4. Wenderothia palmeri Piper, sp. nov. 
Stems slender, terete, densely soft-canescent or near the tips fulvous-pubes- 
cent; petioles densely pubescent, about as long as the leaflets; stipules and 
stipels not seen ; leaflets membranaceous, oval to ovate, obtuse to acute, weakly 
apiculate, green and strigillose above, densely soft-canescent beneath, 3 to 6 
cm. long; peduncles stout; thyrses about 6-flowered; pedicels 2 to 4 mm. long, 
the gland at base of each prominent, semiglobose; calyx bracts suborbicular, 
canescent; calyx 1.5 to 2 cm. long, densely canescent or slightly rusty-pubescent, 
the orbicular emarginate upper lip equaling or exceeding the tube, the small 
lower lip with three broadly ovate, acutish, subequal teeth 5 mm. long; corolla 
purple, 3 cm. long; standard 3 cm. long, elliptic, slightly emarginate, reflexed, 
attenuate at base into a short broad claw, bearing at the base of the blade a 
linear callosity on each side of the median groove; wings shorter than the 
keel, linear, twisted, the basal auricles rounded, the slender claw 6 mm. long; 
keel 3 cm. long, falcate, petals united above the middle to the tip into a narrow 
twisted beak, each auricled at base and with a slender claw 6 mm. long; style 
glabrous; stigma capitate; pod (immature) linear, 10 em. long 2 cm. broad, 
densely soft-canescent, one rather prominent longitudinal ridge close to the 
ventral suture, a less prominent one very close to the dorsal suture, and a 
median one nearer to the ventral than to the dorsal suture; immature seeds 
with the hilum nearly as long as the seed. 
Type in the U. S. National Herbarium, no. 266512, collected at Acapulco, 
Mexico, 1894-95, by Edward Palmer (no. 575). This same collection in the 
Kew, Gray, and New York herbaria bears the number 375, 
Mexico: Sierra Madre, Michoacin or Guerrero, Langlassé, February, 1899 
(U. S., Kew, N. Y., Gray). Tonali, Chiapas, Nelson 2881 (U. 8.). 
Closely allied to W. villosa and W. hirsuta, but differing from both in the fact 
that the leaflets are not acuminate, and by the intermediate characters of the 
lower calyx lip. 
5. Wenderothia mattogrossensis (Rodr.) Piper. 
Mucuna mattogrossensis Rodr. Pl, Mattogr. 15. 1898. 
Canavalia mattogrossensis Malme, Ark. fér Bot. 4': 9. 1905. 
Stems herbaceous, slender, terete, white-puberulent; petioles densely pubes- 
cent, shorter than the leaflets; stipules “minute, setaceous” (Rodrigues) ;: 
stipels minute; leaflets membranaceous, oval or slightly ovate, rounded or 
slightly subcordate at base, obtuse, rarely acutish, never acuminate at apex, 
apiculate, sparsely white-puberulent above, more densely so beneath, 4 em. 
long; peduncles puberulent, 2 to 3 em. long, shorter than the 10 to 12-flowered 
thyrses; bracteoles ovate, acutish, 2 mm. long; calyx 18 mm. long, densely 
canescent, the truncate apiculate upper lip shorter than the tube, the lower 
lip 3 mm. long, the lateral teeth ovate, acute, the median ovate, triangular,, 
acuminate, longer and narrower; corolla “lilac’’ (Malme,) or “blue violet” 
(Lindman) ; standard 3 em. long, oblong, emarginate, the sides reflexed, at- 
tenuate at base to a broad claw 7 mm. long, bearing toward the: base two 
prominent conic callosities; wings as long as the keel, linear-spatulate, loosely 
coiled, short-unguiculate and bearing at base of blade a small obtuse inflexed 
auricle ; keel 3 cm. long, narrow, falcate, rostrate, inflexed at tip, unguiculate at 
base, each petal with a small oblong auricle at base, the two petals united 
toward their tips; stamens monadelphous; anthers oblong-linear ; ovary linear, 
pubescent; style glabrous; stigma capitate; pods not seen but according to 
Rodrigues’s description and figure nearly straight, beaked at tip, stipitate, 
11 to 12 em. long, densely hirsute-villous with chestnut-colored hairs, the 
valves 3-ribbed, one rib near each suture, the third near the middle.
