214 Dr. J. D. Hooker's Enumeration of the Plants 



This differs from its congeners in the capituia being discoid, and in the 

 scales of the involucre and of the receptacle not sheathing the flowers. 



169. J^GERiA PROREPENs, //ooA:. ^/. ; piloso-pubcscens gracilis, caulc repcnte 

 radicante parc^ di-trichotom^ rainoso, foliis sessilibiis oblongis obtusis 

 obscur^ dentatis utrinque subhispido-pilosis, pedunculis axillaribus fili- 

 formibus folio sequilongis v. longioribus, capitulis parvis radiatis sub- 

 sphsericis, squamis involucri ovato-lanceolatis acutis fiores radii vaginan- 

 tibus, receptaculi paleis involutis, fl. i*adii ligulatis, ligula lata bifida. 



Hab. James Island, Charles Darwin, Esq. 



Caules 6 unc. longi, repentes, radicantes, ramis ascendentibus v. erectis. Folia uniformia, 

 ^ unc. longa. Capituia 2 lin. lata. 



Allied to the J. hirta, but a much smaller plant, of a different habit of 

 growth, and with leaves rounder at the base. 



170. Spilanthes diffusa, Hook. ^l. ; herbacea, hispido-pilosa, caule gracili 

 prostrato ascendente subsimplici, foliis petiolatis ovatis acutis interdiim 

 basi cordatis integerrimis utrinque hispidis, capitulis discoideis lat^ ovatis 

 obtusis longe pedunculatis, involucri squamis uniseriatis oblongis obtusis 

 dorso pilosis, floribus omnibus tubulosis hermaphroditis, styli ramis erec- 

 tis, achseniis omnin6 calvis, receptaculo columnari, 



f^ar. (3. minor, vage ramosa. 



Hab, Charles Island ; var. ^. James Island, Charles Darwin, Esq. 



Caules tenues, 3 unc. ad spithamsEum, ramis divaricatis elongatis. Folia ^-| unc. longa, 

 planiuscula, subcoriacea, utrinque pilis sparsis albidis hispida v. substrigosa, interdum 

 obscure sinuata ; petiolis 2-4 lin. longis. Capituia parva, ^ unc. longa, juniora globosa 

 demum elongata. Receptaculi paleae fiores vaginantes, subscariosae, obtusae, dorso 

 obscure ciliatae. Achaenium atrum, glaberrimum. Corollas dentibus 4-5 glanduloso- 

 incrassatis. Stamina inclusa, nigra. Styli ramis breviusculis, erectis, apicibus subacutis 

 recurvis. 



A very insignificant weed, though apparently undescribed: it differs from 

 the generic character of Spilanthes in the arms of the styles being erect. 



171. Chrysanthellum pusillum, Hook.Jil.; annua, glaberrima, cauUbus gra- 

 cillimis ramosis, ramis ascendentibus, foliis omnibus petiolatis ovatis 

 dissectis laciniis linearibus acuminatis, capitulis long^ pedunculatis hete-
