grass than H. murinum. Spike on a long peduncle dense = cylin-

scabrous not ciliate The glume and palea glabrous. Awns 
shorter than in H. murinum.—H. pratense, Huds.; Reichb. Ic. Fl.

Tasmania, but orte = » there established. 
Crass III. ACOTYLEDONES or CRYPTOGAMS. 
No real flowers, that is, neither stamens nor pistils nor true seeds, 
the reproduction carried on by means of minute often highly micro- 
scopic granules called spores. 
The only orders here included are the higher VASCULAR Cry PTOGAMS, or Ferns 
and their allies, which have true stems e enclosing bundles of vascular tissue, and the

rmined or studied without the aid of special work o them, to condense 
which for the Australian Flora w o formidable a Lon for me to undertake 
at my age. Neither is the history "d entered into of th y various Video. es by 
which the spores are developed in the Orders described, or a the in modiate 
er of their plant life from the spore ei the perfect plant ; this inquiry pere to 
he domain of Vegetable Physiology, and requires nb mari ôf living individuals 
with the aid of works specially devoted to the subject. In Cryptogams, as in 
Flowering Plants, their life history can be investigated neither in feld excursions 
nor from dried specimens, and therefore does not come into the special scope of 
local Floras. 
Order. CXLV. LYCOPODIACEZ.

spike, either all similar or of two kinds, larger ones macrosporangia
