BOTANY. 201 
scutellarisefolia, Scheele, l. с. Gravelly hills of the Limpio; Bigelow. Ravines of the Organ 
mountains, April; Parry. On the upper Rio Grande, New Mexico; Fendler, No. 776. Perhaps 
only a var. of the last. It differs chiefly in being much smaller and erect, with the leaves 
scarcely at all cordate. Var.? LEPTOPHYLLA: foliis linearibus integris vel remote denticulatis,— 
Near Howard’s Springs; Bigelow; No. 1796, Wright. Plant woody at the base, about a span 
high, and branched from the base. Stem and branches sparingly hirsute. Leaves 1-11 inch 
long and 1-2 lines wide. Spikes few-flowered ; the lowest flowers fertile. Flowers as in T. 
ramosa, etc. 
TRAGIA URENS, Linn. Sp. p. 1391; ЕП. Sk. 2, p. 564. Hillson the lower Rio Grande; Schott. 
TYRIA MYRICH/FOLIA, Scheele in Linnea, 25, p. 581. Rocky hill sides near the Pecos and Live | 
Oak creek, also on the Flounce mountains, etc.; western Texas and Chihuahua; Bigelow, Schott. 
San Felipe, California; Parry. Хо. 1806 and 1807, Wright. Ап irregularly branched 
homely shrub, 3-10 feet high, of a grayish green color, clothed with a minute stellate pubes- 
cence. Sterile flowers on short pedicels which are aggregated upon spurs or short branches and 
articulated at the base. Sepals mostly 3, sometimes 4. Stamens 3-20, the filaments distinct, 
with minute alternate capitate pedicellate glands at their base. No abortive ovary. Fertile 
flowers sessile. Fruit tricoccous or by abortion dicoccous. 
SAPIUM? ANNUUM (n. sp.) : annuum, humile ; foliis rhombeo-oblongis acuminatis basi attenuatis 
prominenter trinervibus spinuloso-dentatis rigidulis eglandulosis. Stillingia spinulosa, Torr. 
in Emory's Rep. p. 151. In the sandy desert west of the Colorado, California; Major Emory. 
Near Fort Yuma; Schott. Var. DENTATUM: foliis oblongis vel obovato-oblongis obtusis vel acu- 
tiusculis membranaceis acute dentatis, dentibus inermibus, venis inconspicuis. Wet ravines, Eagle 
Pass, Lower Rio Grande; Bigelow, Schott. Valley of the Almo; Parry. Near Monterey, 
Neuvo Leon; Dr. Edwards $ Major Eaton. These two forms differ considerably, but they 
probably belong to one species, They are both undoubte Пу annual. 
SAPIUM SYLVATICUM. Stillingia sylvatica, Linn. Mant. p. 126; Ell. Sk. 2, p. 560. Var. LINEA- 
RIFOLIA : foliis anguste-linearibus argute serrulatis, serraturis glandulosis. Ravines on the 
San Pedro river and on limestone rocks higher up on the Rio Grande; Schott, Bigelow. Leaves 
21-3 inches long, 2-3-lines wide, somewhat coriaceous. Spikes androg: nous, 1-2 inches long, 
2-4 of the lowest flowers fertile. Staminate flowers 5-10 on short pedicels under each scale or 
involucre. Calyx hemispherical, 2-lipped ; the border slightly crenulate. Stamens 2: filaments 
united at the very base. 
SAPIUM SALICIFOLIUM, H. B. К. Nov. Gen. ё Sp. 2, p. 65. Between Rayon and Ures, Sonora; 
Thurber. “А shrub 10-12 feet high with somewhat erect and slender branches, and deep green 
foliage." Leaves 14-2 inches long, and 3-4 lines wide, somewhat coriaceous, rather acute, 
remotely denticulate, the upper side (when dry) of a verdigris green color, often with 2 minute 
glands at the base. Тһе specimens are in fruit. The capsule is solitary and apparently axillary, on 
a short peduncle, smaller than in 8. sylvatica, but in other respects similar, and without any 
remains of the staminate spike. On the Sierra dela Nayoz, in Sonora, Mr. Schott gathered 
specimens of what seem to be the same plant. Тһе leaves are similar in form, but a little wider, 
more membranaceous and rather obtuse, or sometimes even emarginate. The staminate spikes, 
are "нове any fertile flowers at the base. There аге 10-20 sessile flowers under each scale or 
“Те calyx is manifestly — and the stamens seem to be constantly two, the 
ES is odi
