Colombia, Barbacoas : Triana 1660 ! 



A striking species, with shining leaves 9-15 cm. x 4-7 cm., Avith 

 stalks up to 15 mm. in length. The stipules sheathe to a height of 

 about 3 mm., bearing two sharp prongs on eadh side of the stem, each 

 about 3 mm. long. The whole injlorescence, a pyramid up to 10 cm. 

 or longer and the same width at the base, is carried on 2^. peduncle 

 9 cm. or more in length ; the primary" lateral branches of the main 

 j-acliis are bare, and some 2 cm. to 3 cm. long; and these bear 

 laterally the ])eduncles of the actual cymules, the nnits of this charac- 

 teristic inflorescence ; these ])eduncles are 1 cm. or longer, and are 

 themselves sometimes branclied. The cymule, the unit of inflor- 

 escence, consists of 6 to 12 sessile flowers seated on the somewhat 

 enlarged apex of the peduncle and subtended by a minute involucre 

 of sej)al-like bracts. The few scattered bracts of the inflorescence- 

 branches never exceed 2 or 3 mm. in length. The whole Cf^/y.r bareh^ 

 exceeds 1 mm.; coro//«-tube, 3 mm., lobes 1*5 to 2 mm. Anthers 

 2 mm. lon<
