NAUCLEA. RUBIACE E. 391 
lobes 5, patent, oval-oblong. Anthers either included or protruded, shorter 
than the lobes of the corolla. Style filiform, protruded. Stigma oblong or 
ovate, tumid, undivided. Capsules 2-celled, sessile upon a receptacle, not 
tapering gradually at the base. Seeds several, imbricated, winged or with a 
gland at the hilum, attached to an oblong placenta that is adnate to the dis- 
sepiment. Embryo inverted in a fleshy albumen.—U narmed trees or more 
rarely shrubs. Leaves opposite, or 3-4 verticillate, petioled or sessile. Sti- 
pules interpetiolar, deciduous. Partial peduncles terminal at the end of the 
branches, or at the extremity of 2-leaved terminal or axillary general pedun- 
cles, bearing each one globose head of sessile flowers. Bracteas or floral 
leaves at the end of the general peduncle, none at the base of the head. Pa- 
lez or bracteoles among the flowers, linear. 
In this genus much confusion has been created by botanists not distinguishing be- 
tween the partial peduncle and the general one which bears it : the line of demarca- 
tion is however well marked, by either a P aua of smallleaves or bracteas, or when 
they fall off by the presence of a joint. From this reason the old figures cannot be 
referred to satisfactorily, nor even the specific characters hitherto given in systema- 
tic works. The length of the general peduncle is often of little consequence, while 
that of the partial one may assist in distinguishing species.

of the nerves on the under side of the leaves: branches brachiate : stipules 
oval: leaves petioled, ovate or oval or obovate-obtuse or with a short blunt- 
ish point: general peduncles opposite, terminal, resembling and often pass- 
ing into floriferous shoots, bearing a pair of small deciduous leaves ; par- 
tial ones scarcely so long as the globose head of flowers, the terminal one on 
the branch usually without a general one: limb of the calyx very short and 
almost truncated : lobes of the corolla spreading : anthers shortly protruded : 
style long ; stigma narrow-oblong, calyptriform : capsules containing 2 cocci 
splitting at the inner angle.—Roab. Cor. 1. t. 52; fl. Ind.1. p. 513; (ed Wall.)

Notwithstanding that Linnseus refers to Rheede’s figure, we suspect the 
present to be his Cephalanthus or Nauclea orientalis: Lamarck’s plant of the 
same name is from the Moluccas, but it also may, judging by the figure gi 
ven in the illustrations, prove not to be distinct. Cephal. pilulifer is th 
re with the flowers fallen off, leaving the head of ovaries about the size 
ora pea. :
