deltoideis apiculatis 0.5-1 mm. longis, sinibus rotundatis; disco annulari-pulvinato 

 glabro; corolla glabra tenuiter carnosa late urceolata circiter 7 mm. longa et 

 medium versus 4.5 mm. diametro, basi et apice paullo angustata, lobis 5 deltoideis 

 subacutis circiter 1.5 x 2 mm. sub anthesi reflexis; staminibus 10 longitudine 

 corollam fere aequantibus leviter inaequalibus, filamentis pallidis ligulatis liberis 

 alternatim circiter 1.5 mm. et 1.8 mm. longis superne pilis circiter 0.5 mm. longis 

 dorso hispidulis, antheris 4.5-5 mm. longis, thecis granulatis 1.7-2 mm. longis 

 basi obscure mucronulatis, tubulis gracillimis quam thecis longioribus et multo 

 angustioribus per rimas circiter 0.5 mm. longas dehiscentibus; stylo tereti corollam

Chimborazo: Canon of the Rio Chanchan, about 5 km. north of Huigra, 5,000- 

 6,500 ft. elev. (moist forested valleys in the afternoon fog-belt), May 19-28, 1945, 

 Camp E-3363 (TYPE US 1,989,082; dupl. NY) (hanging epiphyte; leaves crisp- 

 succulent, to 4 mm. thick, dark translucent-green, inflated above, pale below with 

 stomata, the surface with numerous pits, the bases of glands; lower % of the leaf 

 in cross-section with chlorenchyma, the upper % with apparently 4 cell-layers of 

 hydrenchyma; corolla cream-white, the anthers orange). 



This very distinct species is most closely allied to the Colombian T. rostrata 

 A. C. Smith, from which it differs in having its leaf-blades somewhat smaller, 

 narrower at base, thicker and inflated when fresh, and with immersed venation 

 and gland-hairs sunk in small pits on the lower surface. The new species is 

 further distinguished by its very slender anther- tubules, which are not charac- 

 teristic of Themistoclesia. Slender tubules of this type have been noted in the 

 Colombian T. crassifolia Sleumer (Bot. Jahrb. 71: 392. 1941), to which T. inflata 

 is also allied. However, T. crassifolia has much larger and obviously cordate 

 leaf-blades and an elongate inflorescence, among other characters which dis- 

 tinguish it from the new species.
