342 LI. ROSACES. (J. D. Hooker.) \_Eubus. 



ensis, Otto Kunze MSS. in Herb. Clarke ? R. paniculatus, Clarke in Journ. 

 Linn. Soc. xv. 140, not of Smith. 



Temperate Himalayas ; from KUMAON, alt. 7000 ft., to SIKKIM, alt. 4-7000 ft., 

 J. D. H. KHASTA Mrs., alt. 3-4000 ft. AVA and MARTABAN Hills, Kurz. DISTRIB. 

 Java. Naturalised and cultivated in the tropics and warm temperate regions; 

 flowers often double. 



Stems erect or inclined ; branches slender, glabrous, pubescent or almost villous, 

 as are the petioles and peduncles, sometimes crinite with long dark-brown spreading 

 simple or gland-tipped hairs (R. sorbifolius, Maxim.) ; prickles sometimes very 

 numerous, mostly straight on the stem and hooked on the petiole leaflets and in- 

 florescences. Leaves 2-5 in. long, bright green, never glaucous or white beneath ; 

 petiole slender, often prickly ; leaflets 1-2 in., rarely more, membranous or coriaceous, 

 sessile or petiolulate , stipules linear-lanceolate or filiform, long-acuminate. Flowers 

 f-1 in. diam. ; peduncles usually slender, prickly. Calyx glabrous or pubescent, not 

 prickly, tube small ; lobes acute or acuminate or hair-pointed, or drawn out. to a 

 serrated limb nearly an inch long; spreading in fruit. Petals orbicular-obovate. 

 Carpels excessively numerous, glabrous, on a villous receptacle. Fruit globose or 

 more often oblong ; drupes smaller than in any other species ; stone deeply pitted. 

 R. paniculatus, Roxb. (R. Eoxburghianus, Wall. Cat. 732.) from the Moluccas is 

 R. parvifolius, Linn. & Humph. (Amboin. v. t. xlvii.), and perhaps also R. fraxini- 

 folius, Poir. ; it has larger leaves and smaller calyx and fruit than rostpfolius. R. 

 Javanicus, Celebicus and others are in various respects intermediate, and all may 

 prove forms of one common Malayan plant. 



DOTTBTFUL SPECIES. 



R. HIBISCIFOLITJS, Focke Batogr. in Abhandl. Naturwiss. Verein, Bremen, iv. 197 ; 

 unarmed, stem smooth, floriferous branches slender and petioles puberulous, stipules 

 broadly linear obtuse deciduous, leaves petioled ovate or ovate-lanceolate cordate 

 long-acuminate 3-lobed unequally subincised-serrate hairy then glabrate above, 

 paler and puberulous on the nerves beneath, flowers crowded subfascicled shortly 

 peduncled forming a short narrow inflorescence, bracts ovate-lanceolate acute some- 

 times denticulate, calyx yellow tomentose cleft hardly to the middle, lobes shortly 

 triangular. Leaves exactly like those of R. palmatus, Th., flowers like those of 

 R. moluccanus. Nipal, Wallich in Herb. Copenhagen (Focke). I have no idea what 

 this species can be ; I find nothing like it in Herb. Wallich. 



K. HOFFMEISTERIANUS, Kunth $ Bouche Ind. Sem. Hort. Berol. (1817 coll.) 14, is 

 I suppose R. niveus, Wall. 



9. GEUni, Linn. 



Erect perennial herbs. Radical leaves crowded, pinnate; terminal leaflet 

 large ; stipules adnate to the petiole. Flowers solitary or corymbose, white yel- 

 low or red. Calyx persistent, 5-bracteolate ; lobes 5, imbricate or valvate. Pe- 

 tals 5. Stamens very many, crowded. Disk smooth or with radiating grooves. 

 Carpels many, on a long or short receptacle ; style filiform, elongating much after 

 flowering, straight or bent ; ovules ascending. Achenes many, on a dry recep- 

 tacle, each with a long filiform straight or bent terminal style which is often 

 hooked at the tip. DISTRIB. Temp, and cold regions of N. and S. hemispheres ; 

 species about 30. 



SECT. I. G-eum proper. Style in fruit hooked at the tip or below it. 



1. G-. urbanum, Linn.; Boiss. Flor. Orient, ii. 696; erect, sparsely 

 softly hairy, lower leaves pinnatisect, leaflets 9-11 with the alternate smaller, 

 upper sessile, flowers erect, head of hispid achenes sessile. G. Roylei, Wall. 

 Cat. 713. 



Western temperate Himalaya, alt. 6-11,000 ft., from MURREE to KTJMAON. DIS- 

 TRIB. Siberia and westwards to the Atlantic.
