Wet Mountain Valley. EUPHORBIA STICTOSPORA, Engelin. in Bot. Mx. Bound., p. 187; Boiss. in DC. Prod., 15, 2, p. 41. Abundant on the saline fiats about Canon City ( Brandegee).- This common New Mexican species is thus shown to extend into Southern Colorado. It is a prostrate annual, readily known by its pubescence, which extends to the sharp angled capsule. It has rounded, subcoitiate, sharply serrate leaves; lateral, leafy, crowded racemes, with very small and slender long- peduncled involucres and slender sharply Wangled rugose-dotted seeds, which are about as long as the involucre itself ( about 0.6 lines long). The styles are short and undivided.- GEO. ENGELMANN. EUPHORBIA FLAGELLIFORMIS, new species. Annua, glaberrima; caulibus e basi pluribus ramosissimis declinatis sen decumbentibus; foliis breviter petiolatis e basi subins& quali lineari-bus subacutis mucronulatis integris; stipulis triangulari- lanceolatis in-ferioribns connatis superioribus distinctis; involucris solitariis pedicello rcquilongo fultis late campanulatis intus hirtulis polyandris, lobis tri-angularibus glandulas 2- 4 parvas concavas angustissime appendiculatas aequantibus; stylis brevibus erectis bifidis; capsula depressa trisulca; seminibus lsevibus cinereis trigonis acutis.

Originally sparingly collected without fruit on the Bio Grande, near El Paso, by Charles Wright. This species, as it now proves to be, was abundantly seen on the sandy flats of the San Juan River, in Southwestern Colorado, by Mr. Brandegee, where it occurs with the allied K petaloidea, but unfortunately it seemed to be too common to make specimens of I Stems 6- 12 inches long; leaves 6- 9 lines long, J to 1 line wide; involucres about | line wide; seeds of same length.- Readily distinguished from the allied JE. petaloidea by the smaller involucre bearing very small and almost naked glands, often less than four in number, the more numerous stamens ( often up to 25) with much smaller anthers, and by the smaller, more angular and more pointed, grayish seeds, while those of the allied species are larger, thicker, with rounded angles, and of a more reddish color.- GEO.
