 argyraeus). 



C. A. Backer's No. 23530 from Pasir Pogor (Mt. Salak, Java) and 

 spécimens cultivated in the Buitenzorg Gardens show that the type and 

 Engler's varieties may be found on the same stem. The very broad 

 leaves with a deep-cordate base are of the main stein and the oblong 

 ones with a rounded base are occasionally those of the ultimate branches. 



Spathiphyllum cannifolium (Dry.), Schott, Gen. Aroid., I, tab. 1 ; Engl. 

 & Krause, Pflzrch, XXXVIl (23 B), 132, fig. 55 H -O; Pothos cannaefolia, 

 Dry., in Curt. Bot. Mag., tab. 603. 



Plants, everywhere in Malaya cultivated (and apparently also gone 

 wild) under the name of Sp. cannifolium Schott, are distitîguished from the 

 diagnosis given by Engler and Krause as follows: Pétiole often sheathed 

 to far beyond the middle, sometimes even to the knee and, like the knee 

 and Costa beneath, copiously, conspicuously longitudinally ribbed; spathe 

 often smaller, the inner side white, with fine, often greenish veins and a 

 submarginal collective vein, the outer side green, with darker-green veins; 

 spadix often smaller; perigonium 4 — 6-angular; ovaries with the loculi 

 4-ovulate (see Engler & Krause's fig. 55 /), sometimes 6-ovulate. 



Spathiphyllum commutatum, ScHOTT, Oestr. bot. Wchbl., 7557, 158; 

 Engl. & Krause, Pflzrch, XXXVIl (23 B), Arac.-Monster., 133, fig. 55 ^-G. 



Spécimens occurring in the Buitenzorg Herbarium and plants cultivated 

 in the Buitenzorg Gardens under the name of Sp. commutatum Schott are 

 distinguished from the diagnosis given by Engler and Krause as follows: 

 Pétiole with the sheath not reaching the knee; lamina proportionally nar- 

 rower, + half as broad as long; costa not whitish but distinctly green 

 though paler than the lamina; spathe much smaller, not rarely pale-(greenish-) 

 veined and -margined often on the outer side only, at length becoming 

 quite green; spadix smaller, white, tending towards pale-grey; ovaries 

 with a shortly conical apex, and the loculi 4-ovulate.
