Hibiscus. MALVACEiE. 235 



base about J of an inch in Icnijtli. Segments of the calyx lanceolate, atten- 

 uated, with an oblong colored spot on the inside of each, near the base. 

 Petals broadly cuneiform, slightly emarginate, cream-color tinged with 

 purple. Stamineal column less than half the length of the petals : outer one 

 hispid externally, lobed below the middle; the anthers in a single row, about 

 5 at the summit of each of the lubes: inner one irregularly lobed, rather 

 shorter than the outer, and connate with it a little above the base. Styles 

 plumose, included : stigmas simple. Fruit not seen. — A remarkable species 

 resembling some Bombaceai in its stamineal column.

 7-parted ; segments divided into linear rather obtuse lobes ; flowers in a 

 long leafy raceme ; lobes of the calvx lanceolate ; styles 7. 



St. Barbara, Upper California, Nullall !— 11 Stem 8-12 inches high. 

 Leaves about H inch in diameter, divided nearly to the base into narrow 

 segments. Flowers about an inch in diameter. Petals obovate-cuneiform, 

 purple, slightly emarginate. Styles hairy on the inside: stigmas simple. 

 Fruit not seen. 



18. .S. coccinea (DC.) : stellately pubescent and hoary ; leaves on long

Plains of the Upper Missouri, above the confluence of the Platte, Nuttall, 

 James! Plains of the Saskatchawan, Drummond! — 1i About a span 

 high, branching. Leaves 1-li inch in diameter; the lobes often obtuse, 

 broadly linear. Raceme many-flowered : pedicels about 2 lines long. Flow- 

 ers an inch in diameter, scarlet. Petals truncate and emarginate. Stamineal 

 column half the length of the corolla. Stigmas capitellate. " Carpels about 

 6, compactly and circularly arranged." Hook. — The calyx is certainly not 

 involucellate in this species ; but we have not had an opportunity of ascer- 

 taining whether the seeds are like those of Sida. 



19. (S. dissecta (Nutt.! mss.): stellately pubescent and hoary; leaves 

 5-parted to the base; lateral segments 3-cleu, the middle one multifid; ulti-

S. crispa (Linn.) is recorded by some writers as a native of Carolina; but we 

 strongly doubt whether it has been found native within the limits of our Flora.
