2 THE JOrEXAL OF BOTAXY 



Tin* corolla -character, however, is not in itself a safe criterion ; I have 

 found considerable confusion in more than one European herbarium in 

 this retT^ard — many true it'<'/ //(//V^-si)ecies, with shortly-toothed calyx- 

 lobes, ixnng releijated to Aniaralia, evidently on account of the 

 sliape and greyish silky covei.-ing of the corolla Avhen di-ied. These 

 " Aniaralioid '*' Kandias are dealt with at the end of the present 

 paper. 



The calyx-lobes of all the species of Bandia and Oardcnia which 

 have come" under my notice are either shoi-t and tooth-like, or, if 

 elongated, are rektiveh' verj'^ narrow and mutually distant, and, in 

 any case, valvatelv arranged in the bud ; wdth one exception, namely, 

 Ranilia pnuhdijlora K.' Schum. (in Engler, Pfl. Ost-Afr. C. 380) ; 

 this has rektively broad calyx-lobes, dextrorsely contorted in the bud. 

 This species I propose to transfer to Amaralia, a suggestion supported 

 by the shape and indumentum of the corolla. 



M. Hua {loc. cif.) recognizes live species of the genus, which, as 

 we have seen, he calls Sherhournia, and gives a valuable discussion 

 of the genus and lucid descriptions of the species ; but I am unable 

 ti» agree with his conclusions entirely, as wnll api^ear in the systematic 

 account of the species which I proceed to submit. It would appear 

 that M. Hua has been somewhat l\andicapped by paucity of material ; 

 but his carefully pre])ared account lias been of very great service to 

 me in my own investigation. He says, truly, " Les cinq especes que 

 nous venous d'enumerer ne sont probablement pas les seules du 

 genre . . . qui se trouvent en Afrique tropicale." 



1 have found that the principal critical features determining the 

 species are the venation of the leaves, the size and colours of calyx 

 iind corolla, and the nature of the fruit-surface. Two species, 

 A. Buniinf/ii and A. 2iencluli-flora are distinct in their tree-habit, 

 the rest b«Mng scandent shrubs. 



The distrilnition is of interest, and supports, more or less, the 

 delimitations of the species. A. Sherhournits occurs westward to 

 Sierra Leone, but its most eastern and at the same time most southern 

 limits are in the Central Cameroons (Yaunde). A. lieinsioides has 

 a similar westward distribution, but claims an isolated home in 

 Central Africa, in Monbuttu and Niam-Niam lands. The allied 

 A. hii/nonic/'Jlora seems to be essentially an Angolan plant, although 

 M. Hua relegates a Congo specimen (loc. cit. 896) to this species. 

 I have had, unfortunately, no opportunity of examining this plant ; 

 but its ilower-colour, "rose brunatre," suggests the possibility that it 

 may be a distinct s])ecies. In any case the plant was collected no 

 further north of its original place in Angola than Kifcabi (French 

 C(»ngo), where the i)resence of any Angolan species would not be 

 sur])rising. All the si)ecimen8 of A. calycina (in the restricted 

 sense) were gathered in Sierra Leone. A. Zankeri occurs from Benin 

 in the west to Bipinde, in the Cameroons, in the east ; the Talbots 

 liave j)rovided several excellent examjiles of this species from Southern 

 Nigeria. A. Millruii has not been found outside Lagos ; A. Jlunua 

 is South-Nigerian. A. licndidijlora, one of the two tree-species, is 

 East-African. The remaining s]>ecies are based upon single specimens ; 

 A. nn.,t;.n;:. H il,..,. < .pr,-ies. was collected in Gola, Liberia:
