 it 8-9. 



Westkrx Regiox : Little Xamaqualand ; near the Orange River, without 

 precise locality, Paterson, and at Violrf Drift, liofjerif, 33S3 ! 



E. virosn is^ at present most imperfectly known, as the only speciuieu I have 

 seen that I think must certainly belong to it, is a fragment about 2 in. long from 

 the top of a stem, without flowers, collected at Viols Drift, which lies to the west 

 of the locality where Patersou found it. 



The only other specimens seen, which may or may not belong to E, virosa, 

 are :— (1) One collected by Dr. Marloth (4687)^^ Tsarras, in Great Namaqualand. 

 This consists only of the marginal 2>ortion of one of the flowering scol]oj>s of an 

 angle, accompanied hj a photograph of the plant, which seems to quite agree with 

 Paterson's figure in appearance. In this specimen 2-3 cymes are produced at each 

 flowering-eye, on stout peduncles J-1 lin. long ; involucre sessile, about 3 lin. in 

 diam., oboonic-cup-shaped, glabrous outside, with 5 glands and 5 broadly rounded 

 or ti'ansversely oblong minutely toothed lobes ; glands contiguous, 1 J-IJ lin. in 

 their greater diam., transversely oblong, entire ; ovarj' and capsule not seen, onl}* 

 the central male involucre being developed. This is the plant mentioned and 

 figured as E. Dinteri^ Marloth in Wissensch. Evgehn, Deutsch. Tiefsee-Exped, ii, iii. 

 52, 291, 313, Karte 8, not of Berger, (2) Tw^o other specimens, collected by 

 Prof. H. II. W. Pearson (8022, 80S5) on the Great Karasberg Range, in Little 

 Naniaqualand, and figured hy him in Annah of the Bolus Herharium, i. 42, as 

 E. rirosa, ditler from the Orange River plant in the following particulars. The 

 stems are much more slender, being only I J in. in diam. at the thickest part and 

 less than 1 in. at the apex, corresponding to the apex of the Orange River plant, 

 ^'hioh measures 2 in. in diam. at the same point. The leaves are stated by Prof. 

 Pearson in a letter to be *' about J-J in. long, oblong or slightly elliptic with a 

 broad base and almost acute apes " ; there are no leaves on the specimens, but 

 this descri2:»tion does not agiee with those on the Orange River specimen. Each 

 flowering-eye produces only one 3-flow^ered cyme on a peduncle ^-1 lin. long ; 

 involucre sessile, about If lin. in diam., campanulate, glabrous outside, apparently 

 yellow, with 5 glands and 5 broadly rounded or transversely oblong minutely 

 toothed lobes ; glands erect in the dried specimen, f-1 lin. in their greater diam., 

 transversely oblong, entire; capsule about 2 lin. long and 3J lin. in diam., 

 subacutely triangular, glabrous, erect, exserted g-1 lin. beyond the in>olucre ; 

 styles about J lin. long, united into a column almost to the apex, ^vith minute 

 spreading emarginate stigmas J-J lin. long ; seeds about 1 lin. long, oblong, 

 apparently 4-angled, but immature, smooth, areolate-reticulate. 



From the above it will be noted that both Marloth's and Pearson's plants difler 

 in certain particulars from E, virom, and I think it proKable that they belong to 

 tw^o other distinct, but closely allied species. This, however, can only be decided 

 ty a careful comparison of ample material of good flowering and fruiting specimens 

 of all three plants. 



173. E. grandicornis (Goebel, Pflanzenbiol. Schilclerung. i. 42, 59 

 and 63, figs. 15 (as E, grandklens), and 26, 29 and 30); a stout 

 succulent leafless bush, 2-6 ft. high, much branched from the base, 

 armed with very long spines; branches erect or ascending, very 

 deeply constricted into subsagittate-ovate or sagittate-reniform 

 segments 2-5 in. lon^ and 2-6 in. in diam,, 3-angled, with the solid 



<ientral part |-1 lin. thick, glabrous, green, not glaucous ; angles 



wing-like, l-24r in. broad and ^-} in. thick, wavy, with continuous 

 horny greyish-white margins ; leaves rudimentary, minute, scale- 

 Hke ; spines very stout, ^-2i in. long and 1-2 lin. thick at the base, 

 in pairs ^-11 in. apart/widely diverging, greyish or pale brown;
