770 LXIV. EUBIAOE^. [Psychotria. 



Stipules interpetiolar, 1 on each side, membranous, and often connate within the 

 petioles, and very deciduous in the Australian species, smaU, persistent, and 1 or 

 2 on each side, in many American ones. Flowers usually small, in terminal 

 cymes, or, in species not Australian, axillary. 



A large genus, ranging over the tropical regions both of the New and the Old World. The 

 Australian species appear to be all endemic. The limits of the genus are not well defined. 

 The above character includes Grumilia, usually but vaguely distinguished by the seed, and 

 excludes Chasalia, Palicourea, and others scarcely differing but by the length of the corolla-tube, 

 characters requiring confirmation by the study of very numerous little known or undescribed 

 species.— Smtft. 



Section I. Grumilia/. — Calyx limb (at least in the Australian species) obscurely sinuate- 

 toothed. Pyrenes not furrowed. Seeds ruminate. 



Leaves obtuse. Cymes divaricate. Corolla 2 to 3 lines long 1. P. nesophila. 



Leaves acuminate. Cymes paniculate. Corolla 1 line long 2. P. Dallachiana. 



Section II. ItKapoiirea. — Oalyx-limb (at least in the Australian species) distinctly toothed 

 Pyrenes and seeds longitudinally furrowed. Stipules membranous, 1 on each side, deciduous. 



Flowers capitate on the branches of the cyme. Leaves usually softly 



pubescent or tomentose 3. P. loniceroides. 



Flowers in corymbs, cymose to the last. Leaves usually glabrous. 



Corolla about 2 lines long ; lobes as long as the cylindrical tube. 



Corolla glabrous outside. Fruit ovoid 4k. P. daphnoides. 



Corolla hoary-tomentose. Fruit globular 5. P. poliostemma. 



Corolla about 3 lines long ; lobes shorter than the ovoid tube. Leaves 

 thick and coriaceous 6. P. Fitzalani. 



Corolla 2 lines long, bearded inside at the base. Leaves almost mem- 

 branous 7. P. nematopoda. 



Corolla pubescent outside; the tube rather longer than the lobes. 

 Leaves 1 to 2in. long 8. P. Simmondsiana. 



1. P. nesophila (an island species), F. v. M. Fragm. ii. 135 ; Benth. Fl. 

 Anstr. iii. 427. A shrub or tree, quite glabrous. Leaves broadly ovate obovate 

 or almost oblong, obtuse or very shortly and obtusely acuminate, 1 to Sin. long, 

 narrowed into a rather long petiole, thinly coriaceous. Flowers in shortly 

 pedunculate very divaricate terminal cymes. Calyx-limb truncate or obscurely 

 toothed. Corolla glabrous outside, very hairy inside ; tube IJ lines long ; lobes 

 as long as the tube, thickened and hood-shaped at the tips. Ovules broad. 

 Fruit globular, smooth, the pyrenes very obscurely ribbed. Seeds hemispherical, 

 very much ruminate-rugose. 



Hab.: Albany Island, X v. Mueller. 



2. P. Dallachiana (after J. Dallachy), Benth. FL Austr. iii. 427. A 

 straggling shrub of 6 to 8ft., quite glabrous. Leaves elliptical or oblong, 

 acuminate, narrowed into a rather long petiole, mostly 8 to 4in. long, smooth 

 and almost shining. Flowers very small, in an ovate very shortly pedunculate 

 panicle, dense when first coming out. Calyx-limb slightly sinuate-toothed. 

 Corolla glabrous outside, bearded inside at the throat, about 1 line long ; 

 anthers exserted. Ovules ovoid. Fruiting panicle loose, divaricately trichoto- 

 mous. Fruits globular, about 3 lines diameter, the pyrenes not ribbed. Seeds 

 ruminate. 



Hab.: Eoekirigham Bay, Dallachy, and other tropical localities. 



Wood of a yellowish-grey colour, close-grained, and hatd.— Bailey's Cat. Ql. Woods No. 257. 



3. P. loniceroides (Lonioera-like), Sieb. in DC. Prod. iv. 523 ; Benth. Fl 

 Austr. iii. 427. A shrub attaining 12 to 15ft., the branches, foliage, and 

 inflorescence more or less rusty-tomentbse or softly pubescent, or rarely the leaves 

 at length glabrous above. Leaves ovate eUiptical or oblong, acuminate or almost 

 obtuse, narrowed into a petiole, mostly 2 to 3in. long. Peduncles terminal but 

 often appearing lateral from the elongation of only one branch of the fork 

 shorter than the leaves, more or less cymosely branched or almost umbellate'
