192 Piante Lindheimeriane. 
erosperma bartonioides, Walp. Repert. 9. p. 776, & Ann. 
Bot. Syst. 1. p. 794; Hook. Bot. Mag. t. 4491. On per- 
pendicular rocks, near New Braunfels. April, in flower. 
(Also on rocky cliffs near Ojito, Apih Dr: Gregg.) * Plant 
succulent, full of aqueous juice." — Hooker's prior name of 
Microsperma must give way to Eucnide, Zucc., as there is a 
much older genus Microspermum of Lagasca, also Mexican. 
Eucnide lobata (Microsperma lobata, Hook. Ic. Pl. 1. 234, 
probably also M. rudis, Schauer in Linnea, 90. p. 721, as 
the stamens are not always as short as in Hooker's figure), 
was likewise gathered near Monterey, Saltillo, &c. by Dr. 
Gregg, and at Zimapan, by Coulter. 
PASSIFLORACEJE. 
PASSIFLORA TENUILOBA (Engelm. Mss.): “petiolis brevi- 
bus eglandulosis; foliis supra pilis brevibus subscabris subtus 
glabriusculis trinerviis reticulatis basi biglandulosis subcordatis 
trilobis, lobis lateralibus lanceolato-linearibus elongatis cuspi- 
datis horizontaliter divergentibus vel recurvatis, medio brevis- 
simo in fol, inferioribus integro in superioribus breviter trilobo ; 
stipulis setaceis ; pedunculis binis petiolum bis superantibus ; 
cirrho elongato simplici ; floribus exinvolucratis apetalis ; calyce 
5-lobo virescente. — On the Liano; coll. in October. — Ap- 
parently near P. normalis, L., of Jamaica, which is unknown 
to me. Herbaceous, sub-erect, slender.  Petioles 2, the 
peduncles 3~33, lines long. Leaves rather rigid, with revo- 
lute margins, 5 or 6 lines long, but from 3 to 5 inches in trans- 
verse diameter; the lobes about 3 lines wide, the lateral ones 
sometimes bearing a posterior tooth or lobule. Flowers 8 or 
9 lines in diameter, Only a single specimen was gathered by 
Lindheimer.” - Engelm. in litt. — I have this plant from Mr. 
Wright, gathered two years since, between San Antonio and 
the Rio Grande. Fine fruiting specimens also have just 
reached me in the collection made by this enterprising botanist 
last summer between San Antonio and El Paso, New Mexico. 
The fruit is about the size of a musket ball. Seeds ovate, 
acute at both ends, tuberculate.
