NEW rillLIl'I'INE FLOKA. 423 



Mindanao, Lake Lanao (083 Mrs. Clemens) 8eptember-0ct()l)er, I'JOO. Malay- 

 an Peninsula to Java and Sumatra, and probably other islands in the Malayan 

 Archipelago. 



The specimens from Mindanao are apparently typical, and with the exclusion 

 of K ads II I a hluiwoi^= Phytocrene ! (Icaciyiacew) from the Magnoliciceie, the above 

 species is the first one of the genus to be recorded from the Philippines.

 Prodr. 17 (1873) 20. 



Mindanao, Lake Lanao, Camp Keithley (137 Mrs. Clemens) 1900, in fruit in 

 February, in flower in July and September. 



Baillon gives the distribution of the variety integnfolia=C. moluccana, 

 as from British India through IMalaya to New Guinea, but Engler in Nat. Pflan- 

 zenfamilien gives its distribution as from the Moluccas, Ceram and New Guinea. 

 F.-ViUar reported it from Luzon and Panay, but his record of the species as a 

 Philippine plant has previously never been verified.

Glabra; foliis ovafis vel oblongo-ovatis, membranaceis, 11 ad 20 cm. 

 longis, 6 ad 11 cm. latis, apice acuminatis, basi leviter cordatis, margine 

 grosse distanter sinuato-dentatis ; receptaculo oblongo-lanceolato, longe 

 pedunciilato, 11 ad 20 cm. longo, 1 ad 1.8 cm. lato, floribus marginalibus 

 pedicellatis, floribus sessilibus immersis, -l-meris. 



Nearly glabrous throughout when mature, the younger parts slightly 

 ferruginous-pilose. Branches slender. Leaves ovate to oblong-ovate, 

 simple, 11 to 20 cm. long, 6 to 11 cm. wide, membranaceous, the apex 

 sharply acuminate, the base somewhat cordate, broad, the margins 

 distantly and coarsely sinuate-dentate, dull or shining ; nerves prominent, 

 curved-ascending, about 5 on each side of the midrib ; petioles 3 to 5 

 cm. long. Tendrils bifid. Receptacles red ( ?) apparently somewhat 

 fleshy when fresh, oblong-lanceolate, 11 to 20 cm. long, 1 to 1.8 cm. 

 wide, long pedunculate, the marginal flowers rather numerous, pedicel- 

 late, the pedicels aljout 1.5 cm. long, those on the surface of the lamina 

 sessile, immersed, very numerous, 4-merous, the petals triangular-ovate,

Mindanao, Lake Lanao, Camp Keithley (047 Mrs. Clemens), July-October, 

 1906, four collections. 



The first species of this very characteristic Malayan genus to be found in the 

 Philippines and apparently closely related to Pterisanthes polita Miq., of the 

 Malayan Peninsula, Sumatra and Borneo, differing from that species in its 

 coarsely sinuate-toothed larger leaves and other characters.
