In habit this grass differs rather much from the common type of a 

 Poa, but there is a certain resemblance to P. abbreviata, and also to 

 P. glauca, var. arenaria, in the company of which it grew. I think 

 it is most nearly allied to P. abbreviata and the specific name has 

 reference to the difference from that species in the built of the shoot- 

 system. This manner of growth which may be said to hold the middle 

 place between the caespitose and the creeping species of the genus, is 

 doubtless due to the quahty of the locality, loose moving sand. Gene- 

 rally a few leafy shoots and one or a couple of culms stood together 

 in a little group, and in digging out the plant, it was found, that the 

 rhizome-branches which were covered by sheaths of old leaves, converged 

 downward to a common point of origin. Sometimes rhizome-branches 

 would creep more horizontally for a while before they began to rise to 

 the surface. 



The leaves of the sterile shoots have rather narrow sheaths, and 

 are narrow, rather' stiff, involute. The sheaths of the culm leaves are 

 longer, very much inflated. Their lamina is very short, especially in the 

 topmost, where it may be represented only by a small point. Leaves 

 and culm are entirely glabrous. The culm is stiff, erect and leafy only 

 as far as the middle.
