422 Observations on some new 



Hab. — In Ceylona, prope Ugandamlej ; Klein. 



I have here followed Klein's views (as mentioned in Wight's 

 Contributions) of the structure of the capitulum, in preference to 

 those of Decandolle, as they agree better with my own observations. 

 Decandolle himself, before he was aware of Klein's memoranda on 

 the subject, appears to have had doubts if such were not the real 

 structure. 



Leucoblepharis, Am. (Compositse.) 

 Capitula innumera in glomerulum hemispheericum coacervata; 

 axi plana. Bractece sub glomerulo ovatee, mucronatse, foliaceae. 

 Capitula 8-flora, monoica. Receptaculum paleaceum, paleis conca- 

 vis. Involucrum oligophyllum. Flares exteriores 4, feminei, tubu- 

 losi, 4-5-dentati : interiores 4, masculi, apice latiores, 5-dentati. 

 Anther ae basi sagittato-subcaudatae. Stylus fl. masc. integer, apice 

 incrassatus. Achenia nigra, nitida, hinc plana, illinc convexa, mar- 

 ginibus dense villis albis longis erectis ciliatis ; fem. late-ovalia, ob- 

 compressa, angulo dorsali paullum albo-ciliato ; masc. angustiora, 

 dorso convexiore subglabro. Pappus conformis, paleis scariosis, plu- 

 rimis, flexuosis, inaequalibus, acuminatissimis, villis achenium mar- 

 ginantibus absconditis. 



Herbacea, glabra, simplex. Radix crassa, prcemorsa, lignosa. 

 Folia alterna, sabsessilia, elliptica. utrinque obtusa vel attenuala, in- 

 tegerrima, triplinervia. Glomerulus terminalis, solitarius, subses- 

 silis, bracteis involucralibus glomerulum super antibus. 



1. L. subscssile, Arn. — Blepharispermum subsessile, D. C. in 

 Wight. Contr. p. 12 ; Prod. v. p. 368 ; Wight. Cat. n. 1418. 

 Hab. — In Mysore ; lieyne. Prope Bellary ; Wight. 

 By comparing this generic character with that of Blepharisper- 

 mum, it will be seen that it differs very widely in the structure of 

 the achenium and pappus of the sterile floret, in which respect it 

 approaches much more to Athroisma ; but in that genus the angles 

 of the acheninm are merely ciliated at the apex, and the pappus 

 appears to be composed only of a few short hairs. The habit of 

 these two genera is also very unlike. 



Madaroglossa, D. C. (Compositae.j 

 This genus is said by Decandolle to be allied to Blepharipap- 

 pns of Hooker, but to differ by the ray having no pappus. From a 

 slight examination of specimens of both genera in Sir W. Hooker's 

 Herbarium, it seems that both these distinguished botanists have the 

 same in view; but that either ought to be separated into two genera.
