leaflets rhombic-ovate or obovate, lucid and finely pubescent above, to 
mentulose beneath, destitute of setae and ciliation, pinnately veined; the 
lateral 1.5 to 2.5 cm. long, subsymmetrical, the terminal twice as large, 
oblique and with excentric midnerve: globular heads (7 mm. in diameter) 
white, racemosely disposed on the long spreading unarmed grayish to- 
mentose branches of a loose panicle; pedicels slender, 1 em. long: corolla 
4-parted to the middle, its lobes short-oblong, rounded at the apex: 
stamens 8: pods 5 cm. long, 7 to 10 mm. broad, glabrous and lucid 
upon the disarticulating valves but finely papillose under a strong 
lens, dark brown, unarmed except for a few scattered minute recurved 
spines upon the tomentulose replum; rectangular segments thin, broader 
than long. — Collected by the late Dr. Sereno Watson in the eastern 
portions of Vera Paz and Chiquimula, Guatemala, in 1885, nos. 323 in 
fruit and 185 in flower. Types in herb. Gray. This species of the sub- 
genus Habbasia is closely related to the South American MM. Spruceant, 
Benth. From this it differs, however, in the much less dense and less 
rufescent pubescence of the stem, more strongly armed petioles, less nume™ 
ous leaflets of different venation and finally in its much smaller fruit, 
which is at full maturity less than half as broad as in the Brazilian plant. 
Russelia Deamii. Stems becoming 1.6 m. long, 4-angled below, 
6-angled toward the ends, copiously branched, glabrous except 0D the 
- smaller branchlets, with slender ribs at the angles: leaves 1.5 to 2 cm. 
long, two thirds as wide, ovate, acute, incisely serrate except near the 
cuneate base, green, loosely pubescent and sparingly punctate aboves 
slightly paler and strongly white-villous beneath especially about the 
larger nerves and near the base: cymes numerous, 3-flowered ; peduncles 
slender, 4 mm. long, pubescent as are also the filiform slightly longer 
pedicels; bractlets linear: lobes of the villous calyx lance-acuminate 
rom an ovate base: corolla scarlet, 1.6 to 2 cm. long, the nearly equal 
lobes suborbicular: fruit not seen. — Collected at Cuernavaca, Mexico 
7 July, 1900, by Charles C. Deam, no. 30. This species differs from 
R. sarmentosa, Jacq., in its villous more incisely toothed leaves and 
6-angled branches, from R. jaliscensis, Rob., in the form of its calyx" 
lobes, from JR. polyedra, Zuce., in its larger flowers and glabrous less 
strongly ribbed stems as well as in the form and sharp dentation of the 
eaves.
