 bus; racemis terminalibus axillaribusque dense floriferis 2-4 cm. longis, 

 rhachis albovillosis ; bracteis ovato-lanceolatis 6- 10 mm. longis acuminatis 

 subchartaceis brunneis sericeo-villosis ; floribus pedicellatis, pedicellis 3-5 

 mm. longis puberulis; calycibus sericeo-pilosis persistentibus, denti- 

 bus acutis ; petalis purpureis vel pallido-purpureis ; leguminibus stipitatis

 San Bernardino, District of Teotitlan, altitude 2000 m., 11 December, 

 1907, C. Conzatti, no. 2117 (hb. Field Museum, cat. no. 225895, type); 

 Sierra de San Felipe, altitude 2430 m., 13 October, 1894, C. G. Pringle, 

 no. 4983 (hb. Field Museum, hb. Gray, hb. U. S. Nat. Museum, and 

 hb. N. Y. Bot. Garden) distributed as ".Desmodium Jaliscanum Wat- 

 son." Valley of Oaxaca, altitude 2000-3000 m., 3 October, 1894, E. W. 

 Nelson, no. 1528 (hb. U. S. Nat. Museum); mountains of Telixtlahuaca, 

 altitude 2285 m., 18 October, 1895, Rev. Lucius C. Smith, no. 868 (hb 

 Gray); Cuicatlan, altitude 500 m., 2 December, 1897, C. Conzatti & V. 

 Gonzalez, no. 659 (hb. Gray); Oaxaca, 23 October, 1899, E. W. Nelson, 

 no. 3723 (hb. Gray). The species here described differs from D. 

 jaliscanum Watson in having uniformly shorter petioles, smaller leaflets 

 and puberulent pods. D. Conzattii suggests D. amplifolium Hemsl., 

 but that species again has longer petioles, larger leaflets, and stipules 

 of quite different outline.

In addition to the material cited under the orginal publication, the 

 following collections well represent this species: Real del Monte, State 

 of Vera Cruz (?), Mexico, Dr. Th. Coulter, without number (hb. Gray); 

 banks of the Avenida Hidalgo, Tezuitlan, State of Hidalgo, Mexico, 

 27 October, 1908, Barnes & Land, no. 549 (hb. Field Museum).

Fruiting specimens collected at Cerro San Antonio, Distrito del 

 Centro, State of Oaxaca, Mexico, altitude 1700 m., 6 September, 1908, 

 C. Conzatti, no. 2239 (hb. Field Museum), agree well with the type of 

 this species in the Gray Herbarium and with material secured at San 

 Jose del Cabo, Lower California, 9 September, 1890. The species has 

 not been recorded hitherto outside of Lower California. Notwith- 

 standing the considerable remoteness of Professor Conzatti 's station 

 from the peninsular localities for the species there can be no doubt of 

 the identity of the Oaxaca specimens with the above species.
