4,500-5,500 ft. elev. , Camp E-1333 (NY only) (high-growing epiphyte; corollas 

 found on ground, crimson, the lobes purple-black). 



Of the cited specimens, no. 1333 consists only of fallen corollas, but it may 

 confidently be referred to this species. The other two specimens show some foliar 

 variability, the leaf-blades of no. CuJ-39 tending to be more ovate and broader 

 than those of the type, with rounded rather than obtuse bases. In inflorescence 

 characters the two specimens are essentially identical, except that No. CuJ-39 

 has bracts and bracteoles without the marginal glands which occur on the type; 

 both specimens usually have a dorsal gland on each calyx-lobe of a very char- 

 acteristic type. 



Ceratostema ventricosum, although a very distinct species, has characteristics 

 suggestive of several of its allies. Its leaves and inflorescences resemble those 

 of C. prietoi, described below, but the calyx-limb is strikingly different, the 

 corolla is more obviously ventricose, and the anther-proportions are different. In 

 its calyx the new species resembles C. lorantbiflorum, but that species has the 

 calyx-articulation obscure or lacking, the corolla and stamens much shorter, and 

 the leaves very different. From C. calycinum, which it resembles somewhat in 

 foliage, C. ventricosum differs in its smooth calyx-tube and much shorter and 

 differently shaped lobes, its more strongly ventricose corolla, and its longer 

 filaments.

Azuay: Paramo and sub-paramo area north and northwest of the Paramo del 

 Castillo (ca. 6-8 km. n.-ne. of Sevilla de Oro), 10,000-11,200 ft. elev., Camp 

 E-5153. "Oriente" Border, Eastern Cordillera, between Ona and the RioYacuambi, 

 on crest,- 10,000-11,200 ft. elev., P. Prieto P-295. "Oriente" Border, Paramo del 

 Castillo and surrounding forested areas (crest of the eastern cordillera on the 

 trail between Sevilla de Oro and Mendez), 9,000-11,000 ft. elev., Camp E-700, 

 E-746; same locality, 11,000-11,300 ft. elev., Camp E-4867; same locality, east 

 of El Pan, 11,000-11,350 ft. elev., Camp E-1626. 



Field notes indicate the plant as a low shrub, up to 3 m. high in sheltered 

 places; leaves dark green and shining above, pale and dull beneath; pedicels and 

 hypanthium deep crimson or red; corolla deep crimson at base, shading to purple 

 or black at tips of lobes; filaments pink; anthers brown; ripe fruit oblate-spheroid, 

 up to 1.5 cm. long and 2 cm. in diameter, dull reddish, nitid, slightly sweet. 



The excellent series of specimens cited above nearly doubles the number of 

 collections known for this species, but the variation does not notably extend the 

 limits of my earlier description (as Englerodoxa alata Hoer. in Contr. U. S. Nat. Herb. 

 28: 350. 1932). The leaves are sometimes up to 3 cm. broad and the corolla may 

 be as short as 35 mm. at anthesis, although more often it exceeds 40 mm. in 

 length. Since my 1932 treatment the following collections have been noted: Prov- 

 ince of Pichincha, Acosta-Solis 8304 (Ch,,US); Tungurahua, Penland & Summers 

 310 (NY); Santiago-Zamora, Steyermark 54333 (Ch). 



Ceratostema nubigenum (A. C. Smith) A. C. Smith, comb. nov. 



Periclesia nubigena A. C. Smith, Contr. U. S. Nat. Herb. 29: 366. 1950. 



This is another species which, because of its connate filaments, I originally 

 referred to Periclesia. Although, as originally noted, it has certain features sug- 

 gestive of Periclesia pensilis (e. g. Ceratostema p.), it is a very distinct species 

 closely related only to the following new entity. 



Ceratostema campii A. C. Smith, sp. nov.
