H lines long, but h line broad: petals white, not equalling the alcB : 

 capsule orbicular, retuse, slightly margined. — Amongst 2oines, hills of 

 Patzcuaro, Michoacan, August, 1892 (n. 4151). A species much 

 resembling P. scoparia, HBK., but differing in its narrower and more 

 pointed sepals, and in its orbicular not at all oblong fruit. 



Abutilon attenuatum. Branches slender, terete, woody, stel- 

 late-pubescent : leaves lanceolate, attenuate, serrate, shallowly cor- 

 date, 2-2^ inches long, 10-12 lines broad, 3-nerved from the base, 

 green and finely pubescent with simple hairs above, somewhat paler 

 and soft pubescent with stellate hairs beneath : petioles 2-4 lines long : 

 flowers in open terminal subsimple racemes : pedicels spreading, 7-9 

 lines in length : calyx lobes pubescent, ovate, acuminate, 3 lines long : 

 corolla orange-yellow, once and a half as long as the calyx : capsule 

 hirsute with spreading setaceous tips. — Slopes of mountains near Lake 

 Chapala, Jalisco, November, 1892 (n. 4354). 



Pavonia melanommata. Two feet or more in height, finely 

 glandular-pubescent : leaves ovate, acuminate, attenuate, crenate, soft 

 pubescent above, velvety and cinereous beneath, 3-4 inches long, half 

 as broad, the radical considerably smaller ; petioles an inch long : pedi- 

 cels |-1J inches long: involucre of 5 linear bracts distinctly exceeding 

 the calyx ; the latter stellate-pubescent throughout : corolla externally 

 pubescent, 1^ inches in diameter, 3-4 times as long as the calyx, pur- 

 plish white with an almost black glabrous centre ; staminal column 

 bearing near the base a number of short dark spatulate appendages 

 (rudimentary stamens ?) : carpels glabrous, at maturity with sharp 

 lateral angles, slightly keeled dorsally. — Volcanic hills, Monte Leon, 

 Michoacan, November, 1892 (n. 4343). Possessing much the habit 

 of P. hirtijlora, Benth., but having ovate crenate leaves, corolla smooth 

 at the base within, and staminal appendages. 



Astragalus Tolucands. Root stout : stems several, slender, 

 ascending, knotted below, minutely appressed-pubescent : stipules lan- 

 ceolate, ciliate, acute, 2J-4 lines long: leaves H-2 inches long; leaf- 

 lets 9-1 2 pairs, petiolulate, oblong, truncate or retuse, 2^-3^ lines long, 

 glabrous above, appressed-pubescent below especially upon the midrib 

 and near the margin : peduncles not exceeding the leaves : racemes 

 dense, 1-2 or more inches in length : bracts oblanceolate to obovate, 

 acute, pubescent, 2-3 lines long, persistent : pedicels a line in length : 

 calyx light colored but covered with short black hairs ; the teeth nar- 

 rowly lanceolate, attenuate, 1| lines long, equalling the tube, densely 

 black hairy : standard obovate, retuse, 5-6 lines long, it and alte blue
