CONVOLVULACEAE 
ERYCIBE HAINANENSIS sp. nov. 
Frutex scandens, circiter 10 m altus, ramis teretibus, circiter 
5 mm diametro, dense castaneo-villosis; foliis chartaceis ad 
subcoriaceis, ellipticis ad oblongo-ellipticis, 15 ad 18 cm longis, 
6 ad 8 cm latis, perspicue acuminatis, basi obtusis ad subro- 
tundatis, utrinque subconcoloribus, pallide olivaceis, nitidis, 
supra glabris, puncticulatis, costa impressa, subtus ad costa 
dense ferrugineo-villosis ceteroquin leviter villosis, nervis utrin- 
que circiter 9, reticulis laxis, vix conspicuis; petiolo densissime 
villoso, circiter 1 cm longo; inflorescentiis subracemosis, axilla- 
ribus terminalibusque, densissime ferrugineo-villosis, usque ad 
12 cm longis; fructibus ellipsoideis, glabris, circiter 2 cm longis, 
in siccitate nigris, sepalis persistentibus orbiculari-reniformibus, 
ferrugineo-villosis, 3 ad 3.5 mm diametro, margine ciliatis. 
Ng Chi Leng, McClure 8547, December 20, 1921. On forested 
slopes, altitude about 700 meters. 
This is not referable to any of the forms hitherto described 
from or accredited to China, and does not conform with the 
characters of any of the species of Indo-China. It probably 
belongs in the group with E'rycibe magnifica Prain of the Malay 
Peninsula, although it is very different from that species. 
BIGNONIACEAE 
RADERMACHERA HAINANENSIS sp. nov. 
Arbor glabra, ramis ramulisque griseis, rugosis; foliis pin- 
natis, 5-foliolatis, circiter 10 cm longis, foliolis chartaceis, 
oblongo-ovatis, 4 ad 6.5 cm longis, tenuiter acuminatis, utrinque 
minutissime puncticulatis, nervis tenuibus, utrinque 5 vel 6; 
inflorescentiis axillaribus, paucifloris, racemosis vel depauperato- 
paniculatis, quam foliis multo brevioribus; floribus flavidis 4 
cm longis, calycis cylindraceis, obliquis, 1.8 cm longis, breviter 
3-lobatis; corollae tubo extus glabro, deorsum (1.5 cm) angus- 
tato et intus villoso, sursum expanso, lobis late reniformi-ovatis, 
10 mm latis; folliculis usque ad 40 cm longis, circiter 5 mm 
diametro, seminibus 12 mm longis. 
Hoihow, McClure 7648, October 12, 1921, in dry sandy 
waste places at low altitudes, with the local name hung fa. The 
species is also represented by Hongkong herbarium No. 453 
collected in Hainan October 22, 1893, without locality. 
A species radically different from the few representatives of 
the genus known from China, strongly characterized by its 
short, 5-foliolate, simply pinnate leaves; its greatly abbreviated, 
few-flowered inflorescences; and its cylindric, oblique calyx tube.
