ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 43 
Harpalyce arborescens (Gray, Proc. Am. Acad. 5: 178. 1861, 
The type was based on Ervenberg’s no. 18 from ‘*near Tantoyuca,”’ in northern 
Vera Cruz. Here, also, Dr. Gray referred T. Coulter's no, 556 from Zimapan, but it 
is doubtless to be placed elsewhere. 
Leaflets 3 or 4 pairs, oblong, 3 to 5 cm. long, obtuse or hardly retuse, in age nearly

glabrous above; calyx densely reddish-pubescent. Type in herb. Gray. 
Harpalyce formosa DC. Prod. 2: 523. 1825. 
The type of the genus. A Mexican species, only known from the tracings of 
Mocilio & Sessé. 
Harpalyce hidalgensis Taub. Bull. Herb. Bois. 3: 615. 1895. 
The type was collected by Seler (no, 658) in the State of ‘‘ Hidalgo, prope Huejutla.”’ 
The type locality of this species is very near that of JZ. arborescens Gray, with which 
it should be very carefully compared. 
The plant of Coulter’s referred to FH. arborescens may belong here. The leaflets 
are 6 pairs. 
Harpalyce loeseneriana Taub, Bull. Herb. Bois. 3: 612. 1895. 
The type of this species came from ‘‘prope Mitla,’’ State of Oaxaca, and was 
collected by Seler (no. 59). 
Perhaps here should be placed Lucius C. Smith’s no. 45. 
Harpalyce retusa ( Benth.) Rose. 
Brongniartia retusa Benth. in Hemsl. Diag. Pl. Noy. 1: 8. 1878, 
Fruit + cm, long, 18 mm. broad above the middle, cuneate at base; leaves thinner 
and pubescence of calyx whiter than in FH. arborescens. 
The type locality of this species was said to be ‘‘Tula,’’ but there are three places 
in Mexico of this name, one in the State of Oaxaca, another in Hidalgo, and a third 
in Tamaulipas. It undoubtedly came from the latter State. The two numbers (nos. 
759 and 2179) cited by Hemsley are in the Gray Herbarium, and the labels state 
that the plants were collected by Berlandier between Tula and Tampico, therefore in 
the State of Tamaulipas. Here Pringle collected his no. 7286 (1896), which agrees 
with these type sheets of B. retusa. 
CLIMACORACHIS, A NEW GENUS. 
Climacorachis Hemsl. & Rose, gen. nov. 
Calyx strongly 2-parted; banner orbicular; keel considerably shorter than the 
wings, obtuse; stamens in 2 clusters of 5 each; ovary stipitate; pod oblong, 
obtuse, 2 to 4 seeded, not at all jointed or constricted between the seeds, probably 
dehiscent. 
Low, wiry shrubs, with pinnate leaves, numerous small leaflets, peltate, striate 
stipules, and inflorescence consisting of a short zigzag, striate-bracted raceme. 
Flowers yellow, bibracteate at base. 
Inflorescence and foliage resembling Aeschynomene, but the pods very different. 
It should probably be placed between that genus and Herminiera. 
Native of the mountains of western Mexico. 
Type species, (. mevricana, 
Climacorachis mexicana, Hemisl. & Rose, sp. noy. 
Much branched, 2 to 4 dim. high, glabrous throughout except in the inflorescence; 
branches slender and wiry; leaflets 9 to 12 pairs, linear, 4 to 5 mm. long, strongly 3- 
nerved below, mucronately tipped; inflorescence 2 to + flowered; pubescence on rachis, 
bracts, bractlets, pedicel, and calyx more or less setose, consisting of long yellowish 
hairs, with shorter, perhaps viscid, hairs intermixed; bractlets ovate, acute, 2mm. long;
