84 Mr D. Don on the Characters of Darwinia, <^-c. 



invaluable Prodromus. I shall proceed to give a description of 

 the genus, and also the characters of the two species already 

 published. 



DARWINIA, Rudge. 

 Syst. Linn. DODECANDRIA MONOGYNIA. 



Ord. Nat. MYRTACE^, Brown. 



Calyx tiibulosus, obtuse pentagonus, coloratus : tubus e medio deorsum ovario' 

 avcte adhcerens ; dimidio superiore membranaceo, deciduo I/awa'dilatato-cam- 

 panulata, venosa : lirnbus 5-lobus : loiis subrotundo-cordatis, obtusissimis, 

 concavis, pellucido-puiictatis, festivatione imbricatis. Petala nulla. Sta- 

 mina indefinita (10 v. 15) limbo calycino inserta, ssepius per tria approxi- 

 mata, medioque sinus laciniarum occupante : filamenta brevissima, anguste 

 lineai'ia, complanata, glabra : anthercB subglobosre, biloculares, basi insertae : 

 loculis tumidis, rinia loiigitudinali dehiscentibus. Pollen pulvereum. Ova- 

 rium infennn, jientagonum, uiiiloculare : ovulo solitario, erecto. Stylus ca- 

 pillaris, exsertus, superne attenuatus, apice barbatus. Stigma punctum 

 pruinosum. Pericarpitim capsulare, monospeimum, pentagonum, apice 

 clausum. Semen etiam pentagonum, pericarpio vix dimidio brevius : testa 

 raembranacea, spadicea, extus scrobiculata ! albumen nullum. Embryo 

 erectus, cavitatem seminis omnino implens, angulisque ejusdem impressus, 

 obovatus, lacteus : cotyledones brevissimse, crassse, obtusre : radicula crassa, 

 truncata, cotyledonibus duplo longior, recta, centripeta. 



Frutices (Australasici) decumbentes, ramosissimi, foliosi. Folia sparsa, angusla, 

 pellucido-punctata, basi ramis articulata. Floras terminales, fasciculati (verun-- 

 tamen axillares propria dicti ), rosei v. albi, nunc paleis (foliis mutatis) scariosis 

 interstincti. 



1. D. foscicularis , foliis acerosis, receptaculo paleaceo, stylo flora ter 



longiore. 

 Darwinia fascioilaris. Rudge in Linn. Trans, ii. 299. I. 22. 



Hab. in Nova HoUandia. White., Paterson, Caley. fj (v. s. sp. in Herb. 

 Lamb.) 



Frutex decumbens, ramosissimua. Folia acerosa, uncialia. Flores copiosi, 

 rosei, paleis scariosis lanceolatis v. setaceis distincti. 



2. D. taxifolia, foliis acinaciformibus, stylo flore breviore. 



Darwinia taxifolia. Cunningham in Field's Geogr. Mem. p. 352. 



Hub. in No; a Hollandia. Caley, Cunningham, T"? (v. s. sp. in Herb. 

 I.amb.) 



Prutex decumbens, ramosissimus. Folia sparsa, in apice ramulorum conferta, 

 fasciculata, falcata, acinaciformia, mucronulata, vix ultra semunciaUa. 

 Flores pauciores, foliis raro mutatis interjecti. Caly.v albus. Stamina 10. 

 Pericarpium capsulare, monospermmn, pentagonum. Ccetera ut in genere ■
