Prasophyllum Tkppkri, F. v. xM. 



This name is accepted as valid in the Kew Index, although 

 in the reference given (Tepper's Plants of Ardrossan, Oct., 1880) 

 the name occurs practically as a nomen nudum without p)roper 

 description, and no subsequent publication appears to have been 

 made. Owing, perhaps, to this fact, many specimens of another 

 later species {P. fusco-viride, Reader, Vict. Xat., 1898, p. 16-3) 

 were placed under this species. Only a single specimen of P. 

 Tepperi exists at the Herbarium, whereas F. fusco-riridf 

 appears to have a much wider range. To avoid future error. 

 Mueller's MS. description is published herewith, without altera- 

 tion or amendment. 



" Prasox)hyllum Tejjperi, Diff. a P. brevilabre, folio defi- 

 ciente, floribus minoribus, germine turgidiore, sepalo dorsali 

 latiore ; an var. ? 



" Flores viriduli. Sep. dorsale lanceolato-ovatum, brevi- 

 acuminatum ; sep. 2 inferiora (resupinatione-superiora, lanceo- 

 lata, sensim acuminatji, semiconnata. sepalo dorsali paulo 

 longiora, Sep. infer. (Pet.) lineari-lanceolata, sepalis exterioribus 

 breviora, labellum aequantia ; lab. brevissime unguiculatum 

 inarticuL, rhombo-ovatum, acuminatum, undulato-crispulum." 



Yorke's Peninsula, Tepper. 410. 



Prasophyllum fusco-viride (Header) differs in the following 

 respects from Prasophyllum Tepperi (F. v. M.) in: — 



1. The long circular sheath which completely surround* the 

 inflorescence in P. Tepperi is absent in P. fusco-viride, in which 

 there is a simple short bract at the base of the inflorescence. 



'1. The flower of P. Tepperi is much larger, about twice the 

 size of P. fusco-viride. 



3. The lateral sepals in P. Tepperi are united for fully half 

 their length, whilst in fusco-viride they are only united at the 

 extreme base. 



4. The dorsal sepal in P. Tepperi is almost ovate, while in 

 P. t'usco-vi ride it is relatively much narrower. 



5. The labellum of P. Tepperi is very shortly stipulate, and 

 not articulate, and in P. fusco-viride the stalk of the labellum is 

 very pronounced, and it is distinctly articulate. 



■6. The i^redominant colour of the petals of P. Tepperi is 

 green, and of P. fusco-viride is purple.
