5*. A. hastata, Cav. Annual, pilose or glabresoent; leaves hastate or lobed at the 

 base ; pedicels axillary, solitary, exceeding the leaves ; calyx profoundly 5-fid : lobes ovate,

 Diss. t. 11./. 'i,;As. Or. Gen.Dor.Jmer.t.lZi. — Hab. Naturalized in Jamaica!, ^ancr.; 

 [indigenous on the continent : New Mexico, Mexico ! to Peru !]. 



5. SIDA, L. 



Carpids 5-15, uniovulate, dehiscent towards the apex or indehiscent, tardily separating 

 from the central torus. Radicle superior. — Involucel (or obsolete). Suffrutescent herbs 

 (■usually flowering from the first gear, and consequently in that state appearing annual), 

 or shrubs. 



Sect. 1. Malvinda. — Calgx f>-fid or i-toothed : tube usually angular. Carpids birostrate 

 or bimucronate at the dehiscent apex (rarely uniaristate or awnless). 



t Leaves tapering or rounded at the base. 



* Flowe^s^^hortlg stalked o,r suhsessile: pedicel not jointed above the middle. 



)^ 6. S. carpinifolia, L. Sufiinitescent ; leaves eUiptical-lanceolate, serrate above the 

 base ; stipules linear, equalling the petioles and the pedicds ; flowers axillary, shortly stalked; 

 calyx 5-fid, exceeded by the yeaow petals ; carpids 8-10, reticulated, birostrate or bimucro- 

 nate, glabrous, hairy towards and upon the beaks. — Cav. Diss. t. 3./. 3, t. Z.f. 10, 11, t.

 S. Balbisiama, DC. S. brachypetala, DC. S. trivialis, Macf.l S. lanceolata, Bich. Cub. , 

 S. obtusa, Mch. — Habit of Malvastrum tricuspidatum. The great variability of this species, 

 by which we are justified in uniting these and other synonyms, affects chiefly the following 

 particulars : down appressed, stellate, or wanting ; leaves varying from rhomboid-lanceolate 

 to elliptic, acuminate or bluntish, quite glabrous or stellate-pubescent beneath, or strigose 

 'upon the ribs ; stipules lanceolate or setaceous, variable in length ; flowers usually fascicled, 

 or solitary ; the pedicels shorter than the petiole, or twice its length ; carpids glabrous, or 

 with a short down (chiefly above), their awns 3'"- J'" long, erect, or at length incurved. 



o. Carpids birostrate : beaks erect (of various length, hut usually exceeding the diameter 

 of the carpid). 



- /3. brevicuspidata. Carpids bimucronate : beaks very short. — To this form S. stipulata, 

 Cav., 8. acuta, Burm., and the greater part of the above synonyms belong; it was well 

 described by Macfadyen (5. trivialis, ej.l).

7. S. i^lomerata, Cav. Sufirutescent, downy chiefly by simple hairs; leaves lanceo- 

 late, serrate above the base ; stipules large, obliquely -lanceolate, acuminate, nervose, twice 

 the length of the petiole ; flowers axillary, suhsessile, glomerate or solitary ; calyx 5-fid, 

 equalling the yellow petals ; carpids 5, reticulated, glabrous, shortly biouspidate : valves at , 

 length subulate, divergent. — Cav. Diss. t. 3. /. 6. — In habit approaching the preceding. 

 Stem usually with a few or no branches, l'-3' high, either villous with simple hairs exceeding 

 the stellate down, or glabrescent ; leaves with a soft down, or scattered, simple, spreading 

 hairs on both sides ; carpids smaller, petioles shorter, and leaves narrower than in S. carpi-
