cent to glabrous, obtuse, 8 to 11 mm long. Flowers pedicelled,

indicated. 
A strongly marked species among those with pubescent vegetative parts, 
not very similar to any described form, but most closely allied to Medinilla 
cordata Merr. It is distinguised from Medinilla cordata by numerous char- 
acters, especially in its entirely differently shaped, prominently petioled 
leaves which are gradually narrowed to the acute base. 
MEDiNiLLA LONGIDENS sp. nov. 
Frutex circiter 1 m altus, perspicue plumoso-tomentosus ; 
ramis ramulisque teretibus; foliis oppositis, valde inaequalibus, 
chartaceis, ovato-ellipticis ad oblongo-ovatis, minoribus usque 
ad 4 cm longis, majoribus usque ad 8 cm longis, acute acuminatis, 
basi angustatis, obtusis ad leviter cordatis, 5-plinerviis, petio- 
latis; inflorescentiis axillaribus, breviter pedunculatis, plerum- 
que bifloris; bracteis conspicuis, lanceolatis, acuminatis, circiter 
15 mm longis, utrinque pubescentibus ; floribus 4-meris, brevis- 
sime pedicellatis, calycis lobis lanceolatis, acuminatis, 4 ad 5 
mm longis. 
An erect shrub about 1 m high, the branchlets, petioles, lower 
surface of the leaves, and inflorescences densely plumose- 
tomentose, the indumentum dirty brown or pale, the branches 
and branchlets terete, the former glabrous, pale, the latter about 
2 mm in diameter. Leaves opposite, petioled, those of each pair 
very unequal in size, the larger ones 6 to 8 cm long and 2.5 to 
3.5 cm wide, the smaller ones 3 to 4 cm long and 1.5 to 2 cm 
wide, chartaceous, pale-grayish when dry, acuminate or acute, 
base narrowed, obtuse to slightly cordate, 5-plinerved, the trans- 
verse nerves and reticulations obsolete, the upper surface gla- 
brous ; petioles of the larger leaves 8 to 12 mm long, of the smaller 
ones 2 to 4 mm in length. Inflorescences axillary, solitary, 
mostly 2-flowered, the peduncles 5 mm long or less, the flowers 
subtended by an involucre of pink, lanceolate, acuminate, pubes- 
cent bracts about 15 mm in length. Flowers 4-merous. Young 
fruit ovoid, 4-celled, pubescent, about 6 mm long, the persistent 
calyx-teeth lanceolate, pubescent, acuminate, 4 to 5 mm long.
