PIPER—CANAVALIA AND WENDEROTHIA 585 
Wenderothia glabra Mart. & Gal. Bull, Acad, Sci. Brux. 107: 191. 1843, The 
original specimens, not seen, are from Hacienda de Mirador, Veracruz. The 
only points in the description that seem diagnostic are the white flowers and 
the minutely fulvous-pilose stems. Specimens from the type locality, Nelson 
90, Linden 723, and Sartorius 2800, have the fulvous-pilose stems, but the 
corollas in the Sartorius and Linden specimens are certainly purple. 
Wenderothia pilosa Mart. & Gal. Bull. Acad. Sci, Brux. 107: 191. 1841. The 
type collection is Galeotti’s 3273 from Zacuapan, Veracruz, and duplicates 
are in the herbarium at Kew. The only unusual feature of the specimens is 
the spreading fulvous pubescence of the stems, perhaps best described as 
thinly short-pilose. ‘The pubescence of the under leaf surface and of the 
calyx is similar but less erect. 
Stems perennial, woody, terete, climbing, more or less densely pubescent, 
hirsutulous to strigillose, rarely quite glabrous; petioles about as long as the 
leaflets, varying in pubescence like the stem; petiolules 4 to 6 mm. long, 
usually densely puberulent; stipules lanceolate, attenuate, 3 mm. long; leaflets 
4 to 10 cm. long, thin to rather thickish, membranaceous, oval to ovate or 
somewhat obovate, sometimes merely acute, usually with a more or less elon- 
gate acuminate apex, the tip blunt and apiculate, rounded to subcordate at 
base, sometimes glabrous or nearly so on both sides, usually sparsely strigil- 
lose above, strigillose to densely tomentulose beneath, the pubescence usually 
whitish but varying to ferruginous; peduncle stout, usually longer than the 
young inflorescence, this 10 to 25-flowered; pedicellar glands very prominent ; 
thyrses 10 to 30-flowered; bracteoles ovate-orbicular, 2 to 3 mm. long; calyx 
campanulate, 12 to 15 mm. long, glabrous to strigillose or tomentulose, canes- 
cent to ferruginous, the truncate apiculate upper lip nearly as long as the 
tube, the lower lip 3-lobed, 2 to 3 mm. long, the lateral lobes ovate-triangular, 
thinner and shorter than the median lobe; corolla reddish purple (white in 
W. glabra, according to Galeotti) ; standard 3 to 3.5 cm. long, elliptic to ob- 
long-ovate, emarginate, reflexed below the middle in anthesis, not auricled at 
base, bearing two elongate callosities below the middle, the claw 1 cm. long; 
wings linear-oblong, obtuse, at length twisted, shorter than the keel, a rounded 
inflexed auricle at base of blade of each; keel 3 cm. long, long-rostrate, falcate, 
the two petals united from above the middle to the tip, each with a small 
basal auricle, the tip often coiled into a single spiral; style glabrous; stamens 
monadelphous; pods nearly straight, beaked, compressed, 10 to 20 cm. long, 
1 to 1.5 cm. wide, densely tomentulose with white to ferruginous hairs, the 
valves 3-ribbed, one rib near each suture, the median one about twice as far 
from the dorsal suture as from the ventral; inner layer of pod closely ad- 
herent; seeds oval in outline, compressed, chestnut-colored, sprinkled with 
unequal brown dots, 10X7X4 mm., the dark hilum surrounded by a nearly 
black border, and extending one-eighth to one-fourth the circumference of the 
seed. 
Study of the extensive series of specimens listed seems to indicate that 
all the names cited pertain to but a single species ranging throughout Mexico 
and south into Panama. The forms vary mainly in the amount of pubescence 
on the calyx and leaves. ‘This pubescence is usually short-appressed on 
the calyx and leaves and commonly white, but not rarely tomentulose or short- 
pilose and frequently ferruginous. In all the specimens cited the leaflets are 
similar in form and alike in being acuminate, the tip blunt and apiculate. 
They vary however in texture as well as amount of pubescence, these doubt- 
less being fluctuating variations due to environmental influences. Bentham 
in publishing C. villosa described the lower lip as entire, but a reexamination 
of the type shows it to be 3-lobed. The lateral teeth are often small or obscure,
