could not be mistaken for any of our native grasses. The only 

 grass that grows here that even suggests it is a small dry and 

 stunted Dacfylis glomcraia — and this an introduced species. 



In order to give an idea of the occurrence of Cynosuriis echi- 

 nafus in the United States, the following list of herbarium mate- 

 rial will indicate its scarcity : 



* I. Gray Herbarium. Xo specimens from the United States. 



* 2. Xew York Botanical Garden, also none from the United 

 States. 



* 3. U. S. National Herbarium. 



California: I\Iarin Co., 1912, Eastwood.

Of the fovtr species now retained in the genus Cynosunts L., 

 only two are found introduced in the United States ; all are of 

 the Mediterranean region. C. crisfafits L. is sometimes cultivated 

 in this country, but is of practically no economic importance. 

 The other seven Linnean species are now referred to other genera. 

 Hackel says in Engler and Prantl (X'at. Pflanzenf. H. 2, yT,) : 

 '' C. echinatus L. in Siideuropa, Ackerunkraut."' C. cchinatus be- 

 longs to the section Phalona (which Adanson made a genus), 

 while C. crisfatiis is included in the section Eucynosurus. There 

 is a good figure of C. cchinatus in Engler and Prantl. Besides 

 the material from the United States, the following regions are 

 represented by collections in the U. S. National Herbariiun : 

 South America; Africa; New Zealand; Italy; France; Syria; 

 England; Switzerland; Spain-Portugal; Austro- Hungary-Bal- 

 kans ; and the Canary Islands. ^lacoim collected it as far back 

 as 1908 in Nanaimo, Vancouver Island.
