retuse, abruptly narrowed below into a rather long claw: legume linear, 
about 3 cm. long, compressed, glabrous. In general appearance JZ. 
repens, Don, resembles H. Zorreyi, Gray, but in the repent habit, the 
very long peduncles, and in the longer claw of the standard, as well as in 
the conspicuously blackened petiolules, it is quite different. 
Hosackia oaxacana. An herbaceous perennial: stems erect or 
ascending, 1 to 2.5 dm. high, usually branched, glabrous: leaves includ- 
ing the short petioles 1.5 to 3 cm. long, 5-9-foliolate ; stipules narrowly 
ovate, 3 to 5 mm. long, acute; leaflets somewhat rhombic-obovate or 
oblong-obovate, 0.5 to 1 cm. long, 3 to 6 mm. broad, obtuse or sub- 
mucronate, green above, pale and somewhat glaucous beneath, having a 
few scattered hairs on the midrib beneath and on the margins, otherwise 
glabrous: peduncles usually exceeding the leaves, 2.5 to 5 cm. in length, 
glabrous ; umbels 3—6-flowered, subtended by a nearly sessile 1-3-foliolate 
leaf-like bract: flowers purplish, 1.2 to 1.4 em. long: calyx-teeth 
slightly unequal, triangular-ovate, 1.5 to 2 mm. long, acutish, sparingly 
pubescent, barely one half as long as the glabrous more or less purplish 
and somewhat glaucous tube ; standard obovate, slightly retuse, narrowed 
below into a claw, not auricled at the base or subcordate : mature fruit not 
seen. — Collected by the late Rev. Lucius C. Smith, Sierra de Clavellinas, 
Oaxaca, altitude 3,000 m., 26 June, 1894, no. 57. The affinity of this 
species is perhaps with the Californian H. gracilis, Benth., but it is readily 
distinguished from it by the shorter petiolate leaves, the much shorter- 
petioled and less conspicuous leaf-like bract subtending the umbellate 
floral cluster, by the shorter broader and more obtuse calyx-lobes, and 
finally by the subcuneate rather than distinctly auricled or subcordate 
standard.

(reprint p. 5). This species, although originally described as having 
“sharply spinulose-denticulate” leaves, seems to vary considerably in 
the character of the leaf margin. It not infrequently happens that even 
on the same individual specimen one finds leaves from perfectly entire 
to sharply spinulose-dentate. This variation is well shown by Pringle’s 
no. 8033, in herb. Gray. To this species may also be referred, as a 
form with entire or subentire leaves, Pringle’s no. 8002, collected on the 
Sierra de Pachuca, 21 February, 1899. ; 
Strrax Ramirezi, Greenm. Proc. Am. Acad. xxxiv. 568. This 
species, described from flowering specimens, has been collected in’ the 
fruiting stage by Mr. C. G. Pringle on the Sierra de Tepoxtlan, 
Morelos, altitude 2,300 m., 7 February, 1898, no. 8023. The fruit,
