214 Dr. J. D. Hooxer’s Enumeration of the Plants 
This differs from its congeners in the capitula being discoid, and in the 
scales of the involucre and of the receptacle not sheathing the flowers. 
169. JÆGERIA PROREPENS, Hook. fil.; piloso-pubescens gracilis, caule repente 
radicante parcé di-trichotomé ramoso, foliis sessilibus oblongis obtusis 
obscuré dentatis utrinque subhispido-pilosis, pedunculis axillaribus fili-

Hab. James Island, Charles Darwin, Esq. 
Caules 6 unc. longi, repentes, radicantes, ramis ascendentibus v. erectis. Folia uniformia, 
i unc. longa. Capitula 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. SPrLANTHES DIFFUSA, Hook. fil.; herbacea, hispido-pilosa, caule gracili 
prostrato ascendente subsimplici, foliis petiolatis ovatis acutis interdüm 
basi cordatis integerrimis utrinque hispidis, capitulis discoideis laté ovatis 
obtusis longé pedunculatis, involucri squamis uniseriatis oblongis obtusis 
dorso pilosis, floribus omnibus tubulosis hermaphroditis, styli ramis erec- 
tis, achzeniis omninó calvis, receptaculo columnari. 
Var. 8. minor, vagé ramosa. 
Hab. Charles Island ; var. 8. James Island, Charles Darwin, Esq. 
Caules tenues, 3 unc. ad spithamzum, ramis divaricatis elongatis. Folia 1-3 unc. longa, 
planiuscula, subcoriacea, utrinque pilis sparsis albidis hispida v. substrigosa, interdüm 
obscuré sinuata ; petiolis 2-4 lin. longis. Capitula parva, } unc. longa, juniora globosa 
demum elongata.  Receptaculi paleæ flores vaginantes, subscariosz, obtusze, dorso 
obscuré ciliate. Achznium atrum, glaberrimum. Corolle 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. CanysaNTHELLUM PUSILLUM, Hook. fil.; annua, glaberrima, caulibus gra- 
cillimis ramosis, ramis ascendentibus, foliis omnibus petiolatis ovatis
