ALVARADOA AMORPHOIDES Liebm. 
This tropical American plant was found in Caldwell’s Hammock, 
Dade Co., by Dr. Britton and Prof. Rolfs, March 26, 1904 (no. 
260). During May of the same year Mr. Wilson and the writer 
found it in neighboring hammocks (no. 1708) and on Long Key 
(mainland) (no. 1872). 
Linum Carteri sp. nov. 
Annual, bright green: stem erect, 1-3 dm. tall, simple or some- 
late, entire, minutely spine-tipped, sessile: bracts glandular-serru- 
late: flowers short-pedicelled: sepals lanceolate or ovate-lanceolate, 
acuminate, 4.5-5 mm. long, rather evenly glandular-serrulate, but 
the inner rather more finely and regularly so than the outer: corolla 
yellow; petals broadly cuneate, 10-12 mm. long, mostly emar- 
ginate: filaments glabrous: styles united to near the tips, glabrous: 
capsule ovoid, 4 mm. long, blunt, surpassed by the sepals. 
A very showy species related to Linum rigidum Pursh, peculiar 
in being the only representative of the group to which that species 
belongs, known east of the Mississippi River. It may be separated 
from Linum rigidum by the smaller sepals with finer and less 
prominently glandular teeth and the relatively broader and shorter 
capsule. The type-specimens were collected in the pinelands 
between Cocoanut Grove and Cutler in November, 1903 (Small & 
Carter, no. 758). In March, 1904, Dr. Britton found specimens 
in the homestead country beyond Cutler (no. 170), while in May, 
1904, Mr. Wilson and the writer discovered it in great abundance 
between the last named locality and Camp Longview (no. 1721). 
Linum Curtissii sp. nov. 
ual, glabrous: stems erect, 2-6.5 dm. tall, corymbosely 
hace above, or sometimes simple, ee striate in age: leaves 
mainly alternate, ascending or erect: oblong-spatulate or 
oblanceolate on the lower part of the oe . linear or nearly so 
above, 0.5-1.5 mm. long, acute or acutish or somewhat acuminate, 
entire: flowers short-pedicelled: sepals 2-2.8 mm. long, ovate, 
mes narrowly so, somewhat acuminate, the outer with few 
mm. broad: capsules spheroidal, about 2.5 mm. high, surpassed by 
the sepals.
