 ginous-liirsute on the midrib l)eneath or quite glabrous; nerves 4 to 5 

 on each side of the midrib ; petioles 1 em. long or less, ferruginous- 

 hirsute. Flowers axillary, solitary, loug-pedicelled, about 1.5 cm. long, 

 the pedicels sparingly hirsute. 1 to 2 cm. long, slender, biI)racteohite at 

 about the middle, the bracts narrow, '2 mm. long or less. Calyx glabrous 

 or nearly so, the tube broad, about 3 mm. long, the teeth about 4 mm. 

 long, broadened at the base, narrowed abruptly and linear-lanceolate 

 al)ove, persistent and slightly accrescent in fruit. Corolla about 1.5 cm.

In forests at l.SOO in. alt. (Nos. 5718, 5777). The same species, but with 

 shorter petioles and somewhat narrower leaves has been collected on Mount Ma- 

 lindang, ^Mindanao, at an altitude of 1,700 m. (No. 4753 Mearns and Hutchinson) 

 May, 1!J0(). A sterile specimen from Canlaon Volcano, Negros, collected by Banks 

 in ]\Iarcli, 1902. witli mure strongly sinuate leaves is probably referable here.

In forests at 1)00 m. alt. (No. 4.S50 Jlrrritt) June, lOOG. 



A characteristic, ai)parently undescribed species, with very long petioles, but

Cyrtandra sp. 



In forests at 1.400 m. alt. (No. 5770), an underslirnb 1 to 1.5 m. high.
