216 DR. J. D. HOOKER ON THE PLANTS 
Very nearly allied to the Indian ZL. terminalis, but the inflores- 
cence is lateral; and still more near to the American L. Canaden- 
sis, but the achenia have much broader wings ; it differs further 
from both in the shorter stigma. 
4. ELATOSTEMMA MONTICOLA, H. f., n. sp. 6-8-pollicaris, caule tenui 
pubescenti-tomentoso, foliis alternis breviter petiolatis oblique obo- 
vato-oblongis grosse serrato-dentatis utrinque sparse setulosis, supe- 
riore basi acuto, inferiore obtuso, nervis primariis 2-3, stipulis lanceo- 
latis, capitulis 9 subsessilibus depressis. 
Hab. Cameroons Mountains, alt. 7900 feet. (Fl. Dec.) 
Herba tenella. Folia 1-13 unc. longa, membranacea, puberula et setu- 
losa. Capitula 9 1-4 unc. diametro. Involucrum membranaceum, 
multilobatum, multiflorum, lobis oblongis ciliatis. Fl. 9 sessiles et 
pedicellati, conferti. Perianthii foliola lanceolata, setuloso-ciliata. 
Achenium ellipsoideum. 
A very common form of the genus, resembling closely several 
mountain Indian species. 
5. PILEA QUADRIFOLIA, A. Rich. Dioica, spithamea, glaberrima v. 
sparse pilosula, caule erecto ramoso gracili, foliorum paribus zequalibus 
graciliter petiolatis 3—4 unc. longis late ovatis acutis grosse crenato- 
serratis membranaceis, stipulis amplis late cordato-rotundatis ; fl. d 
in axillis glomerati, 9 axillis supremis dense paniculatim conferti.— 
Wedd. Monogr. Urt. 199. 
Hab. Cameroons Mountains, alt. 7000 feet. (Fl. Dec.) 
Species elegans, gracilis, lote virens. Petioli foliis subzequilongi. Folia 
basi 3-nervia. Stipule } une. longe. Fl. 3 in axillis plurimis caulis 
dense congesti, majusculi, 3-5-meri, perianthii lobis 1 v. pluribus 
longe aristatis. Fl. 9 in paniculas breves subterminales foliis 4 su- 
premis involucratas dense aggregati, perpusilli, breviter pedicellati. 
Perianthium foliolum 1 oblongum (cetera in fructu. evanida), achenio 
brevius. Achenium minimum, ovatum, compressum, subgranulatum, 
stigmate infra-apicali. 
The female of this plant (from Abyssinia) is well described by 
Weddell. The male has long stems and uniform leaves throughout 
the plant; and the female has much shorter stems, with very few 
leaves, of which the four upper are subterminal and form a whorl, 
the lower are (by arrest) smaller, all more or less toothed in our 
specimens, but apparently sometimes quite entire in Abyssinian. 
A very closely allied, but larger species, with more effuse female 
panicles in the axils of all the leaves, is sent by Mann, from 4000 
feet in Fernando Po.
