Homalomena latifrons, EnGL , Pflzrch, LV (IV, 23 Da), Arac.-Philod.- 

 Homal.-Schism., 54, fig. 30. 



Hallier's original Nos. 68 and 1357, on which Engler based this 

 species, are distinguished from his diagnosis by the following characters: 

 Pétiole to nearly 2'/2 X as long as the lamina, 25— 47'/2 cm. long, sheathing 

 \j^ — ij^ its length; lamina broadly triangular-cordate, tending towards 

 sagittate, IT'/z — 25 X 17—24 cm., with the posterior lobes '/4— V2 3sIong 

 as the central lobe; peduncles 5— 12'/2 cm. long; spathe 4— ô'/a cm. long; 

 spadix on a stalk about 5 mm. long (not hardly stalked), about as long as 

 the spathe (including the stalk); masculine inflorescence about l'/2— 2 X^s 

 long as the féminine. 



A spécimen from an unknown locality, cultivated in the Buitenzorg 

 Gardens, determined bij ENGLER, is distinguished in having the ovaries very 

 pale-green, the staminodes white, the masculine inflorescence greenish- or 

 yellowish-white.
