204 . MERRILL. 
lanceolate, thickened, acuminate, 3 mm long lobes or teeth, these teeth 
narrow and keeled on the inside. Petals 5, glabrous, in bud strongly 
rostrate, imbricate, elliptic-ovate to elliptic-oblong, slightly inequilateral, 
acuminate, about 9 mm long, 5 to 6 mm wide. Stamens about 65, 
1-seriate, subequal, the filaments slender, more or less coherent below 
in five phalanges, some or all ultimately free or nearly so, 7 to 8 mm 
long, glabrous; anthers narrowly linear-oblong, terete, straight or nearly 
so, erect, in bud inflexed, gradually narrowed to the base, about 5 mm 
long, 0.5 mm in diameter, the connective not produced, appendages none, 
opening by two terminal slits, each cell prolonged into a 0.5 mm long, 
compressed tube, slightly obliquely truncate. Ovary adherent, to the 
calyx, 5-celled, the ovules indefinite, on all sides of the thickened 
placenta which is attached in the lower inner angle; style elongated, 
rather stout, about 12 mm long; stigma 0.5 mm in diameter, punctiform. 
Fruit unknown. 
Luzon, Province of Camarines, near Daet, For. Bur. 14349 bis Aguilar, July, 
1909, in forests near the Maniba River (type): Province of Laguna, Dajican, 
Bur. Sci. 8983 Foxworthy, July, 1909, altitude about 300 m. 
Aguilar states that the flowers are red, and his specimens bear open flowers; 
Foxworthy states that they are greenish-white, but on his specimen the flowers 
are not quite mature. The diameter of the trunk is given by Aguilar as 27 em, 
‘and by Foxworthy as 25 em. 
This new genus belongs in the Astronieae, and is perhaps most closely allied 
to the Bornean monotypic genus Plethiandra, It is, however, very different from 
that genus and from all others in the tribe and family. Characteristic features are 
its prominently 5-lobed star-shaped calyx, and especially its very numerous 
stamens, the anthers being slender and gradually narrowed to the base, opening 
by two terminal slits, the cells being produced into very short, compressed tubes, 
the connectives not produced and in no way appendiculate. 
In the entire family the only genera previously known in which numerous 
stamens are found are the Bornean Plethiandra, mentioned above, and the Amer- 
ican ones Calyptrella and Miconia. 
CEPHALOMEDINILLA gen. nov. 
Flores 4-meri. Calycis tubus ovoideus, limbus valde 4-lobatus. Petala 
anguste oblongo-obovata, leviter inaequiliteralia, rotundata vel subacuta. 
Stamina petalorum numero dupla, aequalia; antherae lineari-lanceolatae, 
elongatae, apice 1-porosae, connectivo basi non producto, antice bilobo, 
postice minute 1-calcarato. Ovarium calycis tubo adhaerens, 4-loculare, 
vertice dense pilosum. Ovula in loculis numerosa, placentis prominulis 
angulo interiore loculi affixis; stylus elongatus, stigmate punctiformi. 
Bacca ignota. Frutex scandens, ramulis foliis junioribus inflorescentiis- 
que plus minus dense simpliciter pilosis. Folia opposita, sessilia, valde 
inaequalia, integerrima, penninervia. Flores in capitulis axillaribus, 
sessilibus, multifloris dispositi, rosei; alabastro in bractea clausa incluso.
