Macleania coccoloboides A. C. Smith, sp. nov. 



Frutex ad 3 m. altus vel epiphyticus et subscandens ubique praeter ramulos 

 et petiolos glaber, raraulis robustis subteretibus nigrescentibus primo et petiolis

Pichincha: Western slope of the cordillera, along the road from Quito to Sto. 

 Domingo de los Colorados, 7,000-8,500 ft. elev., Jan. 15, 1945, Camp E-1726A 

 (TYPE US 1,989,052; dupl. NY) (shrub 1-3 m., arching from banks, arising from a 

 burl up to 0.3 m. in diameter, also seen as a high-growing epiphyte and then also 

 with burl; branches sooty-black; leaves very deep green above, pale to subglaucous 

 beneath, with glands at first black and later conspicuous by the presence of a 

 white fungus; hypanthium pale yellow to red, very shallowly grooved, the calyx 

 margin and sometimes the base with notable pits; corolla deep crimson; fruit rip- 

 ening deep purple-black, shining), E-1726B (NY only) (young plant of no. 1726A, 

 showing the burl, this soft-parenchymatous, not woody). Same general locality, 

 Cerro Corazon, 8,000-9,300 ft. elev., Camp E-1679 (NY only) (epiphytic and vine- 

 like; twigs dark, blackish; leaves exceptionally dark green above, pale and glaucous 

 beneath; immature fruits pale, subtranslucent). 



This new species is readily distinguished by its comparatively short corollas 

 and anthers abruptly terminating in very short, slender tubules. It does not seem 

 to have very close allies, but in some ways it suggests M. costeroides Sleumer 

 (Bot. Jahrb. 71: 401. 1941), also of Ecuador. From this, M. coccoloboides differs 

 in its larger leaf-blades with more highly connate nerves, its very short inflores- 

 cences, minutely denticulate calyx-limb, longer corolla, and stamens with free 

 filaments and separate tubules. 



Psammisia corallina A. C. Smith, sp. nov. 



Frutex epiphyticus ubique glaber; ramulis robustis obtuse angulatis in sicco 

 striatis fuscis; petiolis valde rugulosis angulatis incrassatis 10-12 mm. longis;
