ACANTHOPHORA SCANDENS sp. nov. 
Frutex scandens, ramis et paniculis et foliis ad petiolo rhachi- 
busque primariis et secundariis et'ad costa subtus spinis numero- 
sis parvis recurvatis armatis; foliis amplis, tripinnatis, usque 
ad 1.5 m longis; foliolis numerosis, ovatis ad ovato-lanceolatis, 
acuminatis, submembranaceis, 7 ad 14 cm longis, basi rotundatis 
vel subcordatis, margine spinuloso-dentatis ; paniculis terminali- 
bus, amplis, usque ad 1 m longis; umbellulis numerosis, circiter 
20-floris, pedunculatis ; floribus 5- vel 6-meris, petalis imbricatis. 
A scandent, sparingly branched, aculeate vine, sprawling over 
thickets, the stems about 2.5 cm in diameter, these, the petioles, 
primary and secondary leaf-rachises, petiolules, midribs of the 
leaflets beneath, and the inflorescences armed with short, stout, 
sharp, scattered but numerous, recurved spines, otherwise 
entirely glabrous. Leaves alternate, 1 to 1.5 cm long, triangular 
in outline, at least tripinnate, the lower primary pinnae long, 
the upper ones gradually shorter; petioles stout, aculeate, the 
lower 6 to 8 cm split on the upper side and with 1 cm wide 
wings (stipules) which surround the stem at the base, the lower 
ultimate divisions of the leaf odd-pinnate, the upper ones trifo- 
liolate. Leaflets ovate to elliptic-ovate or ovate-lanceolate, sub- 
membranaceous, 7 to 14 cm long, 3 to 5 cm wide, the apex 
strongly acuminate, the base broad, rounded or subcordate, the 
margins rather finely spinulose-denticulate, glabrous and some- 
what shining, the midrib beneath and more rarely also on the 
upper surface with few, scattered, recurved spines; nerves 5 to 
7 on each side of the midrib, rather prominent, anastomosing; 
petiolules 3 to 10 mm long. Panicles terminal, ample, pinnately 
compound, up to about 1 m in length, the branches alternate, 
opposite, or somewhat whorled, the primary ones up to 40 cm 
in length. Umbels numerous, racemosely arranged on the ulti- 
mate branchlets, each about 20-flowered, their peduncles 1 to
