The author concludes his paper with the description of a new and 

 nearly-related genus, founded upon a plant which was introduced 

 from New South Wales into the Royal Botanic Garden at Kew, in 

 1823, and which is remarkable for its unenclosed embryo, and for 

 the singular appendages, similar to those of Parnassia, which are 

 seated at the inner base of the sepals. The following is the descrip- 

 tion of this interesting genus : — 



TRIPLADENIA. 



Perianthium 6-phyllum, petaloideum, patens, aequale, deciduum : foliolis 

 aestivatione involutis, basi biappendiculatis ! sessilibus. Stamina 6, 

 toro, nee basi sepalorum inserta. Anther oe erectoc, extrorsse, bilocu- 

 lares, duplici rima longitudinali dehiscentes. Ovarium liberum, trilo- 

 culare : loculis biovulatis : ovulis campylotropis, collateralibus, erectis. 

 Stigmata 3, recurvata. Pericarpium subbaccatum, 3-loculare, 3-valve, 

 loculicido-dehiseens : loculis 1 — 2-spermis. Semina sub-orbiculata, bine 

 convexa, inde angulata, v. concaviuscula, glabra, nitida, colore suc- 

 cinea, hilo maxime fungoso-strophiolato, chalaza orbiculata concava 

 fusca, raphide dimidio seminis vix breviori, elevata : testa tenui, mem- 

 branacea ; albumen copiosum, corneum, album. Embryo oblongus, 

 albus, hinc convexus, indeplaniusculus, more Graminum extra albumen 

 locatus, eodemque facie plana, applicatus, funiculo maxime strophiolato 

 solummodo obtectus ! extremitateradiculari (cauliculari) paullo latiori. 



Herba (Novae Hollandia 1 ) perennis, rhizomate multicejrite, caulibus subsim- 

 plicibus multangulis, foliis ample xicaulibus ovato- lanceolatis, peduneulis 

 axillaribus solitariis unijloris infra medium articulatis invo/ucelloque 

 3-phyllo munitis.
