20 DR. HOOKER ON THE VEGETATION 
scure ciliate. Perianthium 1" long. obscure et obtuse angulatum, 
lobis breviusculis glaberrimis v. margine obscure ciliatis. Filamenta 
ori inserta, antheris duplo longiora. i. 
Very nearly allied indeed to T. Madagascarense, A. DC., which is the only 
other species of this vast genus in which the bracteole exceed the braets, 
and the stems are almost leafless. It differs remarkably from that plant in 
size, in the very numerous very slender stems and branches, and much 
smaller flowers.

Arbor 15-20-pedalis, floribus viridibus.— P. Africane, Harv., simillima, 
differt ramis gracilibus foliis magis membranaceis, floribus duplo mi-

The only congener of this is a subtropical Port Natal tree.

Herba 6-8 pedalis. 
The bracts are decidedly ovate, though narrower than usual in this form 
which seems to pass into P. debilis, Forst.; it is described by Weddell as 
a Mediterranean and North African species. 
EUPHORBIACER. 
1. EvpHorsia (EsULA) AMPLA, H.f. Herbacea, glaberrima, foliosa ; 
caule simplici superne patentim ramoso, foliis membranaceis petiolatis 
lanceolatis acutis subtus glaucescentibus, floralibus late ovato-cordatis 
v. triangulari-ovatis acuminatis, involucris solitariis laminis fimbriatis, 
glandulis semilinearibus cornubus brevibus. 
Hab. In Clarence Peak, alt. 8500 ped. (fl. Dec.) 
Herba 4-pedalis, caule crassiusculo, terete, inferne nudo. Rami patentes, 
conferti, spithamei et ultra, foliosi, terminalibus divaricatis. Folia4"—5" 
long. i^-l" lat., integerrima, tenuiter nervosa, nervis divaricatis. 
Involucra sparsa, minima, solitaria. Stamina sub 8. 
The habit of this species resembles E. Lathyris, but the whole plant is 
of a totally different texture; it is most near E. monticola, Hochst., of 
Abyssinia, but has not the involucral glands produced into subulate 
horns as in that plant. It is also allied to the Indian E. Rothiana ; but 
in that the inflorescence is borne on peduncled special branches, and the 
involucres are numerous.
