Talinaria T. S. Brandegee, l. c., p. 231. 
Nov. Gen. Portulacacearum. Calyx ebracteatus, diphyllus; sepalis 
aequalibus, carnosis, reticulato-venosis, demum deciduis. Petala 5, hypo- 
gyna, libera, oblongo-ovata, exunguiculata, aestivatione imbricata, cito 
marcescentia. Stamina circa 25, in phalanges 5 petalis oppositas iisque 
adhaerentes disposita; filamenta filiformia; antherae biloculares. Ovarium 
uniloculare; stylus columnaris, apice trifidus, lobis oblongis intus stigma- 
tosis. Ovula numerosa, columellae centrali funiculis gracillimis inserta. 
Capsula oblongo-ovata, 3-valvis, epicarpio coriaceo, valvarum ab endo- 
carpio chartaceo dissiliente. ^ Semina numerosa, hamoso-reniformia, a 
latere valde compressa, ala membranacea cincta; embryo curvatus, albumen 
includens. 
Herba carnosa. Flores in pedunculis solitarii. Folia subradicalia. 
1. Talinaria Palmen T. S. Brandegee, l. c., p. 231. 
Herbaceous from roots bearing long tubers: leaves spatulate, pointed, 
8—9 mm long, 5—6 mm wide, crowded upon a short stem so as to 
appear rosulate, becoming rose-colored, the axils and lower parts bearing 
numerous white hairs: peduncle usually single, 15—20 mm high, with 
1—2 hyaline, quadrate bracts near the base that are pilose within and 
from which rarely a second peduncle grows: sepals rose-colored, broadly 
ovate, 6 mm long, deciduous at maturity: petals 8 mm long, 5 mm wide, 
rose-colored: stamens and style shorter than the petals: anthers yellow’ 
capsule oblong or ovate at maturity, 7--9 mm long; epicarp leathery, 
3-valved, deciduous from the base; endocarp persistent, reticulate mem- 
branaceous, 3-valved, the valves sometimes divided nearly to the base, 
the sutural nerves separating and resembling slender spines, the strong 
reticulated nerves also tending to separate: seeds enclosed in a white 
papyraceous aril that by pressure becomes flattened, and except at the 
hilum causes them to appear broadly wing-margined; cotyledons in- 
cumbent; embryo linear, curved into a half-circle about the albumen, 
testa smooth. 
This plant is related to Grahamia of Chile, from which it is disting- 
uished mainly by its bractless flowers, dissilient epicarp and incumbent 
cotyledons. The winged seeds and other characters are very different 
from those of Talinopsis, which it resembles in the structure of its capsule. 
Mexico: Collected at Saltillo by Dr. Edward Palmer in 1904, and 
by Dr. C. A. Purpus at Saltillo, and on rocks near Jxmiquilpan in 1905. 
2. Drymaria multiflora T. S. Brandegee, |. c., p. 232. P 
Perennial, growing in clumps from stems rooting at the joints: stems 
erect, branching, 4 dm high, striate, glabrous below, and above a portion 
of each joint glandular- pubescent: leaves broadly ovate to orbicular,
