4. Meibomia painteri Rose & Standley, sp. nov. PLATE 51, a. 
Stems herbaceous, climbing, stout, angled, rather sparingly uncinate-hirsute; 
leaves large, trifoliolate; petioles 3 to 7 em. long, stout, uncinate-hirtellous; 
leatiets orbicular or broadly oblong, all of about the same size, 3 to S cm. long, 
sparingly strigillose above and more densely so beneath, slightly paler beneath, 
the veins large and conspicuous; petiolules stout, 5 to 7 mm. long, hirtellous; 
stipules persistent, ovate; inflorescence of simple, axillary racemes, or these 
sometimes sparingly branched, 2 or 3 from each axil, the branches uncinate- 
puberulent; flowers not seen; pedicels 6 mm. long; bracts deciduous: loment of 
1 or 2 joints, on a stipe 8 mm. long, the lower. joint often abortive, the terminal 
one sometimes smaller than the basal; constrictions very narrow; joints 
orbicular-reniform, 10 to 12 mm. long and almost as wide, with a shallow suture 
upon the upper edge, the center hard and turgid, surrounded by a rather thin 
wing, the whole strongly reticulate-veined, sparingly and very finely puberulent. 
Type in the U. S. National Herbarium, no, 690911, collected in Iguala Canyon, 
near Iguala, Guerrero, Mexico, September 21, 1905, by C. G. Pringle (no. 18688 ). 
From all other species of the group this may at once be distinguished by its 
orbicular leaflets and the peculiar inflorescence. The joints of the loment, too, 
are not like those of any other species. 
The species is named for Mr. J. H. Painter, formerly Assistant Curator in the 
Division of Plants of the U. S. National Museum, who, at the time of his death, 
was preparing to monograph the genus Meibomia. He had indicated this plant 
as a new species in the herbarium, but failed to give it a name.

hirtellous; leaves ample, numerous, trifoliolate; petioles 25 to 60 mm. long, 
vather slender, uncinate-hirtellous; stipules lanceolate, attenuate, deciduous; 
leaflets ovate to ovate-lanceolate, rounded at the base, acute, mucronate, 7 to 11 
cm. long, glabrous and shining above with an almost metallic sheen, thick and 
coriaceous, sometimes sparingly pubescent in the youngest leaves, densely soft- 
pubescent or sericeous beneath, most of the hairs whitish but those along the 
conspicuous veins bright yellow and longer; petiolules stout, 2 or 8 mm. long, 
densely pubescent with tawny hairs; inflorescence of terminal, sparingly 
branched panicles, or of simple, axillary racemes, the branches stout, densely 
uncinate-hirtellous; flowers on slender pedicels 6 mm. long; bracts soon de- 
ciduous, lanceolate, long-acuminate, 4 mm. long, hirsute; calyx finely puberulent,

short-acuminate; corolla purple; loment raised on a slender stipe 3 mm. long, 
of usually 2 joints, the lower one often abortive; joints quadrate-orbicula#,
