BOTANY. 



twist of the cotton fibre, though, of course, too scant and short to be utilized. 

 I am indebted to Mr. Watson for the following statement : 



"It is the same as 1751 Wright, 946 and 1013 Thurber, 191 Wislize- 

 nus ; also collected by Coulter and Berlandier. It is G. globosa, var. 

 albiflora, Moq. in Bot. Mex.. Bound. It is (without critical comparison), 

 however, very much nearer G. decumbens, but has acuter bracts." 



I am led to regard it as distinct from globosa, var. albiflora (which is 

 " G. eriopoda, Gillies in Herb. Hook "), and certainly it is not G. decumbens, as 

 in the latter only the interior sepals are silky, and the outer ones are 

 obtuse, whereas in my specimens all are silky and acute. 



Froelichia* Floridana, Moq. — Cinereous-tomentose or woolly, erect, 

 1-3° high. Stem leafy below, nearly naked above ; radical leaves lanceo- 

 late, obtuse, on rather long petioles ; inflorescence in racemose spikes 6-12" 

 long, and covered with a fulvous wool ; bracts dark, shorter than the calyx, 

 which is woolly when young and hardens with age, becoming flattened, 

 cristate and tuber culate at the base. — Camp Bowie, Arizona (488). 



Amarantus fimbriata, Benth. (Sarratia Berlandieri, var. fimbriata, 

 Torr. in Bot Mex. Bound, p 179. Amblogyne fimbriata, Gray, Proc. Amer. 

 Acad, v, p. 168). — " Stem and branches virgate ; leaves linear-lanceolate, 

 the globose glomerules sessile in the axils of the leaves, and in nearly leaf- 

 less spikes above, approximate or crowded, the pointless bracts shorter than 

 the calyx ; sepals of the male flowers obtuse, of the female connate, sub • 

 equal, narrowed at the base, flabelliform-cuneate, at the apex dentate- 

 fimbriate, widely spreading in fruit. Utricle circumcissile." — Nevada and 

 Arizona. 



Amakantus Torreyi, Benth. (/Sarratia Berlandieri, cum var. emarginata, 

 Torr. I. c Amblogyne Torreyi, Gray, Proc. Amer. Acad, v, p 169). — " Dioe- 

 cious, leaves ovate-oblong or oblong-lanceolate; glomerules paniculate- 

 spiked and axillary ; bracts and sepals of the male flowers cuspidate- 

 acuminate. Sepals of the female flowers united below, equal, obovate- 



* Frcelichia, Mcench. — " Flowers perfect, 3-bracted. Calyx tubular, 5-cleft, indurated and spiny- 

 crested in fruit. Stamens 5, united into a long tube. Sterile filaments entire, anthers sessile. Stigma 

 capitate or many-cleft. Utricle indebiscent, 1-seeded, included in the calyx. Seed vertical. Radicle 

 ascending. Woolly or hairy annuals. [My specimens appear to have u, biennial or perennial root.] 

 Leaves opposite. Spikes opposite, and terminating the naked peduncle-like summit of the stem." — 

 Chapman's Flora of the Southern United States, p. 383.
