PIPER—CANAVALIA AND WENDEROTHIA 579 
upper lip truncate and apiculate, the small lower lip with 3 triangular acute 
lobes, the middle one longest; corolla 3 cm. long, apparently purple, streaked ; 
standard 3 em. long, oblong-ovate, obtuse or slightly retuse, clawed at base and 
with two shallow depressed glands near base, each thickened a little at the 
upper margin; wings linear, obtuse, twisted, 2 cm. long, much shorter than 
the keel; keel strongly falcate, long-rostrate, twisted in a single spiral near 
the bilobed apex; style glabrous; stigma terminal, capitate; pods linear, com- 
pressed, densely strigillose, 10 to 14 cm. long, 15 to 15 mm. wide, each valve 
with 4 longitudinal ridges, one close to each suture, one 4 to 6 mm. from the 
ventral rib and the fourth 4 mm. from the dorsal rib; seeds (scarsely mature) 
oval, compressed, constricted at the micropylar end, very dark brown, dull, 
7 to 8 mm. long, 5 to 6 mm. wide, 2 mm. thick; hilum linear, more than half 
as long as the seed, about one-fourth its circumference.

8. Wenderothia obidensis (Ducke) Piper. 
Canavalia obidensis Ducke, Arch. Jard. Bot. Rio de Janeiro 3: 173. 1922. 
The original description by Ducke is as follows: 
“erba volubilis minime tomentella, foliis ut in C. gladiat&é at minoribus 
et angustioribus (usque ad 7 cm. longis ad 2% c, latis). Flores quam in 
specie citat&éi minores, dilute roseo-violacei, calice angustiore, labii superioris 
lobis minoribus. Vexillum lamini circa 13 mm. longi 10 mm. lata basi bical- 
losA at non appendiculati unguiculo circa 6 mm.. longo; alae angustissimae ; 
carina in rostrum breve incurvum terminata. Ovarium pilosum, basi at- 
tenuatum. Legumen junius parce pilosulum, maturum glabrum, 11 ad 12 cm. 
longum 2 ad 2% em. latum, alis in utroque latere suturarum circa 3 cm. a 
sutura distantibus alAque longitudinali (in valvis medianfil) munitum. Semina 
1 em. vix longiora valde compressa % vel 84 cm. lata, nigra, nitidula, dura. 
“Species calicis formf ad sect. II accedit ubi C. gladiatae characteribus 
multis approximatur, at vexilli formf ad sect. I spectat ubi petalorum structura 
C. pictae Benth. affinis videtur. 
“Obidos, in terris argillosis ab Amazonum fluvio periodice inundatis inter 
vegetationem secundariam, A Ducke 12-8-1916 n. 16336. 
“Cette espéce a le calice du bien connu C. gladiata, mais le labre supérieur 
moins profondement bilobé; l’absence des appendicules de l’étendard, et l’aile 
médiane des valves de la gousse ne permettent pas de la confondre avec ce 
dernier.” 
The specimen in the National Herbarium has no flowers but does have 
nearly ripe pods. From this the following data are added: 
Apparently a woody climber; stems slender, terete, pale, glabrous; petioles 
slender, glabrous, shorter than the leaflets; petiolules sparsely puberulent ; 
leaflets rather thin, somewhat coriaceous, elliptic to lanceolate, truncate at 
base, obtuse and notched at apex, paler beneath, glabrous except.a sparse 
puberulence on the principal veins above, 4 to 8 cm, long, 2 to 3 cm. broad; 
glands at the base of the pedicels not prominent; pods woody, linear, sharp- 
pointed at tip, 10 cm. long, 2 cm. broad, dark-colored, sparsely strigillose, 
each valve with 3 winglike longitudinal ridges, one 4 mm. high close to the 
ventral suture, one 3 mm. high near the dorsal suture, and the third 2 mm. 
high about one-third the width of the pod from the ventral suture; seeds 
(immature) dark, shiny, much compressed, 12 mm. long, the dark linear hilum 
10 mm. long, more than one-third the circumference of the seed.
