Goniothalamus trunciflorus sjj. nov. 



A tree with oblong, short acuminate, glabrous leaves, and large flowers, 

 solitary (or fascicled?) on the trunk, the outer petals ovate-lanceolate, 

 6.5 to 9 cm. long. Branches dark brown, the ultimate branchlets light 

 colored, glabrous. Leaves subcoriaceous, shining on both surfaces, the apex 

 short acuminate, the base acute, the margins recurved, 18 to 2.5 cm. long, 

 7 to 8 cm. wide; nerves distant, distinct beneath, 8 to 10 on each side of 

 the midrib, very laxly anastomosing, the reticulations lax; petioles 1 to 

 1.5 cm. long, glabrous. Flowers red, the peduncles 3 cm. long, glabrous. 

 Sepals subreniform to broadly ovate, acute, 1 em. wide, slightly pubescent. 

 Outer petals membranous, 9 cm. long or less, 2 to 3 cm. wide, tapering 

 above to the long slender acuminate apex, both surfaces sparingly pubes- 

 cent with short hairs; inner petals coriaceous, broadly ovate, acuminate, 

 2 cm. long and 1.5 cm. wide or smaller, arched, the margins cohering, the 

 claw very short, broad, dertsely cinereous pubescent outside and also on 

 the upper portion within. Stamens many, 2.5 mm. long, the anther cells 

 obscured by the overlapping, rounded-truncate connectives. Ovaries many, 

 pubescent, 2.5 mm. long, 1-ovuled; styles elongated 2-cleft at the apex. 

 Fruit unknown. 



Type specimen : Tinuan River, Province of Tayabas ( Infanta ) , Luzon 

 (774 Whitford), September 6, 1904. A tree growling in the hill forests 

 at an altitude of about 120 m. above the sea, at once distinguished by its 

 cauline inflorescence, the large flowers being borne near the base of the 

 trunk. The only other described Philippine species that approaches this 

 is JJvaria amuyon Blanco = Unona cauliftora Blanco. The latter species 

 was referred by F.-Villar to Melodornni fulgens Hook. f. et Th.. to which 

 Blanco's description does not all apply. Blanco's species is apparently 

 represented by No. 775 Whitford, from the same locality as the above, 

 but as the specimens are in fruit it is quite impossible to definitely determine 

 just what Unona caiiUflora Blanco may be. However, Blanco's descrip- 

 tion does not at all apply to the species here proposed. 



Mitrephora reflexa, sp. nov. 



A medium-sized tree with elliptical-ovate, nearly glabrous leaves 17 cm. 

 long or less, and rather large leaf -opposed hermaphrodite flowers, the outer 

 petals reflexed in anthesis, the inner very diff"erent from the outer, con- 

 nivent, vaulted. Branches dark brown, glabrous, the ultimate branchlets 

 slender, light gray, more or less ferruginous pubescent, the terminal buds 

 densely so. Leaves 8 to 17 cm. long, 5 to 8 cm. wide, the apex acuminate, 

 the base acute to some^yhat rounded, glabrous and shining above, slightly 

 ferruginous pubescent on the nerves and midrib beneath ; nerves prominent 

 beneath, about 12 pairs; petioles thickened, rugose, slightly pubescent, 1 

 cm. long. Flowers yellow, about 5 cm. in diameter when spread, on a short 

 leaf-opposed axis, only one flower developing at a time, the peduncle stout, 

 densely ferruginous-pubescent, about 6 mm. long. Sepals orbicular-ovate, 

 about 6 mm. long, densely ferruginous pubescent. Outer petals broadly 

 ovate, 2.5 cm. long, 1 cm. wide, subcoriaceous, acute, glabrous withrn, 

 densely cinereous-ferrugineous pubescent outside. Inner petals 1.5 cm.
