CONTRIBUTIONS TO BOTANY. 
both fertile and sterile, in Liriosma, in form and structure 
resemble those of Olax : and L. Gardneriana and the typical 
species have their three fertile stamens placed in an alternate 
position, between each second petal and their six sterile stamens, 
intermediate between them, which are of course placed opposite 
the six petals. With the exact number and position of the sta- 
mens in the other species we are not informed, but I believe that 
in this genus, as in Olax, the real normal number of petals is 
six, with six fertile and six sterile stamens, the former being 
always alternate with, the latter opposite to, the segments of the 
corolla. 
The following is an amended generic character of Liriosma, 
di’awn up from my own observations ; and after the enumeration 
of its species, I purpose subjoining some remarks upon the affi- 
nities of the order to which it belongs : — 
Liriosma, Popp. Hypocarpus, A. DC. — Calyx parvus, carnosus, 
cupuliformis, disco adnatus, margine libero, crenato, vel obso- 
lete 5-dentato, augescens, et ad fructum demum coalitus, eum 
tegens. Petala 6, sspe usque ad medium geminatim laxe 
connata, carnosa, sestivatione valvata, apice processubus toti- 
dem inflexa. Stamina fertilia 3, petalis alterna, dimidio bre- 
viora, et ante suturam cuj usque paris sita, e margine disci cu- 
puliformis orta ; filamenta complanata, pilis longis cottoneis 
barbata, demum glabra, libera, vel ad petalas imo ssepius laxe 
agglutinata, connectivo crasso lato continua ; anthera introrsse, 
ovatje, cordatae, 4-lobse, 4-loculares, 4-valves, valvarum mar- 
gine alterutro vicissim dextrorsum et sinistrorsum intrinsecus 
soluto, hinc longitudinal iter dehiscentes. Stamina sterilia 6, 
petalis opposita, et vix longiora, filamenta carnosula, longe 
barbata, demum glabra, apice appendiciformia et bifurcata, 
laciniis subulatis, acutis, tenuioribus. Pollen subglobosum, 
vesiculis 3 aequidistantibus notatum, integumentis tenuissimis. 
Discus hypogynus, cupuliformis, carnosus, calyce brevior et eo 
adnatus, ad marginem liberum inflexum petala et stamina suf- 
fulciens. Ovarium ovatum, per dimidium inferiorem disco cir- 
cumdatum, et illic glabrum, primo omnino liberum, cito ad- 
natum, superne conicum, glandula magna epigyna crassa car- 
nosa pilosa undique tectum, imo dissepimentis incompletis 
3-loculare, summo 1-loculare. Ovula 3, anatropa singulatim 
in loculis spuriis ab axi placentifero centrali (cionospermio) 
suspensa, apicibus in loculi summo iudiviso simul conniventia. 
Stylus simplex, inclusus. Stigma capitatum, sub-3-lobura. 
Di-upa baccata, ovata, monosperma, calyce adnato tecta, apice 
umbilicata. Putamen subtenue, coriaceum. Semen loculum
