bluish-green, when dry oblong-cylindric, apiculate, about 4 cm 
long. 1.5 to 2 cm in diameter, somewhat exserted from the calyx, 
the calyx-lobes ovate, acute, about 1.5 cm long.

February 15, 1913. 
A species somewhat resembling and manifestly closely allied to Fagraea 
longifiora Merr., from Mount Banajao, Luzon. It differs, however, in its 
somewhat exserted fruits and in its vegetative characters, the leaves of the 
two being entirely different in shape. 
APOCYNACEAE 
ALYXIA Banks 
ALYXIA REVOLUTA sp. nov. 
Frutex scandens, glaber, ramis crassis, quadrangulatis ; foliis 
quaternatis, anguste oblongis, crassissime coriaceis, usque ad 18 
cm longis, obtusis, basi acutis et plus minusve decurrentibus, 
margine valde revolutis, supra olivaceis, nitidis, subtus glaucis; 
nervis lateralibus numerosis, supra obscureis, subtus obsoletis; 
petiolo 3 ad 4 cm longo ; infructescentiis axillaribus,' solitariis, 
ramosis, 3 ad 4 cm longis; fructibus ellipsoideis, circiter 1.4 cm 
longis, apiculatis, vel dispermis et in medio constrictis. 
A scandent glabrous shrub, the branches stout, distinctly 4- 
angled, up to 1 cm in diameter, the ultimate parts 4 to 5 mm 
in diameter, the internodes 4 to 8 cm long. Leaves 4-nate, very 
thickly coriaceous, narrowly oblong, 13 to 18 cm long, 3.5 to 5 
cm wide, obtuse, base acute and usually somewhat decurrent, the 
margins very prominently revolute, the midrib very prominent, 
the upper surface olivaceous, shining, the lower glaucous ; lateral 
nerves numerous, slender, obscure on the upper surface, obsolete 
on the lower ; petioles very stout, 3 to 4 cm long. Cymes axillary, 
solitary, their peduncles 1 cm long or less, the branches usually 
3, short, the bracteoles persistent. Fruits ellipsoid, when fully 
mature black or dark-purple, the immature ones yellowish-brown 
when dry, about 1.4 cm long, somewhat wrinkled, stipitate, apic- 
ulate, 1-seeded, or sometimes constricted in the middle and 2- 
seeded.

Luzon, Tayabas Province, Mount Cadig, Bur. Sci. 25515 Yates, December 
12, 1914, in the mossy forest, altitude at least 800 meters. 
A most characteristic species, readily distinguished by its narrowly 
oblong, very thickly coriaceous, stiff leaves which are glaucous beneath, 
the nerves here obsolete, but especially by the very strongly revolute mar- 
gins. Its alliance is with Alyxia sibuyanensis Elm.
