-K. hi^achiatay E. Mever, or any other Soutli African pj^ecies living or dried that T 

 have seen. Besides the natiire of its scabrous stems, this species is readily dis- 

 tinguished from the true E, hraddata^ E. Clever, by the often alternate and very 

 niuch less divergent branches and diiierent inflorescence, proliably the involucres 

 will al:>o be found to diti'er. Thunberg's type consists of two small branches and 

 Pearson^s specimen of one branch only ; the latter is identical with the type 

 except that the stem shows only a slight trace of the six angles which are 

 conspicuous on that of Thunberg. ^ 



47, E. perpera (X, E. Br.); a much-branched succulent shniTi or 

 shrublet, leafless and spineless ; branches and branchlets all opposite 

 or forking, more or less constricted or jointed at their origin^ 

 diverging from each other at an angle of not more than 60''-75'^, 

 fleshy when young, glabrous ; leaves rudimentary, deciduous, scale- 

 like, opposite, sessile, spreading or %vith abruptly recurved tips, 

 i lin. long and more in breadtli, very broadly deltoid, acute, 

 scarcely channelled, glabrous; eymes terminal, ^-1 in. in diam., 

 formed of 2 diverging branchlets |-i in. long, each once or twice 

 forking into shorter branchlets, the ultimate bearing 3 involucres; 

 bracts shorter than the involucres, scale-like, ^ lin. long, deltoid- 

 ovate, acute or subobtuse, glabrous ; involucres sessile, f lin. in 

 diam., cup-shaped, glabrous, with 5 glands and 5 minute oblong 

 or spathulate-oblong slightly ciliate lobes; glands \ lin. in their 

 greater diam., transversely oblong or elliptic-oblong ; ovary ellipsoid, 

 trigonous, narrowing at the apex, glabrous ; styles ^-f lin. long. 

 United at the basal half, ascending-spreading above, with bifid tips ; 

 capsule about 1^ lin. long and 1] lin. in diam., trigonous, exserted 

 just beyond the involucre ; seed about 1 lin. long, pyramidal, sub- 

 truncate at the base, obscurely 4-angled, densely covered with very 

 minute whitish tubercles on a dark brown ground. E. hrarhirrfa,

This plant bears a superficial resemblance to E, murlcaia, Thunberg, but the 

 peculiar tubercles, gi'ooves and angles on the stems of that species are quite absent 

 from this and it grows in a different region, about 200 miles farther south. 

 Eoissier has associated this and 3 other perfectly distinct species under the name 

 of K brachtata^ E. Meyer, and I believe his description of the flowers and fruit 

 under that name are taken from this species. No specimen of /:. perpera exists in 

 E. 3reyer*3 Herbarium, his type of E, brachiata being quite di.<tinet from !t. 



48. E. Burmanni (E. Meyer in Drege, Zwei Pil. Documente, 184, 

 fx Boiss. in DC. Prodr. xv. ii. 75) ; a bushy plant, 1-2 ft. high 



(BhiUijjs)^ with the younger parts succulent, spineless and almost 

 leafless, dioecious ; main stems or branches about 2 lin. and the 

 flowering branches about ^-1 lin. thick when dried, glabrous, 

 green, not glaucous, drying greyish-green; branches opposite, 

 diverging at an ande of 5'f-7o'', ascending and forming at the
