309. Mourtria parvifolia, sp. n., (Plate XXXVI.) foliis sessilibus ovatis vel ovato-lanceolatis 
acutis basi cordatis, pedicellis solitariis geminisve axillaribus bracteatis calyce brevioribus, calycis 
laciniis acutis reflexis, ovario uniloculari—Bay of Honda, Veragua. 
Frutex glaberrimus. Rami tenues, teretes, ramosissimi. Folia arcte sessilia, sesquipollicaria, subcoriacea, costa 
subtus prominenti, venulis vix conspicuis, punctis crebris nonnisi in folio juniore pellucidis, Squamule ad basin 
ramulorum juniorum et pedunculorum 2, parvee, acute, rigidule. Pedunculi 1}-2 lin. longi, bractea lanceolato- 
subulata medio instructi. Flores quam in ceteris speciebus multo minores. Calyx per anthesin campanulatus, 
parte libera longa, limbi lacinie ovato-lanceolatw, (colorate ?), demum reflexo-patentes. Petala angusta, 
acutissima, lacinias calycinas superantia. Stamina 10. Filamenta petalis duplo longiora. Anthere oblonge, 
loculis apice rima brevi dehiscentibus, connectivo crasso calcarato. Stylus stamina equans, filiformis, superne 
attenuatus, summo apice truncatus et tenuiter stigmatosus. Ovarium in fundo calycis erectus, perfecte unilo- 
cularis. Placenta centralis e fundo ovarii elevata ad tertiam partem cavitatis attingens, infra apicem ovulifera. 
Ovula 6 vel 8, supra basin lateraliter affixa, oblonga, erecta. Fructus junior intra calycis basin grossificatum 
inclusus, calyce igitur urceolato. Bacca matura (quam ipse non vidi) teste Hindsio atropurpurea, sapore 
dulcidulo grato. Semen unicum, testa ossea. 
This species has certainly the unilocular ovarium originally attributed to the 
genus by Jussieu and others, whereas in M. pusa, and all the Brazilian ones which 
I have examined, it is completely two or more celled, as described by Gardner.
