Gutenbergia| LXXI, COMPOSITA, 515 
Hvitia.—Corollas purple ; achenes obovoid, glabrous (or some- 
what setulose), without pappus. In elevated sandy pastures between 
Empalanca and Nene; fl. and fr. April and May (rainy season) 1860. 
Seen nowhere else in the district. No. 3998. 
Our specimens vary much in the shape of the leaves, those of No. 
3997 being oval, ranging up to 2 in. long by 1 in. broad, the upper ones 
alternate, the rest opposite and often with short young leafy shoots 
quasi-fasciculate in their axils ; the achenes are 3- or 4-gonous rounded 
on the back and with several very delicate or obsolete ribs ; they should 
be compared with G. leiocarpa O. Hoffm. in Engl. Pfl. Ost- Air, C.4 
p. 402 (1895), and are referred as above with some doubt.
