The typical form of P. Crus-galli,as described above, occurs as a weed throughout 
the temperate zones of both he —— and more rarely in the tropics. All 
the South African specimens belon ng t the muticous state, except that alee 
by Baur near Shiloh. In B ( the junction-line of b 
and sheath is perfectly glabrous as usual, with the exception o of one lea tae ‘it 
is pubescent. I have not met with another case of this kind in the very numerous 
specimens of P. Crus-galli I uve examined, 
15. P. filieulme (Hack. in Bull. Herb. Boiss. iii. 377); culms 
decumbent, very slender and weak, up to 12 ft. long or longer, quite 
glabrous, many-noded, branched from most of the nodes, internodes 
exserted ; leaves almost perfectly glabrous ; sheaths thin, rather tight, 
at length dry, loosened and thrown aside, strongly striate, outer 
margin and mouth as well as the nodes minutely hairy (under the 
middle, 1-2 in. by 13-2 lin., flat, somewhat rigid, margins
