervals along the ridge, on both sides 

 of the boundary walk of ]Mrs. Bellingliam's farm, and also about one 

 quarter mile to the west on similar ground, where it is associated witli 

 T. striatum. The old records in " Cybele Hibernica " for Ornithopus at 

 Sutton probably refer to the stations mentioned above ; Mr. Colgan's 

 own record is confined to " a rocky knoll," and Mr. Hart does not mention 

 the locality at all, though he records it in three other places, where I have 

 not yet seen it. If it is " much rarer now [1904] than it was in INIackay's 

 time," as suggested by ]\Ir. Colgan, the probable explanation is that some 

 of its old stations have been destroyed by building or cultivation. Orni- 

 thopus was in flower and fruit in August, but the only piece of T. striatu})i 

 that I saw was one withered stem ; this occurred in the station recorded in 

 " Cybele " by Miss R. Mahaffy. The same place is remarkable for the 

 abundance of a practically white form of Geranium molle ; Erodium 

 moschatum is also there. 



On August 2ist Trigonella ornithopodioides DC. was found in flower and 

 in abundance on the road leading to the Bailey Lighthouse and in short
