198 Gleason: Centropogon and Siphocampylus 



25. Siphocampylus angustiflorus Schlecht.; Lechler, PI. 



Lechler. Peruv. 264Q. 

 Specimens of this species have not been seen: the distinction 

 between it and the following are taken from Zahlbruckner. 



b. Hypanthium pubescent; leaf-blades flat. 



26. Siphocampylus flagelliformis A. Zahlb. Bull. Torrey 



Club 24: 380. 1897. 

 Siphocampylus angustiflorus Britton, Bull. Torrey Club 19: 



372. 1892; not S. angustiflorus Schlecht. 

 Leaf-blades lanceolate or narrowly elliptic-ovate, acuminate, 

 40-60 mm. long, 15-22 mm. wide, sharply serrulate, glabrous and 

 conspicuously veiny beneath. 



27. Siphocampylus altiscandens sp. nov. 



Stems puberulent, climbing 40 feet high on trees; leaves rather 

 crowded, the blades flat, firm in texture, ovate-oblong, acute or 

 subacuminate, entire or remotely and minutely serrulate, almost 

 glabrous above, minutely puberulent beneath, the larger ones 

 60-75 mm - l° n g by 2 5~35 mm - wide; inflorescence secund, the 

 pedicels 10 mm. long or less; flowers deflexed; hypanthium thinly 

 pubescent, turbinate or obconic, 4 mm. high; sepals triangular, 

 1 mm. long, with recurved tips; corolla rose-color, 30-35 mm. long, 

 its lobes linear, erect or spreading; filaments about equaling the 

 petals; anthers glabrous below, all more or less hirsute at the tip. 



Type, Bang 2553, collected at Uchimachi, Corvico, Bolivia, 

 July 20, 1894, and deposited in the herbarium of Columbia Uni- 

 versity. His field notes state that it grows in damp forests and 

 that only two plants were seen, from which forty specimens were 

 collected. It is sharply distinguished from the preceding species 

 by its leaf characters. 



13. Hypanthium very small in proportion to the flower and the ovary mainly free; 

 corolla scarlet, 6-7 cm. long; leaf-blades of a lanceolate or ovate type; sepals 

 usually serrulate; stems climbing: anther-tube glabrous. 

 I. Sepals linear to linear-oblong, prominently reflexed; leaves sharply acuminate. 



28. Siphocampylus elegans Planch. Flore des Serres 6: 19. 



1850. 

 Leaf-blades thick and firm, elongate-lanceolate, rounded or 

 truncate at base. 



Siphocampylus elegans boliviensis A. Zahlb. Bull. Torrey 



Club 24: 381. 1897.
