198 FLORULA HONGKONGENSIS. 
24. Canthium undulatum, Champ., sp. n.; fruticosum, inerme, foliis 
vee’ longiuscule petiolatis ovali-oblongis acuminatis margine undulatis 
' eoriaceis glabris supra nitidissimis subtus ad axillas venarum glan- 
dulosis, cymis axillaribus breviter pedunculatis petiolum paulo su- 
perantibus, floribus pentameris. 
Happy Valley woods; rare. Very near to the East Indian C. didy- 
mum, and still more so to Arnott’s C. lanceolatum from Ceylon, and 
perhaps with some others should be considered as a mere variety of 
Gærtner’s species. The petioles are, however, much longer (about 
half an inch); the leaves narrower, more acuminate, and usually un- 
dulate on the margins, and the stipules much shorter. The fruit in a 
. young state is ovoid, without the lateral furrows, which however, m 
most Canthia, are only to be seen in an advanced stage. 
25. Ixora stricta, var. incarnata, Roxb. Fl. Ind. vol. i. p. 379, ejusd. 
ed. Wall. p. 389. 
Woods near the Buddhist Temple, East Point. Flowers pale pink. - 
Not distinguishable in the dried state from the white-flowered J. blanda, 
or J. alba, Roxb. (non Linn.), which, as suggested by Roxburgh, ap- 
pears to be a mere variety of I. stricta. 
26. Pavetta Indica, Linn.—DC. Prod. vol. iv. p. 490. 
Happy Valley and West Point. 
27. Psychotria elliptica, Ker.— DO. Prod. vol. iv. p. 490.—P. 
Reevesii, Wall. DC. 1. c. p. 519.— Grumilia Reevesii, Hook. et Arn. Bot. 
_ Beech. p. 193. : 
Very common in Hong-Kong. Berries red when ripe. Certainly 
a congener with the numerous species of the section Mapouria of 
Psychotria, and very nearly allied to the common South American P. 
alla. Tt is indeed very doubtful whether any portion of Grumilia can 
. be maintained as a genus distinct from Psychotria. 
28. Psychotria serpens, Linn.—DC. Prod. vol. iv. p. 519.—P. scan- 
dens, Hook. et Arn. Bot, Beech. p. 193. 
Common in Hong-Kong. Berries white, There appear to be two 
varieties, one with the inflorescence less divided and the berries more 
. succulent than the other, but possibly gathered in different states, and 
. I cannot, from the specimens before me, either from Hong-Kong or 
from the main land, detect any specific differences. - 
29. Pæderia fetida, Linn.—DC. Prod. vol. iv. p. 471. 
Mount Vietoria. Corolla 6 lines long, white, with a slight tinge of
