escent, subtended by similarly hairy caducous bracts; calyx, 

 segment 3, pale green, ovately elliptic to oblong, 1 cm. long, 

 6 ram. wide, coriaceous, united toward the base, velvety to- 

 mentulose except the inner basal portion, the acute to acu-

 thickly coriaceous, greenish yellow, 1.5 cm. long, 1.25 cm. 

 wide across the middle or across the widest portion, elliptic, 

 shining velvety appressed puberulent except the upper basal 

 portion which forms a ring of pouch over the sex organs, 

 imbricate, the inner 3 slightly shorter and more constricted 

 toward the arched basal portion; receptacle flattened, glabrous 

 except the imbricate border; stamens numerous, imbricate, 

 yellowish, 1.5 ram. long, short stipitate and usually subtend-

Type specimen number 13608, A. D. E. Elmer, Cabadb.i- 

 ran (Mt. Urdaneta), Province of Agusan, Mindanao, August, 1912. 



Collected in moist rocky soil of a humid wooded depres- 

 sion at 3750 feet altitude, between the peaks of Duros and 

 Cawilanan. The natives or Manobos call it "Cabak-cabak." 



Most closely related to A. cumingiana glabra Elm. but 

 our leaves are smaller, more acuminate and much more re- 

 ticulately nerved. 



Artabotrys vidaliana Elm. n. sp. 



A looping climber and sprawling over woods; main branch- 

 es long, repeatedly rebranched, hanging from the tops of 

 trees over the river; stem terete or nearly so, -5 cm. thick, 

 bendable, porous, with fine rays, odorless and tasteless; bark 

 brown, scaling in very small scales, deeper brown on the 

 inner side; the ultimate branches relatively short and di- 

 varicately disposed, very tough, the brown young portion gla- 

 brous. Leaves horizontal, recurved especially the abruptly 

 acute or obtusely pointed apex, base broadly obtuse, the 

 entire margins subinvolute in the dry state, curing isabellinus 

 on both sides, glabrous, alternatingly scattered along the twigs.
