Dr. H. 0. FORBES'S NEW GUINEA EUBIACEyE.— II. 

 By H. F. Werxiiam, D.Sc, F.L.S. 



(Concluded from p. 77.) 



The following paper, wliieh includes the three genera Gouldia, 

 Timoniiis, and Psychotria, concludes our account uf Dr. Forbes's 

 New Guinea Kubiacese : — 



<y 



Gouldia. All the previously-known species of this genus are 

 confined to the Sandwich Islands ; the following, from the Sogere 

 region, is therefore of especial interest. Our specimen unfortunately 

 bears fruit only, and no flowers; but the habit and the fruit- 

 structure leave no doubt that it should be assigned to this genus. 



Gouldia papiiar.a, sp. nov. 



Ai'bor (?) ramulis validiusculis novissimis tamen gracilioribus 

 valde complanatis minute necnon dense ferrugineo-pulverulentibus, 

 mox cortiee lignoso crasso aspero indutls cinereo. Fulia finne char- 

 tacea lanceolata nonnunquam elliptica utrinque acuminata apice 

 obtusa, supra glabra in siccitate dilute viridia venis impressis, subtus 

 minute pra'sertim in venis fulvo-pubescentia ; vencs primariaj utrinque 

 manifestae, subtus prominula', laterales utrinque 9-12 ; petiohis brevis 

 supra canaliculatus glaber, dorso rotunde-convexus fulvo-pulveru- 

 lens ; stipulce crassiusculse lanceolate acuminata dorso prsesertim 

 basin versus rufo-pubescentes dorsoque tandem carinatte mox caducae. 

 Panicula axillaris pedunculo rectissimo longo in rachidem minute 

 ferrugineo-puberulam producto, brachiis latei-alibus verticillatis rio-ide 

 necnon recte perpendicularibus, bracteaj postanthesin caducae. Baccce

 tibus affixae sessiles, apice umbonatae, calyce omnino absente, bilocu- 

 lares, seminibus parvis numerosis.

The distinctive features of the species are the long-stalked axillary 

 panicles, the large berries, and the 2>ubescence of the leaves. Leaves 

 10-14 cm. X 3-5 cm. ; petiole rarely so much as 9 mm. long; stipules 

 10 mm. X 3 mm. Peduncle 3^ cm. or longer j panicle (fruiting), 

 to 6 cm. or longer, and 6 cm. wide at base. Perry 5 mm. in 

 diameter. 



TiMONius. (See Valeton, in Bull. Dep. Agric. Ind. Neder. xxvi. 

 (1909).) Every collection of New Guinea plants reveals species 

 hitherto unknown of this interesting genus. Those gathered recently 

 in Dutch New Guinea, on Mt. Carstenz, which I described in Trans. 

 Linn. Soc. ix. (191G) 73-74, are very quaint in habit, altogether 

 unlike any described before — a phenomenon due largely, without 

 doubt, to the considerable elevations at which they occur. The 

 following, though quite distinct, are more normal in their apj^ear- 

 ance, and comparable with previously known forms. The genus is 

 abundantly representedin the Indo-Malayan region, where it rej^laces, 

 to a considerable degree, Guettarda of the New \V^)rld.
