Mr. Popenoe describes this species as a very common shrub on the slopes 

 of Mt. Tunguragua between the altitudes above mentioned, with very juicy, 

 tender and crisp, pleasantly subacid berries which resemble large pearls in 

 appearance. The native name of the plant is "chirimote." It is allied 

 to D. weberbaueri Horold, of Peru, which is described as a shrub only 0.5 

 meter high, with white corolla, filaments 4 mm. long, and anthers 3 mm. 

 long (body 2 mm., tubules 1 mm.).' 



Disterigma popenoe! Blake, sp. nov. 



Shrub 2 m. high; branches whitish, becoming purplish brown, glutinous, 

 puberulous, glabrate, leafy; petioles stout, puberulous, 2 to 4 mm. long; 

 leaf blades oval or elliptic-ovate, 2.4 to 3.4 cm. long, 1.2 to 2 cm. wide, 

 acute to obtuse, cuneate at base, coriaceous, entire, glabrous, strongly 3- 

 nerved from the base, the nerves impressed above, prominent beneath, 

 usually evanescent below apex of leaf, the secondaries obscure or obsolete; 

 flowers in dense axillary fascicles of about 6, sessile or on pedicels 1.5 mm. 

 long or less ; bractlets 2 at ba.se of calyx, equaling calyx tube, suborbicular, 

 2 mm. long, ciliolate with subglandular hairs; calyx tube campanulate- 

 subglobose, obtusely quadrangular, glabrous, equaling the limb (1.5 mm. 

 long), the 4 deltoid acutish teeth glabrous or slightly ciliate; corolla 

 "white," cylindric, 6 to 7 mm. long (with teeth straightened out), the tube 

 rather densely spreading-puberulous outside, pilose-barbate within except 

 at base, the 4 recurved lobes triangular-ovate, glabrous, about 2.2 mm. 

 long; stamens 8, the filaments linear, pilose on both sides except toward the 

 glabrous base, 5 mm. long, the anther sacs 1 mm. long, the tubes 2 mm. long, 

 conic; ovary 4-celled; "berry translucent white, about 6 mm. thick." 



Type in the U. S. National Herbarium, no. 1059983, collected in very 

 moist scrub in the Cordillera de Zamora, east of Loja, Ecuador, altitude 

 2440-2475 meters, April 11, 1921, by Wilson Popenoe (no. 1323). 



This species, which occurs abundantly in cool and moist places in the 

 Cordillera of Zamora between 2440 and 2745 meters, bears the native name 

 "tira, " which seems to be restricted to it. The fruit is said to be similar 

 to that of the "chirimote" (Disterigma margaricoccum, described above), 

 but is not quite as good. The species is very distinct from any previously 

 described in its comparatively large strongly 3-nerved leaves and numerous 

 flowers with the corolla densely puberulous outside. 



Macleania irazuensis Blake, sp. nov. 



Shrub 2 m. high; branch stout, sub terete, glabrous; petioles stout, 

 glabrous, 5 mm. long; leaf blades elliptic-ovate, 4 to 6 cm. long, 2 to 2.6 

 cm. wide, obtuse, broadly rounded or subcordate at base, entire, coriaceous, 

 glabrous, marginate, penninerved, the lateral veins 4 or 5 pairs, sparsely 

 branched, obscure or prominulous above, prominulous beneath; racemes 

 axillary and terminal, 1.5 to 3.8 cm. long, glabrous, erect, straight, becom- 

 ing loosely flowered in age, about 10-flowered, the bracts ovate, rounded, 



il take this opportunity to transfer to Disteribma a Costa Rican species of this genus 

 described under Vaccitiium several years ago.
