NAUCLEA MINDANAENSIS sp. nov. 
Arbor parva, 5 ad 10 m alta, inflorescentiis exceptis glabra 
vel subtus foliis parce pubescentibus ; foliis oblongo-obovatis ad 
oblongo-oblanceolatis, usque ad 20 cm longis, acuminatis, infra 
angustatis, basi abrupte rotundato-cordatis, nervis utrinque 
circiter 11, prominentibus ; pedunculis solitariis, 3 ad 5 cm 
longis, capitulis (in anthesi) 4 ad 5 cm diametro. 
A small tree, glabrous or nearly so. Branches grayish, terete, 
wrinkled when dry, glabrous. Leaves oblong-obovate to oblong- 
oblanceolate, rarely obovate, coriaceous, 12 to 20 cm long, 3,5 
to 9 cm wide, shining when dry, the lower surface a little paler 
than the upper one and sometimes slightly pubescent on the 
midrib and nerves, the apex distinctly acuminate, narrowed 
from about the middle to the abruptly' rounded or rounded- 
cordate base, the base 1 to 2 cm wide; lateral nerves about 11 on 
each side of the midrib, prominent, obscurely anastomosing, the 
reticulations slender, rather distinct, somewhat lax; petioles 5 
to 10 mm long; stipules oblong, obtuse, 2 to 2.5 cm long. Pe- 
duncles solitary, terminal, 3 to 5 cm long. Heads globose, in 
anthesis 4 to 5 cm in diameter, the bracts, if present, very early 
deciduous and at the apices of the peduncles. Calyces free, 3 
mm long, angled, the tube truncate, pubescent at the apex, the 
bracteoles none. Corolla about 1.5 cm long, the tube slender, 
gradually widened upward, glabrous, 5-lobed, the lobes oblong- 
ovate, obtuse, 1.5 mm long, somewhat pubescent externally. 
Styles exserted about 8 mm, the stigmas obovoid.

A species manifestly allied to Nauclea keniii Merr., and possibly the 
flowering stage of that species, although this is unlikely. It differs from 
that species in its much smaller leaves, and somewhat fewer nerves. 
NAUCLEA MONOCEPHALA sp, nov. 
Arbor parva capitulis exceptis glabra; foliis oblongo-ellipticis 
ad oblongo-ovatis, usque ad 25 cm longis, coriaceis, brevissime 
obtuseque acuminatis vel obtusis, basi rotundatis vel subacutis, 
nervis utrinque 8 ad 10; pedunculis solitariis, 5 cm longis, ad 
apicem bracteatis ; capitulis in anthesi 6 cm diametro, calycis lobivS 
pubescentibus, 7 mm longis, deciduis, floribus ebracteolatis. 
A small tree, about 6 m in height, glabrous except the heads. 
Branches reddish-brown, terete, wrinkled when dry. Leaves

to 12 cm wide, or the uppermost pair only about 12 cm long,
