to P. obtusa, from wliicli however its labellum at once distin- 

 guishes it. The labellum a)«d Hower are like those of P. praecox, 

 the leaves, stem, and papillose surface are more like the charac- 

 ters of P. reflexa. 



Since a perfect series of gradations exist as regard size of 

 flower, length of point of labellum, size and acuminate character 

 of leaves, and scabrous or glabrous character of stem and leaves 

 between P. leflexa and P. praecox, Lindl., the latter species 

 must be reduced to a vaiiety of P. reflexa. P. obtusa, 11. Br., 

 seems to be distinct, especially as regards the obtu.sely oblong 

 shape of its labellum.

Tysonia piiyllostkgia, F. v. M. (Compositae) = Swinbukma 



PHYLLOSTEfJIA, F. V. M. 



This plant was descril)ed in the Chemist and Druggist of 

 Australia, Oct. 1, 1896, at the time of Mueller's death. A 

 description but no specimens are in the Herbarium. The latter 

 were apparently claimed and retained by Mueller's Executors. 

 Mueller was evidently unaware of the existence of a prior generic 

 name of Tysonia Bolus, Boraginaceae, represented by one African 

 species. Mueller's name therefore may be replaced Swinburnia 

 phyllostegia, the generic name commemorating the services of 

 the present Minister of Agriculture to Botanical research. 



Verticordia Pritzkli.i, Diels. Fragm. Phytog. Austr. 

 Occid., p. 401. 



Under this name Diels and Pritzel include the plant recorded 

 as V. humilis, Benth., of the Elder exploring expedition (Trans. 

 Roy. Soc. 8. Aust. XVI, p. 353). The latter identification was 

 certaiidy incorrectly, since the specimens have bearded and not 

 glabrous styles, but the style is not capitate as shown in Diel's 

 figure but with an obtusely linear point. In other respects the 

 specimens tally closely with Diels' description so that their flgure 

 of the style may have been incorrectly drawn.
