THE JOURNAL OF BOTANY 



Leucospermum R. Br. = Uiastella Knight (partly). 



Mimetes R. Br. 



Sect. i. Eumimetes Encll. = Mimetes Salisb. 



Sect. ii. Pseudomimetes Endl. = Diastella Knight (partly). 



The Index Kewensis takes us no further than Bentham and 

 Hooker, as the following reductions given there will show : — 

 DIASTELLA Knight = Leucospeemum R. Br. 



D. bryifora Kn. = L. puberum R. Br. 



D. ericmfolia Kn. = M. purpurea R. Br. 



D. Jmmifusa Kn. 



D. myrtifolia Kn. = M. myrtifolia R. Br. 



D. parilis Kn. = L. parile R. Br. 



D. serpyllifolia Kn. 



D. vacciniifolia Kn. = M. vacciniifolia (no authority). 



After a careful comparison of Knight's types of Diastella with 

 Brown's Mimetes I arrive at the following results : — 

 Diastella Kn. = Mimetes, sect. ii. R. Br. 



D. bryiflora Kn. = M. thymelcsoides R. Br. 



D. ericaefolia Kn. = M. purpurea R. Br. 



D. humifusa Kn. (no specimen seen). 



D. myrtifolia Kn. = M. myrtifolia R. Br., var. /?. 



D. parilis Kn. = M. myrtifolia R. Br., var. a. 



D, serpyllifolia Kn. = M. divaricata R. Br. 



D. vacciniifolia Kn. = M. divaricata R. Br. 



All the authors dealt with above agree in subdividing Mimetes 

 into two very defined sections (Mimetes Salisb. and DiasteZia Knight), 

 but these sections differ so much in habit, structure, &c., that I have 

 split Brown's Mimetes into two genera, and have kept up the names 

 published by Knight. 



GENERIC differences. 



Mimetes Salisb. 



Habit Erect plants, rarely de- 

 cumbent. 



Inflorescence ... Capitula3-13-flowered, 

 partly hidden in the 

 axils of the upper 

 leaves, aggregated at 

 the end of the bran- 

 ches ; capitula oblong. 



Involucre-bracts Membranous or cori- 

 aceous, usually showy 

 and coloured. 



Style H-^i in. long, glab- 

 rous. 



Stigma f-3 lin. long, cylindric, 



linear, nodulose, or 

 sinuate at the junction 

 with the style (rarely 

 gradually tapering in- 

 to the style), some- 

 times swollen above. 



Diastella Knight. 



Prostrate shrubs, 

 rarely erect. 



Capitula many-flow- 

 ered, terminal, soli- 

 tary, rarely 3-nate ; 

 capitula subglobose, 

 often truncate. 



Somewhat leathery, 

 rarely conspicuous. 



2f -4f lin. long, hairy 

 below. 



|— J lin. long, subcla- 

 vate, gradually ta- 

 pering into the 

 style.
