 Tralee to Dingle, Ireland. Mr. J. T. Mackay. 



Perennial. July, August. 



Roots fibrous, certainly perennial, propagating themselves widely, 

 for many years, among short wet grass, in the garden of the late 

 Mr. Vere at Kensington Gore. Stems prostrate, creeping ex- 

 tensively, branched, entangled, leafy, slender and delicate, mi- 

 nutely hairy like the rest of the herbage. Leaves stalked, hori- 

 zontal, orbicular-kidney-shaped, bluntly crenate, rather succu- 

 lent, veiny, light green ; paler beneath. Fl. on short, axillary, 

 simple stalks, whitish ; their 3 upper segments more or less 

 tinged with pale red. 

 This genus, named by Linnaeus in honour of Dr. Humphrey Sib- 

 thorp, the successor of Dillenius in the botanical chair at Ox- 

 ford, was most richly deserved by his son, the late Professor, au- 

 thor of the Flora Oxoniensis, and the collector of abundant ma- 

 terials for the Flora Graca, which he never lived to describe. 

 Of the latter splendid work 5 volumes in folio, each containing 

 100 coloured plates, have already appeared, and the rest are in 

 progress.
