Disci glandulae florum c^ carnosae rotundatae; florum 9 glandulis co- 
haerentibus annulo irregulari formantes. Capsulis glabris laevibus. Se- 
mina fusca leviter sulcata (sulcis dorso parallelis, faciebus arcuatis et 
concentricis). 
La structure du testa des graines, celle des jeunes rameaux à angles 
spinuleux, la forme des glandes des fleurs c^ aussi bien que celle des 
fleurs 9, les sépales à large marge hyaline, séparent très nettement 
cette espèce de l’Andrachne telephioides dont elle a le port.

X., pt. 3 (1906), p. 93. 
Caulescent, about 70 em long, leafy below, glabrous, glaucous, the 
basal leaves several; lower stem leaves weak, 40 to 60 cm long, 3 to 
4 em broad, thin, a little glaucous, with a véry narrow scarious margin 
only slightly serrulate; inflorescence 6-branched, the branches 20 to 
30 em long, the bracts scarious, each subtending 3 (rarely 2) flowers; 
perianth 6-parted, yellow, the three outer lobes linear-oblong, the others 
oblong, 14 mm long, 6 to 7 mm broad, all reflexed in full flower but

Mexico: Collected by J. N. Rose and Jos. H. Painter on bluff at 
Tepoxtlan, Morelos, September 2, 1903 (no. 844), and flowered in 
Washington, November, 1904. : ; 
This species is nearest E. reflexa, but is more leafy and has a more 
branched inflorescence.

191. Castalia gracilis (Zuce.) Rose, I. c., p. 94. 
Syn.: Nymphaea gracilis Zucc. Abh. Akad. Muench., I, 362, 1832. 
Mr. Conard's reference of N. gracilis to N. ampla does not seem 
borne out by a careful study of the original deseription of N. gracilis or 
by an examination of material which seems to belong to that species. 
Mexico: This species is common in the Valley of Mexico and 
throughout the Valley of Lema. 
192. Castalia pringlei Rose, |. c., p. 94. 
Rhizomes apparently horizontal, large, 30 to 60 cm long; leaves 
orbicular, 25 to 30 em in diameter, entire, retuse at apex, not at all 
peltate, the sinus generally closed or the lobes overlapping except the 
short acute tips, glabrous throughout, somewhat purplish beneath, the 
veins not prominent; flowers very large, 12 to 15 cm in diameter, white; 
sepals 5, thin, oblong, obtuse, green except the more or less whitish 
margins; petals pure white, oblong, obtuse; stamens yellow, the outer 
ones with broad petaloid filaments, the inner with shorter and narrower 
filaments; connective scarcely longer than the anther. 
This species is perhaps near C. odorata, but differs in having the
