* ^-esembryanthemum mr- cellum, N, S. Brovm. -riootstock, a fleshy 

 cylindric tuber about l|--2 in. long and 4-5 lines thick, v/ith e 

 brOT.m skin, '^roducinp a cluster of stems at its apex. Stems £t-5 

 in. lonc', f-3/4 line thick, slender, vjeak and often bending down 

 with the weight of th*^ capsule, terete, glabrous but minutely pat)- 

 ill^te, with the papillae arranged in.crov.'ded irregular transverse 

 bands or lines. Leaves h-1 in lonp', li-li lines broad, and about 1 

 line thick, more or less spreading and scarcely connate at the 

 base, semiterete, tapering to an acute apex and channelled dovm the 

 urrer surface, glabrous, densely and minutely papillate in crov-.ded 

 longitudinal rows, dull grejash-green. ^lov/ers about 1-3 to a stem, 

 distant, develorinp" singly, v/ithout other flower-buds apparent on 

 the same stem. Pedicels 7-SO lines lonf?;, erect, ^^arillate like the 

 stem, brpctless. ^el'!n: 5-lobed; tube (ovary) sub-hemispherical; 

 lobes unerual, two of them 2|— 4 lines lonp-, leaf-like, v-ithout mem- 

 branous m^rp-ins, the others lf-2 lines lonp-, ant^ broader than the 

 other two, ^''^ith membr^-'nous margins and a short dorsal acute point, 

 all dull ereen and rarillate like the leaves. Corolla 7-|-10 lines 

 in diameter, rather fl^^^t expanding in sunshine, not scented; reta.ls 

 about 28-36, in 1-2 series, most of them, rather crowded and more' 

 or less overla^^ning, ^-idely spreadinp- from the base, 3-4| lines long,

 none; stie-mas 5, arising from the flat top of the ovary, 3/4-line long 

 striut, tarering to a fine point, all erect and connivent into a 

 cone, never spreading, pale greenish -yellow. Capsule about 3 lines
