Echinocactus—continued. 
E. viridescens (greenish). . yellowish-green, rather large, 
produced from the upper clusters of spines. Stems ovate or 
globose, sometimes lft. high and Yin. to 12in. in diameter ; »ines 
radiating, unequal, three of them usually larger, broad, acumi- 
nate, transversely striated. California, 1877. A plant at Kew, 
about fifteen years old, is only 6in. high. 
E. Visnaga. The correct name is £. ingens.

E. Wislizeni (Wislizen’s). 1. greenish-yellow, about 2in. long 
and broad, developed only on large plants. Summer and autumn. 
Stem depressed when young, large and cylindrical when old; 
ridges about a score, r Jar and sharp-edged, bearing bundles 
of spines at regular intervals, the outer and shorter ones being 
white and spreading, while from the middle of each tuft arise 
three 2in. long and one 3in. long, with the point hooked, and as 
strong as steel. See Fig. 362. 
E. napinus and E, Odieri are very rare in cultivation. 
ECHINOCYSTIS (from echinos, a hedgehog, and 
kystis, a bladder; in allusion to the prickly fruit). Orp. 
Cucurbitacer. A genus embracing about fifteen species of 
stove, greenhouse, or hardy, prostrate or climbing, annual 
or perennial herbs, all American. Flowers white, small or 
mediocre, moncecious; males racemose or paniculate ; 
females solitary or borne with the males in the same axil. 
Fruit dry or berry-like, armed with long spines, one- to 
three-celled. Leaves palmately five- to seyen-angled. 
E. lobata, the only species calling for mention here, is a 
hardy, nearly glabrous climber, thriving in a moist, rich 
soil. Propagated by seeds. 
FE. lobata (lobed). /l. greenish-white, small; sterile racemes often 
lft. long. July to September. jr. nearly 2in. long, armed with 
weak prickles; seeds jin. long. /. membranous, mucronately 
aety lobes triangular. North America. (R. H. 1895, 
p)9, 4. 1. 
ECHINOPS. The species number about seventy, and 
are distributed over South Europe, tropical and North 
Africa, and Asia, as far as Japan. 
ECHINOPSIS. The growing and resting seasons for 
Echinopsis are the same as for Echinocactus, and we may 
therefore refer to what is said under that genus for general 
hints with regard to the cultivation of Echinopsis in this 
country. None of the species require to be grafted to grow 
freely and remain healthy, as the stems are all robust

The only danger is in keeping the plants too moist in 
winter, for although a little water now and again keeps 
the stems fresh and green, it deprives them of that rest
