cave, erect, very hairy outside: lower lip spreading, scarcely 
longer, trifid ; the middle segment hardly broader than the lateral

Abyssinian Lasiocorys.. Shrub. 
Cult, A light rich soil will suit the species of this genus; 
and cuttings will strike root readily in the same kind of earth, 
with a hand-glass placed over them ; but if seeds ripen, this will 
be unnecessary. 
LXXXIX. RO'YLEA (named in honour of John Forbes 
Royle, M.D. surgeon in the East India Company's Service;

mate by pairs, 2-celled : cells divaricate, at length sub-confluent. 
Style almost equally bifid at top; lobes subulate, stigmatiferous 
at apex. Achenia dry, obtuse at apex.—Allied to Bailóla and

the base, 10-nerved ; limb sub-bilabiately and membranaceously 
prolonged : upper lip short, entire, or triangular: lower lip

calyx ; and from the latter genus in the divisions of the style.
