Opereniaria liberiflora F. v. M. (B. Hl. 437 sub FElenthranthes F. v. M.). 
Cum O. acolytantham cum O. vaginata Lab. affinitate arctissima con- 
junctam esse nemo dubitaverit, flores liberos (non concretos) ad genus 
proprium constituendum non idoneos esse apparet. Ifaque genus illud 
Eleuthranthes F. v. M. ex Benth. cum Opercularia esse contrahendum et 
Eleuthranthi opercularinae F. v. M. nomen > Opereularia liberiflora F. v. M.« 
(Fragm. IV. 92) esse reddendum censemus. 
Opercularia vaginata Labill. (B. HL 433). 
Polymorpba eum O. spermacocea formis intermediis conjungitur. Ares 
geographica ampla videtur: habemus a distr. Eyre pr. West River in 
graniticis (D. 4810) ad distr. Irwin, ubi pr. Mingenew cam vidimus in 
lutosis herbosis (D. 3606). 
Opereularia spermacocea Labill. (B. IIT. 433). 
Crescit in distr. Irwin in dunis regionis calcareae pr. Geraldton 
(D. 3206) eodem modo quo O. vaginata in distr. Darling utitur. — 
Meridiem versus per regiones arenosas pr. Esperance Bay (LABILLARDIERE 
in hb. Berol.) distr. Coolgardie invadit, ubi vidimus pr. Coolgardie in 
fruticetis aridis arenosis fruct. m. Oct. (D. 5834). 
Typus a cl. LAsittAnptng Nov. Holl. Pl. I. 35, tab. 46 descriptus fere 
glaber; specimina magis interiora magis scabrido-pilosa oriuntur. 
Opercalaria hispidula End). (B. TI. 436). 
Hab. quoque pr. King George Sound in silvaticis umbrosis solo 
granitico fl. m. Sept. (D. 4364) atque in distr. Eyre usque ad Esperance 
Bay progreditur, ubi vidimus in fruticetis densis collium litoris graniti- 
corum (D. 5366). 
Forma (?) O. pawcifloram Endl. referens, sed omnino glabra crescit 
in distr. Darling pr. Swanview in collibus glareosis flor. m. Jul. (D. 3799). 
Opereularia echinocephala Benth. (B. III. 436). 
Stirps rara videtur. Observavimus in distr. Darling pr. Mundaring 
in glareosis lapidosis fr. m. Dec. (D. 2016) 
Üpereularia apieiflera Labill. (B. HI. 436). 
Crescit in distr. Darling pr. Parkersville inter frutices densos solo 
humoso subhumido fruct. m. Dec. (D. 1654). 
Campanulaceae. 
Verbreitung: Die Campanulaceac haben blütenmorphologisch keine 
wesentliche Sonder-Entwicklung in Westaustralien genommen, während ihre 
vegetative »Anpassung« eigentümliche Formen dort geschaffen hat. Die 
meisten Arten sind über größere Teile Australiens verbreitet, und ihnen 
schließen sich die endemischen Formen gewöhnlich aufs engste an. Wahlen- 
bergia gracilis, Isotoma petraca und mehrere Lobelia sind auch in der 
Eremaea offenbar allgemein verbreitet.
