on the face, the appendage coarsely lacerate in the middle, 

 parted into several club-shaped divisions at each side. Sta- 

 men-tube about 12 mm. long, saccate and short-spurred near 

 the base, the free portion of the unequal filaments 2-3 mm. 

 long, the anthers small. Stout style recurved above, exceeding 

 the anthers by 3 or 4 mm., the stigma incurved. Fruit, in- 

 cluding the wing, 2.5 cm. or more long, the narrow base 3 mm. 

 long, the strongly wrinkled body 12 mm. long by 6 mm. broad, 

 the lower wing 20 mm. long on the more or less dentate lower 

 edge, 16 mm. on the upper, its greatest breadth 6 mm. ob- 

 liquely oblong, blunt, slightly falcately recurved, finely niany- 

 nerved. Crest wing-formed, straight, nearly as long and 

 about as wide as the wing, slightly wider near the summit, 

 where it is 2 or 3 dentate. 



Sacupana, near the mouth of the Orinoco, April, 1896. 

 (Rusby and Squires No. 21.) 



Securidaca venosa. 



Specimen in fruit. Rachis, petioles, veins, fruit, etc., softly, 

 finely and rather sparsely puberulent. Branchlets very slen- 

 der, flexuous, terete. Petioles very short, biglandular at the 

 point of insertion, the blades 3 or 4 cm. long, 2, to 2.5 cm. broad, 

 oval and nearly elliptical, entire, revolute, thick, glabrous above, 

 with the midrib lightly impressed, the midrib and finely reticu- 

 late venation very prominent beneath, with the principal veins 

 puberulent, the principal secondaries 5 or 6 on each side. In- 

 florescence widely and loosely paniculate. Pedicels of the 

 fruit 5 to 7 mm. long, very slender, dilated and annulate at the 

 summit, the annulus thick. Fruits 4 cm. long, the body 8 mm. 

 long, obovoid, pubescent, very strongly reticulate, the marginal 

 ribs continued into the wing and crest, the lower one forming 

 the lower edge of the wide, 4-costate upper margin of the wing. 

 Greatest breadth of wing about 10 or 12 mm. its nerves strongly 

 falcate, their terminal portions nearly at right angles to the 

 margin. Crest nearly twice the length of the body, about 5 

 mm. broad, its upper margin thick, obtuse, its lower margin 

 continued into a short stout point. 



Near Ciudad Bolivar, Venezuela, Rusby and Squires, April 

 1896, without number. Very near Fendler's No. 2306 and ap- 

 parently the same as Jenman's No. 5005. Fendler's has a 

 broader wing and the crest acuminate and falcately incurved. 



Monnina Buchtienii. 



Short-tomentose throughout. Branchlets stout, densely leafy. 

 Petioles 6 mm. long, stout, broadly and shallowly grooved 

 above, the blades 4 to 8 cm. long, 2 to 4 cm. broad, ovate with
