been detected m the Australian continent. B ™ is veQ- nearly allied to Cren, but differs from most species ot
a genua m the sobtap. spike, and most conspicuously in the erect bristle, hooked at the apex, which, arising
from c ose to the base of the ovary, projects from the mouth ot the perigynium. A similar organ, but not hooked

N at. O kd . XVI. GRAMINEÆ.
11ns extensive and important Natural Order is very scantily represented in Australia, where (including
Tasmania) only about 330 species have been found; hence, though one ot the largest natural family of
Mouoeotyledons, it here but little exceeds Oijperaeeee in numbers, and is very mneh smaller tban Legumi-
mem, Mgrtacex, Compodtæ, or Preteaeex. Altogetber the Grasses form less tlian one-twentieth of the
whole flowering plants of tins part of the globe, a very miicb smaller proportion thau they do in any
other country of equal area. The Order varies much in relative numbers to other plants in the different
quarters ot the continent, the Tasmaniau proportion rising to one-sixteenth of the flowering planis ot that
Island. The Swan Eiver proportion is very much smaller, and the tropical greater.
In the determination ot the Tasmanian Qraminex, I have received very great assistance from my
friend Colonel W. Munro, through whose remarkable knowledge ot this difiicult and extensive Order of
plants, many of my doubts and perplexities have been solved.
