iscutellariaafolia, Scheele^ L c. Gravelly liills of tlie 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, w^ h the leaves 



scarcely at all cordate. Var.? leptophylla : foliis linearibus integris vel remote denticulatis. 

 Near Howard's Springs; Bigeloio; No. 1796, Wright, Plant woody at the base, about a span 

 high, and branched from the base. Stem and branches sparingly hirsute. Leaves 1-1|- inch 

 long and 1-2 lines wide. Spikes few-flowered ; the lowest flowers fertile. Flowers as in T. 

 ramosa, etc. 



Tragia urenSj Linn, Sp, p. 1391 ; Ell. Sk, 2, p, 564. Hills on the lower Rio Grande ; Schott. 

 Tykia myriCxEFOLIA, Scheele in Linn<jeay 25, p. 581. Rocky hill sides near the Pecos and Live 



Oak creek, also on the Flounce mountains, etc.; western Texas and Chihuahua; Bigeloio^ Schott. 

 San Felipe, California ; Parry. No. 180G and 1807, Wright. An 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 acuminatisbasi attenuatis 

 prominenter trinervibus spinuloso-dentatis rigidulis eglandulosis. Stillingia spinulosa, Torr. 



Emory's Rep. p. 151. In the sandy desert west of the 



Major Ei 



Near Fort Yuma; Schott. Var. dentatum: foliis oblongis vel obovato-oblono^is obtusis vel acu- 



tiusculis membranaceis acute dentatis, dentibus inermibus, venis inconspicuis. Wet ravines, Ea^J-le 

 Pass, Lower Rio Grrande; Bigelow^ Schott. Valley of the Almo ; Parry, Near Monterey, 

 Neuvo Leon; Dr. Edioards & Major Eaton. These two forms differ considerably, but they 

 ; probably belong to one species. They are both undoubte Uy annual. 



; Sapium sylvaticum. Stillingia sylvatica, Linn. Mant. p. 126; EIL Sk, 2, p. 560. Var. linea- 



I 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 

 2^-3 inches long, 2-3-lines wide, somewhat coriaceous. Spikes androgynous, 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. K. Nov. Gen. & Sp. 2,^. 65. Between Rayon and Ures, Sonora; 

 Ihurher, ^* A shrub 10-12 feet high with somewhat erect and slender branches, and deep green 

 foliage." Leaves 1^-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 • -ti 2 minute 

 glands at the base. The specimens are in fruit. The capsule is solitary and apparently r.xillarj, on 

 a short peduncle, smaller than in S. sylvatica, but in other respects similar, and without any 

 remains of the staminate spike. On the Sierra de la Nayoz, in Sonora, Mr. Schott gathered 

 specimens of what seem to be the same plant. The leaves are similar in form, but a little wider, 

 more membranaceous and rather obtuse, or sometimes even emarginate. The staminate spikes 

 are without any fertile flowers at the base. There are 10-20 sessile flowers under each scale or 

 involucre. The calyx is manifestly 2-lipped, and the stamens seem to be constantly two, the
