The alliance of this species is undoubtedly with Ixora sparsi- 
flora Elm., from which it is at once distinguished by its much 
narrower, entirely differently shaped leaves which are acute, not 
broad and cordate at the base. From Jxora longistipula Merr. 
it is at once distinguished by its entirely different inflorescences.

MORINDA CORIACEA sp. nov. 
Frutex scandens, glaber, ramulis circiter 2 mm diametro, 
foliis crasse coriaceis, oblongis, 7 ad 11 cm longis, utrinque subae- 
qualiter angustatis, basi acutis, apice obtuse acuminatis, nervis 
utrinque circiter 8, tenuibus, distinctis; fructibus solitariis vel 
paucis, globosis, circiter 12 mm diametro. 
A woody, glabrous vine, the branches dark-colored when dry, 
the ultimate branchlets subterete, 2 mm in diameter or less. 
Leaves rather thickly coriaceous, oblong, 7 to 11 cm long, 1.8 
to 3.5 em wide, usually olivaceous and slightly shining when 
dry, subequally narrowed to the acute base and to the usually 
blunt-acuminate apex; lateral nerves about 8 on each side of 
the midrib, slender, rather distinct as are the primary reticula- 
tions; petioles 5 to 7 mm long; stipules somewhat sheathing, de- 
ciduous, about 4mm long. Fruits terminal, solitary, in pairs or 
sometimes threes, umbellately arranged, globose, rather many- 
seeded, about 12 mm in diameter, yellow when fresh, black or 
brown when dry, their pedicels usually about 1 cm in length.

casio, April 25, 1919, along small streams at low altitudes. 
A species belonging in the group with Morinda umbellata Linn., 
but distinguished from all forms of this species known to me by 
its vegetative characters.
