144 DIDYNAMIA— ANGIOSPERMIA. Limosella. 



Cornwall Pennywort. Petiv. H. Brit. t. 6./. 11. 



In moist shady places, about springs and rivulets, in the south. 



Plentiful in Cornwall and Devonshire. Ray, and Prof. J. Sib- 

 thorp, M.D. Near the bottom of Conner hill, on the road from 

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



Perennial. Jtdy, 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 j paler beneath. Fl. on short, axillary, 

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

 tinged with pale red. 



This genus, named by Linnaus 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 Grceca, which he never lived to describe. 

 Of the latter splendid work 4 volumes in folio, each containing 

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

 progress.

Cal. turbinate ; border in 5 deep, lanceolate, acute, upright, 

 nearly equal segments. Cor. somewhat bell-shaped ; tube 

 cylindrical, the length of the calyx ; limb in 5 deep, ovate, 

 spreading, slightly unequal segments, the 2 uppermost 

 concave, lower one smallest. Filam. from the mouth of 

 the tube, awl-shaped, almost equal, shorter than the limb, 

 sheltered by its 2 upper segments, but spreading slightly 

 laterall}', and converging in pairs. A^ith. roundish, of 

 2 lobes. Germ, ovate. Style tapering, short. Stigma 

 capitate, globose, cloven. Caps, ovate, of 2 cells, and 2 

 valves, the partitions narrow, from the inflexed margins 

 of the valves. Seeds numerous, oblong, furrowed, trans-

The partitions, at first connected with the receptacle, sepa-
