GREENMAN. — MEXICAN PLANTS. 309 



retuse, abruptly narrowed below into a rather long claw : legume linear, 

 about 3 cm. long, compressed, glabrous. In general appearance H. 

 repens, Don, resembles H. Torreyi, 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 'l.o dm. high, usually branched, glabrous : leaves includ- 

 ing the short petioles l.o to 3 cm. long, 5-9-foliolale ; stipules narrowly 

 ovate, 3 to 5 mm. long, acute ; leaflets somewhat rhombic-obovate or 

 obloug-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 cm. long: calvx-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 Californiau H. gracilis, Benth., biit 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. 



Arbutus glandulosa, Mart. & Gal. Bull. Acad. Brux. ix. 533 

 (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. 



Styrax Ramirezii, 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,
