AD FLOBAM INDICAM (sALSAMIIfEiE). 113 



several having all the leaves opposite may be referred to B, and 

 others with them all alternate to D, E, F, and Gr. There are great 

 difficulties attending the discrimination of the allies of I. latifolia, 

 Roylei, and sulcata. I. Gougliii may be referred to Umiellata or 

 Lateriflorcd, or even to BacemoscB. 



D. Unieloe-S). Folia omnia altema. Peduneuli 1-flori. (Sp. 34- 



47.) 

 Another rather artificial assemblage, of which I suspect only 

 a few (J. Balsamina, scahriuscula) have invariably 1-flowered pe- 

 duncles, and of which the others, when 2-flowered, may be referred 

 to E. I. leptojpoda is probably a state of L latifolia, I. capillipes 

 is a curious species, very unlike the others. 



E. LATEEirLORJE. FoUa omnia alterna, subdistantia, non omnia 



approximata v. subverticillata. Pedunculi solitarii v. fascicu- 



lati bracteolati, secus caulem elongatam plerumque axillares 



(non axillis supremis tantum siti), patentes, 2-6-flores. Mores 



racemosi, non umbellati. (Sp. 48-64.) 



A very natural group, if confined to those species which, like 



I. macrophylla, glanduUfera, serrata, scairida, &c., have elongated 



stems and peduncles from axils of many of the rather distant leaves ; 



but with regard to the others, several of them present specimens 



which fall naturally into Gr, and others when 1-flowered would be 



sought for in D, The group is divisible into several sections. 



F. Umbellate et Capitat-S]. i<b?^<? omnia alterna, versus apicem 



caulis conferta. Flores apices versus pedunculi elongati bre- 

 vissime racemosi v. umbellati v. corymbosi. — (Bractese pleris- 

 que conspicuse.) (Sp. 65-78.) 

 This group embraces certain closely allied peninsular species 

 with simple stems and very short, many-flowered inflorescence, of 

 which I. linearis and wnbellata are types ; but others are branched 

 and few-flowered, as I. grandis, campanulata, &c., and may be re- 

 ferred to E. 



Gr. Eacemos^. Folia omnia alterna. Fedunculi plures, elongati, 

 multiflori, demum folio longiores. Flores racemosi, interdum 

 verticillati, v. fasciculati. (Sp. 80-95.) 

 A very natural group on the whole, the principal exceptions 



being I. longicornu and I. urticifolia, some forms of which may be 



referred to E ; I. Walkeri is closely allied to I. Jerdonicd ; J. cor- 



nigera to certain species in E.
