180 ENGLISH BOTANY. 



stem usually shorter and more equal in size than in H. glabra, but I 

 can see no difference as to the clusters being separate or distinct, which 

 Pi-ofessor Babington makes one of the distinguishing characters. In 

 cultivated specimens, from a root received from the Cambridge garden 

 by Mr. H. C. Watson as H. ciliata, the clusters are perfectly confluent on 

 the lateral branches. On the wild Cornish plant they are sometimes 

 confluent, sometimes distinct, in the latter case with fewer flowers thnn 

 in the former; but th€ real distinction between H. glabra and H. ciliata 

 lies in the suff"rutescent growth of the latter, in which, as well as in the 

 broad leaves and stem being pubescent only on the side away from the 

 ground, it resembles H. latifolia, Laperyoitse, though the latter plant 

 differs in the more distinctly stalked and larger flowers, bristly-hairy 

 sepals, and erect stigmas.

GENUS III.— I LLECEBRUM. Linn. 



Calyx coloured, parchment-like, persistent, 5-partite; in fruit seg- 

 ments keeled, pure white, oblong, thickened and slightly hooded at the 

 apex, where they are produced into a subulate point. Petals ( ?) 5, 

 perigynous, resembling barren filaments. Stamens 5. Ovary 1-celled, 

 containing a Snigle ovule ; stigmas 2, subsessile. Fruit ovoid, mem- 

 branous, opening at the base by 5 or 10 valves, which remain attached 

 at the base, enclosed in the connivent calyx segments, which enlarge 

 and become corky after flowering. 



A glabi'ous herb with filiform procumbent stems, and broadly ovate 

 opposite leaves, with minute scarious stipules. Flowers minute, sessile, 

 aiTprrcKated in the axils of the leaves along the whole of the stem and 

 branches. 



The origin of the name of this genus of plants is from Illccebra, an enticement, as 

 enticing the simpler into marshes and bogs.
