198 GLEASON: CENTROPOGON AND SIPHOCAMPYLUS 
25. SIPHOCAMPYLUS ANGUSTIFLORUS Schlecht.; Lechler, PI. 
Lechler. Peruv. 2649. 
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. 2 
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, 
0-60 mm. long, 15-22 mm. wide, sharply serrulate, glabrous and 
chicane 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. long by 25-35 mm. wide; inflorescence secund, the 
pedicels 10 mm. long or less; flowers deflexed; hypanthium thinly 
pubescent, turbinate or obconic, 4 mm. high; sepals triangular, 
I 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. 
B. 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 makers 
1. Sepals linear to linear-oblong, prominently refi harply 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. 
The single specimen examined, Mandon 498, does not agree
