An aquatic glabrous plant. Leaves tufted, their petioles 10 to 25 em 

 long, the blades reniform, 4.5 to G cm long, about 8 cm wide, papyraceous, 

 the apex broadly rounded, the base cordate; primary nerves 7 to 9, the 

 cross reticulations lax, indistinct. Male flowers one, or commonly two, 

 from tubular, linear spathes which are very slightly cleft at the apex 

 and not keeled or ribbed, exserted in anthesis, the pedicels very slender: 

 sepals and petals as in the pistillate flowers; stamens 9. the filaments 

 flattened, 1.5 to 2 mm long; anthers basifixed, oblong, 1.5 mm long; 

 rudimentary pistil represented by a sessile, 1.5 mm long, cushion-like 

 body, the styles none. Pistillate flowers white, solitary, their pedicels 

 5 cm long or less; sepals 3, elliptic-oblong, about 7 mm long, 3.5 to 4 

 mm wide, about 12-nerved; petals obovate, 12 mm long; styles 6, cleft 

 two-thirds to the base, the arms glandular-hairy; staminodes of two 

 kinds, G linear, 2.5 to 3 mm long, and 3 subsessile, capitate, 1 mm in

An interesting addition to our knowledge of the Philippine flora, tlie first 

 representative of the genus to he found in the Philippines. It is allied to Boottia 

 cordata Wall., of British India, hut differs in many characters, notably in its 

 reniform leaves, linear, tubular spathes which contain hut one or two flowers, the 

 Staminate flowers without rudimentary styles, and the pistillate ilowers with two 

 kinds of staminodes, six linear and three capitate. The genus contains about 15 

 species, in tropical Africa and Asia.

Hooker f. 1 referred Poa malabarica Linn, to Gentotheca lappacea (Linn.) Desv., 

 hut gave no reason for this. Considering that he was correct I transferred the 

 name to Gentotheca as C. malabarica (Linn.) ]\lerr. It seems, however, that 

 Hooker f. was in error in citing Poa malabarica Linn, as a synonym of Cento- 

 theea lappacea. Munro in his paper on the grasses of the Linnean herbarium 

 states regarding Poa malabarica "P(oa) malabarica is Panicum amottianum 

 Xces. The reference to Rheede is correct; it is a very fair drawing." 2 Linnaeus' 

 species is manifestly based on Tsjama-pullu of Rheede, Hortus Malabaricus 12:83, 

 t. 45. Through the kindness of Mrs. Agnes Chase of the United States Depart- 

 ment of Agriculture, I have received a tracing of the above plate, and although 

 the plate is crude, it seems to be well matched by several specimens in our her- 

 barium determined as Panicum nodosum Kunth. Three specimens from Singa- 

 pore, collected by Ridley resemble it very closely.
