590 XXXIX. OLACINEJE. (Maxwell T. Masters.) [PMeboeah/mm. 



fleshy, hypogynous, 5-lobed, lobes opposite the petals. Ovan conic, 

 1 -celled; style subulate ; ovules 2, pendulous. Fruit oblong with. » crus- 

 taceous rind. Seed pendulous ; albumen coriaceous, lobulate, ruminate ; 

 embryo minute.— Disteib. Species 2 or 3, natives of the Malay peninsula 

 and islands. 



1. P. Grlffithiana, Mast., leaves obovate-oblong shortly and abruptly 

 acuminate, stamens adherent to the base of the corolla. Platea Griffithiana, 

 Miers Contrib. i. 97. 



Tenasserim ; at Mergui, Griffith. „ • , 



A glabrous shrub. Branches terete, slender, slightly compressed, rugose, yeUowisb. 

 Leaves 6-8 by 3 in., coriaceous, glabrous, pale, concolorous, midrib prominent beneath, 

 margins revolute ; petiole ^-4 in., sulcate. Oymes axillary, erect, spicate, scarcely 

 longer than the petiole, few-flowered ; pedicels puberulous. Oalyx-lobes imbricate, 

 ovate, ciliolate. Corolla much longer than the calyx, funnel-shaped, limb 5-iobed, lobes 

 ultimately inflexed at the point. Filaments linear, glabrous. Ovary very short, sur- 

 rounded by a pentagonal disk, 1-celled ; style conic, pilosulous, stigma obscurely 3 lobed. 

 Fruit 14 by i in., oblong, obtuse ; stone thick, bony, 1 celled by abortion. Seed solitary, 

 pendulous from the apex of the cell, integument densely permeated by spiral vessels, 

 albumen fleshy lobulate. — Kurz refers Miqjiel's Gonocaryw/n f gracile to this species, 

 but Miquel's plant is described as having a longer inflorescence, two styles and a diffe- 

 rent fruit. 



2. P. Xiobbiana, Mast. ; leaves oblong acuminate, stamens adherent to 

 the corolla for the greater part of their length. Platea Lobbiana, Miers 

 Contrib. i. 97 ; Wall. Cat. 9052.

A shrub or tree ? Branches a,ngular. Leaves 4J-5J by 1S-2J in., coriaceous, glabrous, 

 margins revolute, nerves prominent beneath ; petiole \ in., sulcate, rugose. Cymes 

 axillary, peduncled ; peduncle erect, shorter than the petiole. Flowers subfascicled, 

 ^ in. Calyx i\- in., cup-shaped, lobes imbricate. CoroUa ^ in., funnel-shaped, limb 

 5-lobed ; lobes oblong, recurved. Filaments glabrous ; anthers ovoid, compressed, con- 

 nective wide at the base. Disk hypogynous, 5-lobed. Ovary hirsute, ovoid, tapeiing 

 into a short style. Fruit If in., oblong, obtuse, olive-coloured, obscurely 2-celled. 



A plant collected by Wallich in Tavoy (Gat. 9051), has the habit, inflorescence, and 

 floral characters (ovary not seen) of Phlebocalymna, but the fruit is different, and more 

 like that described by Miquel under his Gonocaryvm ? gracile (Fl. Ind-Bat. Suppl. i. 

 343). Indeed, 1 should refer both Wallich's 9051, and Heifer's 817, Kew. dist. from Te- 

 nasserim ? which evidently belong to the same species, to Miquel's genus, but for the dif- 

 fei'ent habitat (Miquel's plant is Sumatran), and that I have not seen either the ovaries 

 of Wallich's or Heifer's plant in any specimen of Miquel's. Kurz, in Journ. As. Soo. 

 Eeng. xxxix. pt. 2, p. 72, refers Gonocarytimf gracile to Phlebocalymna Griffithii, 

 from which it differs in the longer inflorescence, and especially in the fruit. — Tlie fol- 

 lowing description applies to VVallich's plant, to which 1 would give the provisional 

 name Gonocaryum i WaUichii; A glabrous shrub. Branches terete, bark yellow. 

 Leaves 6 by B in., glabrous, coriaceous, oblong, tapering to both ends, shortly acumi- 

 nate, entire ; nerves depressed on the upper, prominent on the lower surface ; petiole 

 scarcely 4 in., rugose, channelled. Eacemes axillary, solitary or geminate, half the 

 length of the leaves ; rachis angular; pedicels J in., horizontal, ciliated, 1-2 flowered. 

 Flowers unisexual or polygamous ? Calyx pateriform, deeply divided into 5 imbricate, 

 ovate acute, ciliated lobes. CoroZ/a twice the length of the calyx, cylindric, obtuse; 

 petals erect, thick green, oblong with inflexed points, valvate and cohering by the mar- 

 gins but readily separable. Stamens 5, alternate with the petals and agglutinated to 

 their edges, but easily separable, filaments glabrous, anthers 2-celled, introrse. Ovary 

 abortive ; style 1, fihform, covered with short erect white appressed hairs. Fruit 2 by 

 1 in., obliquely oblong, tapering to both ends, 1-oelled ; rind fibrous, corky. Seed not
