368 Flora of the Malayan Peninsula. 
slender, angular when dry, glabrous. Leaves coriaceous, alternate, . 
opposite or in verticils of 3 together; elliptic-oblong or elliptic-lanceo- 
late, obtusely acute at apex, attenuate at base; both surfaces glab- 
rous, greyish-green when dry, 5—8 cm. long, 2—3 cm- broad; midrib 
slender, raised on both surfaces; main nerves invisible in fresh, 
rather prominent in dry, specimens, 3—5 pairs, irregular, very 
oblique, curving to anastomose near the margin in an areolate 
reticulation; petiole 1 cm. long, rather stout. Flowers in slender 
racemes from the axils of the leaves or of fallen leaves, reaching 1—5 
cm. in length and about 6-flowered; rhachis, pedicels and bracts 
minutely puberulous; pedicels 3—4 mm. long; outer bract small, 
ovate, acute, embracing a pair of flowers each of which is supported 
by a shallow cup-shaped bracteole. Calyxz-tube cylindric, 3—4 mm. 
long; the limb short, truncate, waved at the margin. Corolla 
tubular, glabrous, bright red, curved, inflated upwards and con- 
stricted at the neck in bud, 4—5 cm. long; lobes 6, linear, sub- 
spathulate, 8—10 mm. long, eventually reflexed. Stamens 6; 
anthers oblong, 2 mm. long, filaments about 4 mm. long, slender. 
Ovary cylindric, surmounted by a thickened cushion from which 
springs the filiform style, as long as the stamens; stigma globose. 
Fruit not seen. Arculus Duthieanus, van Tiegh. in Bull. Soc. Bot. 
Fr. XLII. 445.

van Tieghem makes this a separate genus nearer to Hlyiranthe than to 
Loranthus. I do not find the two bracteoles to each flower that he discovered, 
but there certainly is one. I prefer to retain Arculus in Loranthus, but it 
certainly is different from the rest of the genus. 
2. LOXANTHERA, Blume. 
Parasitic shrubs. Leaves coriaceous, entire, exstipulate, opposite 
or alternate. Flowers in short cymes from the axils of the leaves or 
of fallen leaves; bract ovate, very small, embracing the base of the 
calyx-tube. Calyx-tube cylindric; limb cupular, irregularly cleft. 
Corolla-tube very long, contracted a little above the base and again 
above the insertion of the filaments; lobes 6, linear-spathulate, 
reflexed in flower. Stamens 6; filaments slender, arched at the top 
and broadening into the back of the connective rather below its 
middle; anthers linear, cells 2, parallel. Ovary cylindric; style fili- 
form; stigma clavate. Fruit of Loranthus, etc.—Distris. Two 
species, in the Malay Peninsula and Archipelago.
