2 lines long, with 2 minute bracteoles under the ovary. Calyx-teeth small. 
Corolla about 5 lines long, slightly pubescent outside with appressed hairs, the 
petals remaining long coherent in a narrow tube. Fruit ovoid, fin. long, black 
and fluted, crowned by the small persistent cup-shaped calyx-limb. 
Hab.: Scrubs North Coast Railway. Fruit ripe in March, 
2. P. rigidiuscula (leaves somewhat rigid), F. v. M. et Bail. Bot. Bull. i. 
A straggling shrub, the leaves so far as known (only two small specimens 
obtained) 2 to 3in. long, broad-lanceolate to ovate, the margins minutely and 
distantly denticulated with callous often pointed teeth or almost entire, usually 
acuminate, soon glabrous, rather conspicuously reticular-venulated, shining above, 
paler green beneath. Racemes spike-like, shorter than the leaves. (Flowers not 
seen.) Fruits ovate-ellipsoid, about 4 lines long, slightly hairy and nearly sessile. 
Seed turgid-ovate, its testule smooth, membranous, brownish-grey ; fresh albumen 
carnulent, embryo inconspicuous. 
Hab.: Summit of Mt. Bartle Frere, Bellenden Ker Expedition , August, 1889. 
3. P. reducta (referring to venulation), F. v. M. Viet. Nat., June 1892. A 
small tree of about 25ft. in height, with appressed hairs on the branchlets and 
petioles. Leaves mostly lanceolate, entire, gradually acuminate, from If to 2fin. 
long, almost suddenly passing into the slender petiole, nearly glabrous above, 
slightly puberulous beneath, the venulation much concealed. Racemes terminal 
and oftener axillary ; pedicels very slender. Bracts and bracteoles minute at the 
upper end of the pedicel. Calyx-teeth very short. Fruit ovate-globular, slightly 
oblique, without longitudinal lines, its summit emerging from the calyx and some- 
what pyramidal, about 2f lines long, on pedicels of about the same length ; endo- 
carp thinly cartilaginous, the spurious dissepiment longitudinally divisible into 
halves. Seeds 1 or 2, if 2 only one side turgid. Albumen oily, somewhat 
granular. Embryo minute, roundish. 
Hab.: Russell River, W. Sayer (F. v. M. l.c.) 
4. P. alangiacea (Alangium-like), F. v. M. Fragm. viii. 8. A tree 
about 30ft. high. Leaves lanceolate, entire, almost glabrous, 3 to 5in. long, 1 to 
lfin. broad, at first slightly tomentose, of a paler green on the under side and 
scarcely glossy, thin coriaceous, the lateral nerves erecto-patent, margins ciliolate. 
Racemes terminal, solitary, 3 to 5in. long, shortly pedunculate. Flowers 
numerous, 4 or 5-merous. Pedicels solitary. Bracteoles linear or ovate-lanceolate, 
about 1 line long. Corolla 4 to 5 lines long, thinly pilose. Filaments scarcely 
exceeding 2 lines. Anthers twice as long, narrow oblong-linear, obtuse. Style 
3 lines long, filiform, very thinly coriaceous. Stigma depressed, very shortly 
2-lobed. — F. v. M. l.c.

G. ANOPTERUS, Labill. 
(From ano, upwards, and pteron, a wing ; wing of seed.) 
Calyx-tube very short, adnate to the broad base of the ovary ; lobes 6 to 9, 
short, persistent. Petals as many as calyx-lobes, imbricate, spreading, deciduous. 
Stamens as many as petals ; anthers versatile. Ovary free, except the broad 
base, 1-celled, with several ovules attached to 2 parietal placentas ; style 2-lobed, 
the lobes stigmatic along the inner side. Capsule oblong-conical, thickly 
coriaceous, opening in 2 recurved valves with the placentas on their margins. 
Seeds pendulous, imbricate, flattened ; testa membranous, dilated at the hilum 
end into a broad membranous wing, the nucleus at the opposite end small,
