This ^vell marked species forms a connecting link between the tuberous-rooted 



group to which E. tuherosa and E. elliptica belong and the group with succulent 



tuberculate stems, through such species as E. clandestina and E. DaryL For it ia 



evident that the succulent stem of E. hupIeurifoUa is merely an above ground 



development of the subterranean tubers of the E. tuherosa group, its large 



•deciduous leaves and the character of the inflorescence being quite of the same 

 nature. 



85. E, clandestina (Jacq. Hort, Schoenbr. iv. 43, t. 484); stem 

 solitary, unbraiiclied (always?), i-1 ft. (or perhaps more) high, 

 1 -1 J in. thick, cylindric or cyliudric-clavate, fleshy, spineless, 

 covered with slightly recurved or ascending stout tubercles 2-4 lin. 

 prominent, in several spiral series, and bearing when in flower a 

 crown of leaves at the apical part with solitary sessile involucres 

 surz^ounded by and included in a cup formed of bracts in their axils, 

 minutely puberulous on the upper part, becoming glabrous below ; 

 leaves terminating the tubercles, |-1^ in. long, 1-2 lin. broad, 

 linear or linear-oblanceolate, acute and slightly recurved at the 

 apex, tapering to the base, more or less longitudinally folded, some- 

 what fleshy, minutely puberulous beneath, at least at the basal 

 part; bracts 7-9, imbricate; inner series 2 lin. long, 1-1| lin. 

 broad, ovate-oblong, obtuse, apiculate, glabrous, ciliate, green ; 

 ■outer series gradually smaller and more or less puberulous on the 

 back, purple ; involucre sessile, about half as loner as the inner 



^^i^acts, about 1^ lin. in diam., cup-shaped, minutely puberulous, 

 with 5-7 glands and 5 subquadrate minutely toothed lobes ; glands 

 ^"•|- lin. in their greater diam., transverse, narrowly oblong, entire, 

 puberulous on the under side, glabrous on the upper, yellow ; capsule 

 sessile, twice as long as the involucre, 2| lin. in diam., subglobose, 

 slightly narrowing at the top, with 3 slight furrows, minutely 

 puberulous ; styles free, ^- lin. long, spreading, shortly bifid at the 

 ^ex; seeds not seen. Poir, Enajd. Siqypl. ii. 610; Spreng. Si/st.

86. E. Davyi (N. E. Br.) ; very dwarf, succulent, spineless ; 

 body or main stem of the plant subglobose to elongated-obconic or 

 obovoid, with the greater part buried in the ground and only rising 

 1-1| in. above it, about 2 J in. in diam. in the only specimen seen, 

 subtruncate or broadly rounded at the top, covered Avith large
