data, and 882, forests of Popayd4n, 1700-2500 m., the leaf-blades 
are more than twice as long as broad and sharply cuneate at 
base and the thinly villous sepals are about 30 mm. long. In 
Pennell and Killtp 8087, Rio Ortega, Dept. El Cauca, Colombia, 
2 July 1922, and Pennell 10,279, Apia, Dept. Caldas, 4,5 Sept. 
1922, the leaf-blades are less than twice as long aS wide and the 
densely villous sepals are only 20 mm. long. Zahlbruckner cited 
two sheets, Lehmann 4754 and Triana 1569. I have seen the 
latter in the herbarium of the Museum at Paris and find it 
essentially intermediate between the two forms mentioned above. 
Centropogon caldasensis n. sp. Stem herbaceous, angled, 
hollow, puberulent above, becoming glabrous below, bearing 
: m. long, con- 
spicuously ridged, thinly puberulent, with two basal linear 
petals; anther-tube strongly depressed, short and stout, 4 mm. 
long, glabrous, the two lower anthers densely villous at the apex. 
Type, Pennell 10,322, collected 7-11 Sept. 1922, along the 
Rio San Rafael, below Cerro Tatama, altitude 2200-2400 m., 
Dept. Caldas, Colombia, and deposited in the herbarium of the 
New York Botanical Garden. 
Centropogon Mutisianus (H.B.K.) n. comb. (Lobelia 
Mutsitana H.B.K.) The distinction between this and related 
species stated in the key above has been drawn from the type 
specimen in the herbarium of the Museum at Paris. 
Centropogon variabilis n. sp. Stem herbaceous, strongly 
angled, densely pubescent or subtomentose with sordid brown 
hairs above, becoming glabrate with age, the internodes 1-2 
cm. long; petioles angled, densely pubescent, 10-25 mm. long; 
leaf-blades broadly elliptic, about 9 by 18 cm., thin and mem-
