been referred to A. Texense (as ia Lemmon's and Pringle's Arizona 

 collections), ought to be distinguished, not only by the spreading or 

 trailing growth and the pubescence, but also by the color of the corolla. 

 In the original description this is said to be yellow : but I find no 

 authority for it in the collector's memoranda. It is noted as " brick- 

 red " on the ticket of specimens collected by Sir Joseph Hooker and 

 myself at Caiion City, Colorado, in 1877, and as " j^ink " by Dr. Ha- 

 vard in specimens from AV^. Texas. 



A. Thurberi, Gray. A pentacarpellary species, of Grisebach's 

 section Anasida, but wholly with one-flowered peduncles. Dr. Masters, 

 in Fl. Trop. Africa, i. 186, takes it to be very near A. ramosum {Sida 

 ramosa, Cav.) ; but that seems to be more like A. umhellatum. The 

 latter was collected by Berlandier in Mexico, not far from the Texan 

 boundary (no. 1549, 3049), is cinereous or somewhat canescent, usually 

 more than pentacarpellary, and the peduncles 3-5-flowered, the seeds 

 muriculate. 



A. HOLOSERiCEUM, Schccle, which is figured in Gen. 111. ii. t, 125, 

 as A. velutinum, is interesting as the only one of oi;r species which 

 bears a pair of collateral ovules and seeds in the upper part of each of 

 the five carpels, while the lower and narrower basal portion bears a 

 single seed. 



A. (Gayoides) crispum, Don. Common along the southern fron- 

 tier, usually with villous branches, while in Florida the var. imberbe, 

 Griseb. (^A. trichodum, A. Rich., and Sida imherhis, DC.) j^revails. 

 To this species belongs no. 92 of Parry & Palmer's Mexican collec- 

 tion, which has been inadvertently referred to Gaya suhtriloba. 



HIBISCUS, L. Accepting this genus with the limits assigned by 

 Bentham and Hooker, the subgenera, so far as North America is con- 

 cerned, would seem to be Euhibiscus, Abelmoschiis, and Paritium ; the 

 first, comprising the bulk of the genus, dividing into more or less 

 well limited sections. 



H. (Malvaviscoides) tubiflorus, DC. From the character and 

 the original figure, the outlines of which have been reproduced by 

 Alph. de Candolle, it seems safe to refer to this the H. Bancroftianus 

 of Macfadyen, the synonymy of which (excluding Malvaviscus penduli- 

 florus) is correctly detailed in Watson's Bihl. Index. To it I refer, 

 as a large-leaved form, no. 643 of Ghiesbreght, the leaves of which 

 are sometimes 3-cleft. 



H. LASiocARPUS, Cav. Diss. iii. 159, t. 70, f. 1. This is the oldest 

 and an appropriate name for the H. incanus of Schrader and Wend-
