160. E. squarrosa (Haw. in Phil. Mag. 1827, 276) ; a very dwarf 

 succulent tuberous-rooted perennial, spiny, leafless ; tuber (or main 

 stem) ovoid or oblong, 1 \ in, or more thick, producing many 

 branches at its apex ; branches radiately procumbent l-J-3 in. long, 

 7-9 lin. in diam. including the teeth, 3-(4 ?)-angled, more or less 

 twisted, "convex on the under side" (Haivorth), glabrous, dark 

 green, without paler markings ; angles very deeply cut into rather 

 slender widely spreading cylindric-conical tubercles 2-3 lin. long 

 and I2-2 lin. thick at the base, each tipped with a pair of spines 

 |-1^ lin. long, not vei^y divergent, light brown ; leaves rudiuientary, 

 minute, scale-like, roundish-cordate, soon deciduous ; cymes solitary 

 in the axils of the tubercles, subsessile, 1-3-flowered ; bracts 

 minute, scale-like, shorter than the involucre, oblong, obtuse, dark 

 reddish; involucres about 2 lin. in diam., glabrous, green, suffused 

 with purple under the 5 glands and apparently w^ith purplish lobes; 

 glands contiguous, |-1 lin. in their greater diam., transversely 

 oblong, green. Boiss. in DC, Prodr. xv. ii. 81. 



South Africa : without locality, Bowie, cultivated specimen ! 



Described partly from a specimen from a plant cultivated at Kewin 1875, which 

 was believed to be one of the original plants introduced by Bowie, and partly from 

 two very fine coloured drawings preserved at Kew, made in 1824 and 1827 from 

 the plants from Avhich Haworth prepared his description and which were intro- 

 duced by Bowie in 1823, No other collector appears to have found it. In habit 

 it is very similar to L\ stellata, AVilld., and E. micracantha, Boiss.. but the long 

 tubercles on the angles of the branches readily distinguish it from both. 



161. E. mamillosa (Lem. Illustr. Hort. ii. Miscell. G9, in note) ; 



succulent, leafless, spiny, about 5-6 in. high, very much branched ; 

 branches tuberculate ; tubercles crowded, spirally arranged, elongated, 

 conical, dilated at the base, somewhat compressed laterally, cylindric 

 at the apex, bearing a very small roundish- deltoid scale-like leaf and 

 a pair of spines, which are subconnate at their base, then diverging ; 

 flowers axillary, only seen in bud, not described. Boiss. in DC. 

 Prodr. XV. ii. 80. Anthacanfha mamillosa, Lem. Lc, 69, 



Country unknown ; probably from South or Tropical Africa. 

 No specimen seen. Can it be E, squarrosaj Haw. ? 



162. E.stellata (Willd. Sp. PI. ii. 886); dwarf, succulent, spiny, 

 leafless, with a tuberous rootstock; tuber elongated-oblong, 3-6 in. 

 long, 1-2| in. thick, producing a tuft of radiating branches at its 

 apex ; branches procumbent, 2-6 in. long, 4-7 lin. broad, 2-angled, 

 slightly concave or flattish on the upper side, convex or very 

 obtusely keeled on the lower side, often tapering into a stalk at the 

 base, toothed at the angles, glabrous, green or purplish-brown, with 

 a feather-like whitish-green variegation along the upper side ; spines
