and calyx pink-tinged; corolla yellow in bud, at anthesis tinged with pink under 

 the crimson hairs; body of corolla red at about time it is ready to fall, and crimson 

 as it lies on the ground; some plants with flowers redder than others at anthesis). 

 Same locality, on banks of Rio Itzintza, 3,500 ft. elev., Camp E-1199 (high-climbing 

 epiphyte, common in this region but seen only along streams; leaves green above, 

 paler beneath; pedicels and hypanthium crimson; corolla yellow in bud, with 

 crimson hairs, becoming red or even crimson in age, apically constricted; filaments 

 and connectives white, the anthers yellow). 



The excellent series of specimens cited forms a welcome addition to the herbarium 

 material of this species, which otherwise I have known only from southern Colombia 

 (Cauca, El Yalle, Narino, and Putumayo). Dr. Camp's material, of course, demon- 

 strates a few minor variations from the original description, but the fundamental 

 characters of the species are unmistakable. 



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



Pichincha: Western slope of the cordillera, Cerro Corazon, 8,000-9,300 ft. 

 elev., Camp E-1680 (vine-like epiphyte; leaves pale green and dull above, paler 

 but subnitid beneath; pedicel basally greenish, apically bright coral-red; hypan- 

 thium bright coral-red at anthesis, the color fading to dark green as the fruit 

 enlarges; corolla deep red toward base, pale green in upper half; flowering irreg- 

 ular, sometimes at apex of stem, or later on nearly bare wood). Along the road from 

 Quito to Sto. Domingo de los Colorados, 7,000-8,500 ft. elev., Camp E-1728 (NY 

 only) (shrub 3 m.; leaves pale green and dull above, subnitid beneath; hypanthium 

 pale coral-red; base of corolla deep crimson, the apex green). 



The cited specimens are very typical of the species, which is known from 

 several collections from Pichincha and extends northward into Narino. Sleumer 

 inadvertently omitted this species from his review of the Psammis'iae with pinnati- 

 nerved leaves (Bot. Jahrb. 71: 403-404. 1941). 



Psammisia oreogenes Sleumer, Bot. Jahrb. 71: 403. 1941. 



Pichincha: Western slope of the cordillera, Cerro Corazon, 8,000-9,300 ft. 

 elev., Camp E-1677 (vine-like epiphyte; leaves deep green above, pale beneath; 

 at anthesis peduncles deep coral-red and hypanthium pale coral, deeply grooved; 

 base of corolla red, white toward the end, the apex green; bracts and pedicels 

 green; flowers in axils of leaves), Camp E-1678 (NY only) (epiphytic vine, with 

 flowers on old wood; pedicels deep coral-red, the bracts green; hypanthium pale 

 yellowish coral; lower part of corolla red, the apex green, without white zone noted 

 in no. 2677 but in same stage, the corolla much broader). 



In foliage these two specimens appear conspecific, but unfortunately the 

 flowers described for no. 1678 have been lost. Differences can be observed between 

 these plants and the description of P. oreogenes, typified by Heilborn 488 , also 

 from Pichincha. Dr. Camp's specimens have the petioles slightly longer, the pedi- 

 cels shorter, more slender, and glandular-pilose distally rather than glabrous, the 

 calyx glandular-strigillose rather than glabrous, the stamens somewhat longer 

 (about 9 mm. long), and the anther- tubules about 5 mm. rather than 2.5-3 mm. long. 

 Our specimens differ from the allied P. sodiroi in the merely apiculate calyx- 

 limb, the longer corolla, and in details of venation, in which characters they 

 seem to agree with Sleumer 's species.
