THE GEXrS A^rvRlLTA 8 



and A. micrantha, with quite small red flowers, was found by 

 E, W. Foster in Oloke Meji, Southern Nigeria. 



The genus is thus confined almost entirely to Western Tropical 

 Africa, Upper and Lower Gruinea, from Sierra Leone, through the 

 various districts along the coast, to Angola, the exceptions'' being 

 provided by A. heinsioides, which we have found in Central Africtr, 

 and A. penduliflora, in East Africa, 



I proceed to furnish a systematic account of the ten species which 

 I have had an opportunity of examining ; this I preface with a 

 clavis. 



AilARALIA. 



Erect plants (trees or shrubs), with smooth fruits. 



Calyx-lobes barely 1 cm. long ; leaf acute at base ; fruit 



narrowly ellipsoidal (East Africa) 1. penduliflora. 



Calyx-lobes over 2 cm. long ; leaf cordate ; fruit globose 



(Liberia) 2. Biuitinrjii. 



Climbing shrubs. 



Calyx-lobes over 15 mm, long. 

 Fruit smooth, unribbed. 



Corolla 3-4 cm. long, or more. 



Leaves acute at base, youngest relatively narrow... 3. Sherhoumiae. 

 Leaves cordate, broadly ellipticaL 



Corolla-tube less than 4 cm., purplish ; calyx 



purple, with broad obtuse lobes 5. hignoniaefloi'a. 



Corolla-tube over 4*5 cm., white outside, with 



rose lobes ; calyx-lobes narrow acute 6. heinsioides. 



Corolla barely 2 cm. long 4. calycina. 



Fruit prominently ribbed. 



Secondary leaf- veins 5-6 pairs. 



Young leaves small lanceolate, very acute 7. Huancu 



Young leaves large elliptical, not markedly acute. 



Fruit very narrow, often curved 8. Millenii. 



Secondary leaf- veins 10 pairs 9. Zenker i. 



Calyx-lobes barely 7 mm. long, corolla correspondingly 



small 10. micrantha. 



A. {Sherbournia) Brazzaei (see below) is unknown to me. 



1. A. PEXDULIFLOEA, nom. nov. Randia penduliflora K, Schum. 

 in Engler, Pfl. Ost-Afr, C. 380. 



East Africa : Derema, Volkens 127 ! Amani, Kerh, Amani 394 i 

 Hb. Mus. Brit. 



The Amani plant, according to the MS. on the label in the National 

 Herbarium, was distributed as Randia sericacantlia K, Sch. This 

 name appeal's as a nonien nudum, published bv Engler in Notizbl. 

 Bot, Gart. Berlin, iii. 84 ; but in any case the specimen cited is 

 s])ecifically identical with the Derema plant. The species is readily 

 distinguished by the tree-habit and small calyx. 



2, A. Buntingii, sp. n. 



Arbor ramulis glabris gracilibiis rectis Lnevibus ; folia chartacea 

 obovata 12-20 cm. x6-r)-9 cm., leviter acuminata basi cordata, supra 

 glaberrima subtus in venis obscuriuscule sericea, venis secundariis 

 utrinque 6. Flares in axillis solitarii ; cali/cis lobi oblongi, vix
