t. 5, 6; Benth. et Hook. Gen. Plant. i. p. 937; Benth. Fl. Austr. iii.

lycis tubus ovatus ; limbus minimus, vix 5-dentatus. Petala 5, ovalia, 
subacuta, æstivatione valvata. Stamina 5; antherw oblonge. Discus

compressus exalatusque v. transverse subteres ad commisuram longitu- 
dinaliter alatus, exocarpio membranaceo v. subcarnoso; pyrene a latere 
compresse, presertim ad commissuram induratz ibidemque utrinque 
suleate v. in loculos spurios vacuos producte. Semen oblongum. Al- 
bumen zquabile.—Frutices Australienses, plus minus stellato-tomen- 
tosi v. lanati, foliis alternis petiolatis indivisis subtus tomentosis ; 
stipulis nullis; umbellis paniculatis; bracteis parvis setaceis V. nullis. 
A genus so closely allied to Nothopanaz, that it can only be separated 
by artificial characters ; so that the latter, bearing the more recent 
name, may have to be merged into it. In 1863 I transferred it (Journ. 
of Bot. i. p. 280) from Umlellifere, where up to that time it had been 
placed, to Hederacee,—a view since adopted by various authors.

Fitzroy Island (Walter Hill!).
