mentioned in several places in Mailotli, Kai)land, according to a pl.otograpli so 

 named, sent by Dr. Marlotli to Mr. Herger, is a totally different plant with nn- 

 branched stems and much smnller or no spines, and is apparently the same as that 

 above quoted in Engler's PHanzenreich. 



148. E. griseola. Pax in Engl. Jahrb. xxxiv. 375. A succulent 

 bush, spiny and leaHess. Branches less than h lin. in diam., elongated, 

 decumbent, 5-angled ; angles sinuate-toothed, with continuous grey 

 horny margins; teeth about 4-5 lin. apart. Spines 3-4 lin. long, in 

 pairs, grey, with black tips, with a pair of minute prickles at their base. 

 Involucre not described. Capsule small, about 1 lin. long and twice as 

 much in diam., deeply 3-lobed as seen from above, with keeled lobes. 



The above is the original dis rijition of this plant, which was collected in South 

 Africa at Lohatsi, in litchnanaland {Marloth, 3413), and wliich I have not seen. 

 liut a specimen collected in Rhodesia and named by Pax as being a variety of 

 E. griseola is as follows : 



Plant up to 3 ft. high. JJranchos (dried) i in. in diam., 5-angled; angles acute, 

 toothed, with continuous horny grey margins and concave faces between them; 

 teeth 2i-5 lin. 'apart. Leaves rudimentary,^-,] lin. long, ovate, acub', recurved, 

 soon deciduoas. Spines 3-4 lin. long, in pairs, widely diverging, grey, often blackish 

 at the tips, with or without a pair of very minute or rudimentary prickles at their 

 base. Cymes on peduncles ^,-|- lin. long and \ lin. thick, with 3 involucres. Bracts 

 scale-like, oblong, rounded, minutely tootiied. Involucre \h lin. in diam., some- 

 what funnel- sliaped, glabrous, with 5 L'lands and 5 erect subqnadrate fringed lobes 

 overtopping them ; glands contiguous, f-f lin. in their greater diam., transversely 

 oblong, entire. Ovary and capsule net .oceii.
