Plant 3-t) in. Iiigh, bushily much braucLecI ; 

 branches alternate and opposite on the 

 same plant; involucre 1-1 J lin. in 

 Lliam., glabrous outside (and see 65, E, 

 stapelioides) (61) gentilis. 



tfLeaveSj leaf -scars and branches (except by abortion) 



all oi»posite ; leaves rudimentary or very small, 

 §-lJ lin. long : 



Glands at the base of the rudimentary leaves or at 

 the sides of the leaf-scars large and very con- 

 spicuous, subglobosCj persistent : 



Ultiiaate Howering branches (dried) 1 lin. thick ; 

 involucres sessile or in small subsessile 

 terminal cymes (66) karroensis. 



Ultimate flowering branches (dried) ^-^ (rarely 

 1 lin.) thick ; involucres in terminal pedun- 

 culate cymes (1^) Burmanni. 



Glands at the base of the leaves or at the sides of the 

 leaf-scars none or very inconspicuous (in a few 

 species they are presout at the base of young 

 bracts and leaves, but are small and soon dis- 

 appear) : 



Branches terete, puberulous ; involucres sub- 

 sessile or \QYy shortly pedunculate, in 

 opposite pairs along or at the ends of the 



branches, 1-lJ lin. in diaru., with entire

(67) spicata. 



Branches more or less angular or terete, rough 

 (under a lens), especially along the angles, 

 with more or less evident asperities (not 

 hairs) upon the surface, apart from wrinkles 

 caused by shrinkage in drying : 

 Asperities formed of small laterally compressed 

 tubercleSj which sometimes seem to form 

 very narrow, wavy, crenulate wings ; 

 branches forking into terminal cymes : 

 Primary branches (dried) 1^-2 lin. thick, 

 often alternate, diatmctly angular and 

 the asperities very evident ; ultimate 

 divisions of the cymes 1^-3 liu. long ... (16) muricata. 



■ 



Primary branches (dried) |-1 liu. thick, 

 opposite, scarcely or obscurely angular 

 and the asperities often scanty ; ulti- 

 mate divisions of the cymes usually 3-9 

 liu. long, sometimes less (S2) arceuthobioides. 



Asperities formed of minute acute points or 

 blunt p;ipi!IsD : 

 Rudimentary leaves (not the bracts) with 

 a minute pj 'reading point or angle on 

 each side at the base ; cymes short, 

 racemosely arrangetl ; involucres dark 

 purple (60) caterviflora, 



Ixudiuientary leaves without points or angles 

 at their base ; involucres nut dark 

 purple : 

 Branches slender, terete, divided at their 



ends into lax cymes |-1J in. in diam. (57) tenax.
