MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [ Vol. 8, No. 1 



Psammisia guianensis Kl. Linnaea 24: 43. 1851'. 



Napo-Pastaza: Valley of the Rio Pastaza and adjacent uplands, Shell Mera 

 (east of Mera), about 3,500 ft. elev., Camp E-1703 (in swampy areas, often epi- 

 phytic, with arching branches to 3 m. long; inflorescences coral-red, the young 

 corolla white). Santiago-Zamora: Valley of the Rio Zamora, east of Loja, ridge 

 across river from the village of Zamora, about 6,500 ft. elev., Camp E-31 (NY 

 only) (shrub sprawling over rocks). Uplands along Rio Upano just north of junction 

 with Rio Chupianza, near Mendez, 1,750-2,500 ft. elev., Camp E-1004 (NY only) 

 (shrubs on ground or on rotting logs, arching to 3 m.). Eastern slope of the Cor- 

 dillera, valley of the RIos Negro and Chupianza (on the trail from Sevilla de Oro 

 to Mendez), El Partidero, between the RIos Paute and Negro, 2,100-3,100 ft. 

 elev., Camp E-1522 (large epiphytic vine, the branches to 6 m.; leaves deep green 

 above, pale beneath; pedicel, hypanthium, and lower part of corolla deep coral-red, 

 the tip of corolla above constricted part white; filaments and connectives white; 

 anthers brown; immature fruit non-glaucous). 



The cited specimens agree excellently with other material representing this 

 widespread species from the eastern slopes of the Andes. 



Psammisia ulbrichiana Hoer. Bot. Jahrb. 42: 306. 1909. 



Azuay: The eastern cordillera, 1-8 km. north of the village of Sevilla de Oro, 

 8,000-9,000 ft. elev., Camp E-4367 (spreading shrub, the branches ultimately 

 vine-like, to 5 m. long; leaves dark green and subnitid above, pale beneath; im- 

 mature fruit pale salmon), Camp E-4402 (vine; leaves deep green and nitid above, 

 pale beneath; immature fruit pale salmon). Santiago-Zamora: Cordillera Cutucu, 

 ridge ascending into central Cutucu, 3,500 ft. elev., Camp E-1102 (NY only) (high- 

 growing epiphyte, the branches arched to 2 m.; leaves deep green above, pale be- 

 neath). Same locality, ridge between RIos Itzintza and Chupiasa, 4,000-4,500 ft. 

 elev., Camp E-1271 (coarse climbing epiphyte, with branches to 5 m. long). 



The cited specimens are all in fruit, but the comparativeJy large leaves, short 

 inflorescences with congested floral scars, and calycine characters point to their 

 position in P. ulbrichiana, typified by a specimen from the Province of Pichincha. 



Psammisia sp. 



Napo-Pastaza: Valley of the Rio Pastaza and adjacent uplands, Rio Tigre, 

 near junction with the Pastaza (below Topo), 5,400 ft. elev., Camp E-1693 (epi- 

 phyte with branches 5 m. long). 



In the shape and texture of its leaves, the cited specimen suggests P. pauciflora 

 Griseb. ex A. C. Smith, but its persistent calyx-lobes in fruit are rather large for 

 that species. Flowers are needed satisfactorily to place the specimen. 



Calopteryx sessiliflora A. C. Smith, sp. nov. 



Frutex, ramulis fuscis obtuse angulatis pallide puberulis mox glabratis; stipu- 

 lis intrapetiolaribus ianceolato-subulatis circiter 7 mm. longis caducis; laminis e 

 ramulis brevibus lateralibus interdum orientibus, ramulis bracteis papyraceis 

 lineari-lanceolatis ad 15 x .2 mm. circumdatis; petiolis incrassatis subteretibus 

 subglabris 5-12 mm. longis; laminis papyraceis in sicco fusco-olivaceis anguste 

 lanceolatis, 13-28 cm. longis, 3.5-7.5 cm. latis, basi late obtusis, in apicem 

 1-2 cm. longum gradatim *angustatis, subtus pilis glandulosis fusco-castaneis 

 0.2-0.3 mm. longis copiose strigillosis, supra mox glabratis, 5-7-nerviis, nervis 

 secundariis adscendentibus cum costa 2-7 cm. concurrentibus ut costa supra im- 

 pressis (vel basim versus leviter elevatis) subtus prominentibus, rete venularum 

 supra subimmerso subtus prominulo; inflorescentia ramulis defoliatis enata sub- 

 fasciculata ut videtur 1- vel 2-flora bracteis numerosis circumdata, bracteis lineari-
