COMPOSITAE NEW AND TRANSFERRED. 525 
The four species of Chrysactinia now known may be conveniently 
divided into two sections, habitally well marked but without differ- 
ential characters of technical importance. 
Curysactinia Gray (PI. Fendl. 93 (1849)) sect. Euchrysactinia 
Blake, n. sect. Folia subulata integerrima. Corollae radii discique 
aureae.— Type C. mexicana Gray. 
1. C. mexicana Gray, |. ec. (1849).— Leaves subulate, flattened 
above, hirtellous on the margin, mostly alternate, 4.5-12 mm. long, 
0.7-1.2 mm. wide, with rather numerous glands. Phyllaries appar- 
ently uniformly 12 in number, 4-5 mm. long.— Pectis taxifolia Greene!

3. C. prnnata Wats. ! Proc. Am. Acad. xxv. 154 (1890).— Leaves 
opposite, oblong, pinnatilobed almost to the midrib with 9-17 oppo- 
site oblique oblong to (uppermost) deltoid mucronate acute lobes, 
sparsely gland-dotted, 2.5-4.9 em. long, 1.2-1.9 em. wide, the lowest 
pair of lobes reduced and stipule-like. Rays 8, whitish, orange-tinged 
outside; disk orange.— Nuevo Leon: Pringle 2524 (rypE).— Described 
by Watson as herbaceous, but apparently frutescent like the other 
species of the genus. 
. C.TRUNCATA Wats. ! 1. c. (1890).— Leaves opposite or the upper 
alternate, ovate to ovate-oblong in outline, pinnatilobed nearly to the 
midrib with 3-7 mostly alternate lobes, the lobes entire or with 1-few 
spinulose teeth, truncate and glandular-mucronate at apex (or the 
terminal sometimes acute), 1.5-2.4 em. long, 8-12 mm. wide.— Nuevo 
Leon: Pringle 2601 (typr).— The rays are described by Watson as
