Loja: "Oriente" Border, crest of the Cordillera de Zamora, east of Loja, ca. 

 10,000 ft. dev., July 2, 1944, Camp E-106 (TYPE US 1,988,934; dupl. NY) (stiff 

 shrub 3 m. high; leaves dull on both surfaces; calyx conspicuously fluted; corolla 

 carnose, deeply grooved, red, apically tinged with yellow). Nudo de Guagrauma, ca. 

 12 km. south of Zaraguro, 9,500-10,500 ft. dev., Camp E-134 (NY only) (climbing 

 epiphyte in sotobosque; flowers pendulous; calyx angled; corolla angled, pale 

 crimson, the tip greenish yellow). 



The two cited specimens agree very closely in fundamental details, but no. 

 134 has somewhat the narrower leaves and the larger flowers. The floral dimensions 

 are probably a matter of age; in the description the larger dimensions are probably 

 to be taken as representative of the floral measurements at anthesis. 



The new species superficially resembles C. nubigenum, differing, as noted in 

 my key, in its villose flowers, its angled calyx-tube and corolla, the absence of 

 marginal calycine glands, its free filaments, and the differently proportioned anther- 

 thecae and -tubules. 



Ceratostema charianthum A. C. Smith, Contr. U. S. Nat. Herb. 29: 360. 1950. 



Santiago-Zamora: Cordillera Cutucu, ridge just south and west of Rio Itzintza, 

 4,500-5,500 ft. dev., Camp E-1334 (NY only). Eastern slope and crest of main 

 Cordillera Cutucu, 5,600 ft. dev., Jorgensen CuJ-44 (NY only). Eastern slopes of 

 the cordillera, near junction of Rios Pailas and Negro, 6,000-7,500 ft. dev., Camp 

 E-4932 (coll. F. Prieto). 



Field notes describe the species as a weak epiphyte or a vine growing on mossy 

 banks or climbing trees in mossy forest, with adventitious roots which become en- 

 larged and tuberous near the stem; leaves deep green above, paler beneath, dull on 

 both sides; calyx pinkish; corolla bright rosy pink to pale crimson. 



The three cited specimens are welcome additions to the material of the species, 

 otherwise known only from the type, obtained in the same general region. Slight
