CROTONS OF THE UNITED STATES. At 
em. long, 3- to 6-flowered, the pedicels about 2 mm. long or 
by exception longer; sepals oblong-spatulate, about 4 mm. 
long, apex acute, marginal glands sessile or short stipitate, 
rarely absent; petals represented by subulate processes 
1 mm. or so long; styles 3, palmately 4-parted or abruptly 
twice biparted, 3 to 5 mm. long, stellate; capsule globose, 
4to5 mm. tall, trigastric; seeds oval, depressed at the 
oblong caruncle. 
These forms have been alternately referred to C. bal- 
samiferus and C’. humilis. C. balsamiferus, according to 
Muell. Arg., who makes it a variety of C. flavens, has 15 
to 20 stamens and a biparted style. C. humilis has twice 
biparted styles and 30 to 35 stamens. The Florida forms 
of C. Berlandieri Torrey have 15 to 20 stamens and twice 
biparted styles, while the Texas forms have 30 to 35 
stamens, and similarly divided styles. All our forms are 
less glandular and more pubescent and have shorter pedi. 
celled flowers than the Jamaica forms of C. humilis. 
Mueller vy. Arg. in DC. Prodromus leaves us in doubt as to 
just how he interpreted their affinities. Under Hucroton 
we have ‘*C. Berlandieri (Torr. Mex. Bound. Surv. 
p. 193) * * * In Novo Mexico ad Nuevo Leon 
(Thurber n. 708, Berlandier no. 2125 ex. Torr.).’’ Under 
Astraea he has C’. humilis and the following citations: 
«© * * * * in Mexico orientali prope Matamoros (Ber- 
landier n. 2125!), nec non in Florida (Cabanis! in bh. 
berol.),’’? and as a synonym ‘‘ (. Berlandiert Torr. Mex. 
Bound. Surv. p. 193(ex hb. Kew).’’— Plate 6.
