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. 



I. Chrysactinia Gray (PI. Fendl. 93 (1849)) sect. Euchrysactinia 

 Blake, n. sect. Folia subulata integerrima. Corollae radii discique 

 aureae. — Type C. mezicana Gray. 



1. C. MExiCANA Gray, 1. c. (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. — • Pedis taxifolia Greene! 

 Leafl. i. 148 (1905): see Greenm. Field Columb. Mus. Bot. ii. 274 

 (1907). — Western Texas and New Mexico to Puebla. 



2. C. ACEROSA Blake. — Leaves filiform-subulate, glabrous, mostly 

 opposite, bearing 2-4 glands, 6-8 mm. long, 0.25 mm. wide. Phyl- 

 laries 8 in number, 3.5 mm. long. — San Luis Potosi. 



IL Chrysactinia sect. Phylloloba Blake, n. sect. Folia 3-17- 

 pinnatilobata. Corollae radii albidae et aurantiaco-suffultae vel au- 

 reae; corollae disci aurantiacae vel aureae. — Type C. pinnata 

 Wats. 



3. C. PINNATA 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^.9 cm. long, 1.2-1.9 cm. wide, the lowest 

 pair of lobes reduced and stipule-like. Rays 8, whitish, orange-tinged 

 outside; disk orange. — Nuevo Leon: Pringle 2524 (type). — Described 

 by Watson as herbaceous, but apparently frutescent like the other 

 species of the genus. 



4. C. truncata Wats. ! I. 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 cm. long, 8-12 mm. wide. — Nuevo 

 Leon: Pringle 2601 (type). — The rays are described by Watson as 

 bright yellow. 



Coreopsis basalis (Dietr.) Blake, n. comb. — Calliopsis hasalis 

 Dietr. in Otto & Dietr. Allgem. Gartenzeit. iii. 329 (17 Oct. 1835). 

 Calliopsis Drummondii D. Don ! in Sweet, Brit. Fl. Gard. ser. 2. iv. t. 

 315 (1838). Coreopsis Drummondii (D. Don) Torr. & Gray, Fl. N. 

 Am. ii. 345 (1842). — The long and detailed description by Otto & 

 Dietrich of their Calliopsis basalis shows it to be identical with the
