126 The Philippine Journal of Science me 



This species has previously been reported from the Philippines as 

 Ampelocissus imperialis Planch., but that identification was certainly 

 erroneous, although manifestly Ampelocissus ochracea and A. imperialis 

 are closely allied. There is now a specimen in the herbarium of the 

 Bureau of Science collected in Sumatra by Teysmann, manifestly a 

 cotype of Ampelocissus imperialis (Miq.) Planch., which differs from our 

 Philippine material in its larger, more numerously nerved leaves, and 

 especially in the basal lobes of the leaves overlapping. Planchon has 

 reduced "Vitis ochracea Teysm." to Ampelocissus imperialis, but from 

 his citation it is evident that he did not see the published description of 

 Cissus ochracea T. & B. The type of Teysmann's species was from Celebes, 

 a plant cultivated in the Botanical Garden at Buitenzorg, and his descrip- 

 tion appears to me to apply to our Philippine form and not to Ampelocissus 

 imperialis Planch. I have accordingly reinstated Teysmann's species, and 

 transferred it to its proper genus, Ampelocissus.

 (1887) 413; Gagnep. in Bull. Soc. Hist. Nat. Autun 24 (1911) 20. 

 This characteristic endemic species was based on a specimen collected 

 by Cuming in the vicinity of Mount Banahao, Luzon, distributed as num- 

 ber 820 of Cuming's Philippine collection, but until recently has not been 

 rediscovered. Additional specimens, all from the Province of Laguna, 

 Luzon, are as follows: near Paete, Baker S695; Lilio, Gates 6471 coll. 

 Quisumbing ; San Antonio, Bur. of Sci. 10994, 16660 Ramos.

This was previously determined and reported as Ampelocissus barbata 

 Planch., a very closely allied species, but Doctor Gagnepain has recently 

 referred my number 4150 (not 3150 as cited by him) to the Indo-Chinese 

 species A. martini Planch. After a reexamination of our material, the 

 descriptions, and a duplicate of Pierre 1803 from Cochinchina, I agree with 

 Gagnepain's identification of the Philippine specimen. 



AMPELOCISSUS PAUCI FLORA sp. nov. § Euampelo cissus. 



Species ut videtur A. aculeatae et A. acetosae affinis, differt 

 inermibus, omnibus partibus glabris, foliolis oblongo-ovatis ad 

 ovato-lanceolatis, acute acuminatis, inflorescentiis paucifloris. 



A slender, unarmed, scandent vine, entirely glabrous, 6 to 8 m 

 in length, the branches and branchlets terete, brownish or 

 purplish when dry, often glaucescent. Leaves pedately 5- to 

 7-foliolate, their petioles 2 to 2.5 cm long; leaflets submem- 

 branaceous or chartaceous, oblong-ovate to ovate-lanceolate, the 

 outermost lateral ones smaller than the others, 4 to 8 cm long,
