Blake — New Plants from South and Central America. 121 



persistent, 2 to 3 mm. long; pedicels stout, glabrous, articulate with calyx, 

 1.2 to 1.6 cm. long, bearing near or below middle a pair of oval or suborbicu- 

 lar bracts about 2 mm. long; calyx glabrous, the campanulate sub terete 

 tube 4 mm. long, the limb 3 to 4 mm. high, 9 mm. wide, the 5 teeth sub- 

 orbicular, apiculate, 2 mm. high; corolla ovoid-cylindric, ventricose below, 

 "rose-red," 17 to 19 mm. long, 5 to 6 mm. in diameter below, everywhere 

 glabrous, the 5 teeth somewhat spreading, triangular-ovate, acutish, 3.5 

 mm. long; stamens 10, equal, the linear-oblong glabrous filaments 3.8 mm. 

 long, the densely muriculate anther sacs 5 to 5.5 mm. long, the tubules 2, 

 connate, 4.8 to 5 mm. long, each opening by a longitudinal slit for more than 

 half its length; style exserted about 4 mm. 



Type in the U. S. National Herbarium, no. 1059981, collected in moist 

 region on slopes of Volc^n Irazu, Costa Rica, altitude 3050 meters, June 

 28, 1920, by Wilson Popenoe (no. 1017). 



According to Mr. Popenoe, this species grows sometimes as an epiphyte 

 and sometimes on the ground. Its nearest relative, Macleania turrialbana 

 Donn. Smith, also of Costa Rica, has oval or elliptic-oblong leaves, acutish 

 to broadly rounded at base, spreading or pendulous racemes, and tubules 

 (despite the original description) somewhat longer than the anther sacs. 

 In Horold's synopsis of the genus M. turrialbana is incorrectly placed in 

 the group with anthers produced into a single tubule. In the type ma- 

 terial they are produced into 2 connate tubules. Macleania costaricensis 

 (Klotzsch) Horold, of which I have seen no material, is apparently close 

 to M. irazuensis, to judge from the abbreviated original description, but 

 it is placed by Horold, who had presumably examined material, in the 1- 

 tubular group. 



Macleania laurina Blake, sp. no v. 



Scandent shrub; stem stout, obscurely puberulous, glabrate, very leafy; 

 leaves variable; petioles stout, obscurely puberulous or glabrous, 3 to 11 

 mm. long; leaf blades ovate to oblong-elliptic, 5 to 11 cm. long, 2.5 to 3.5 

 cm. wide, acute to obtusish, at base rounded to rounded-cuneate, entire, 

 not revolute, thick-coriaceous, sparsely short-hirsute with dark hairs which 

 often leave little pits on falling, penninerved, the chief lateral veins about 

 3 pairs, impressed above, prominulous beneath, the secondaries few and 

 obscure or obsolete; raceme axillary, subumbelliform, spreading-puberu- 

 lous, its axis 2 cm. long, about 20-flowered; pedicels clavate, 1.5 to 2 cm. 

 long, spreading-puberulous, articulate with calyx, bearing 2 or 3 deciduous 

 bractlets near the base; calyx densely puberulous, the tube campanulate, 

 subterete, 3 mm. high, the limb 5 mm. high, 8 mm. wide, the 5 lanceolate 

 to narrowly subulate teeth 1 to 2 mm. high; corolla ovoid-cylindric, ventri- 

 cose below, "rose-pink, waxy," 1.8 to 2.2 cm. long, 7 mm. in diameter 

 below, densely griseous-puberulous outside, glabrous within, the 5 triangu- 

 lar-ovate erect acutish teeth 2.5 mm. long; stamens 10, equal, the linear- 

 oblong filaments pilose-ciliate for the upper half of their length, 4 mm. 

 long, the densely muriculate anther sacs 6 mm. long, the tubules 2, connate,
