192 Planted L>indheimerian<z. 



crosperma bartonioides, Walp. Repert. 5. p. 776, ty- 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, April, Dr. Gregg.) " Plant 

 succulent, full of aqueous juice." — Hooker's prior name of 

 Micro sperma 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 t. 234, 

 probably also M. rudis, Schauer in Linnaa, 20. 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.

 to me. Herbaceous, sub-erect, slander. Petioles 2, the 

 peduncles 3-3|, 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.
