150 PHANEROGAMIA. 



hirsute both sides. Peduncles umbellate-crowded, 3 or 4 lines long, 

 simple, one-floivered, naked, or with one or two bractlets, like those of 

 the involucel, which are 2 or 3 in number, linear-setaceous, gla- 

 brous or stellately ciliate, half the length of the calyx. Calyx hirsute 

 externally, nearly glabrous within, five-cleft nearly to the middle, 2 to 

 3 lines long. Corolla white or purplish, a little longer than the calyx, 

 hairy at the base externally. Fruit not seen. 



Allied to M. rhizanthum and M. acaidej but smaller in all its parts, 

 and hairy.* 



8. Malvastrum ulophyllum, Sp. Nov. 



M. nanum, e radice fusiformi rnulticeps, acaule; foliis confertis, petiolo 

 dilatato stipulisque adnatis ?iudis, lamina reniformi-rotundata flabel- 



* Malvastrum acaule {Malva acaulis, Cav. Diss. 2, t. 35), of which there are 

 specimens in the Hookerian herbarium, from Matthews (Huamantanga) and M'Lean, 

 has hairy petioles, &c, sharply toothed and incised leaves, longer and usually more than 

 one-flowered peduncles, and larger flowers than M. rhizanthum. I have not seen the 

 fruit, which, however, is said to be tomentose. 



Malvastrum parnassi^efoltum (Sida pamassicefolia, Hook Ic. PL t. 385), from 

 the Quitensian Andes, has larger flowers than M. rhizanthum, on peduncles as long as 

 the obsoletely toothed leaves; the calyx is hirsute, and the petioles are hispid-ciliate. 



Malvastrum Purdlei (Sp. Nov.): acaide, hirsutum ; radice fusiformi maxima; 

 foliis cordato-rotundis sublobatis crenato-dentatis glabratis ; pedunculis in collo umbellato- 

 confertis petiolis brevioribus apice capitato-trifloris ; bracteolis involucel! 'i 2-3 lanceolatis; 

 fructu tomentoso depresso, coccis omnino muticis. — Andes of New Granada, Mr. Purdie. 

 A species nearly allied to M. acaule, and with flowers about the same size : but the 

 peduncles (which are less than an inch long, even in fruit) are terminated by a capitate 

 cluster of about three flowers, which are not pedicellate. The bractlets of the involucel 

 are glabrous, or nearly so ; but the calyx is hirsute externally. Corolla purple. Carpels 

 about 15, almost orbicular, tomentose on the back, not muricate nor roughened. 



Malvastrum humile {Malva humilis, Gillies, in Hook. Bot. Misc. 3, p. 150), as 

 formerly mentioned in Plantae Fendlerianas, p. 21, belongs to the section of which the 

 North American 31. coccineum is the type. 



Malva Bettoa, Gay, Fl. Chil. 1, p. 304, t. 7, is a true Malvastrum; and so probably 

 are all the other really indigenous Chilian species referred to Malva in the same work, 

 except Malva sulphurea of Gillies, which is a Sida. 



Sida pygmoza, Remy, in Ann. Sci. Nat. ser. 3, 8, p. 238, from the Bolivian Andes, is 

 probably a Malvastrum.
