lanceolate, acute : base of corolla only very sparingly granu- 

 lar ; filaments more nearly ligulate than subulate, smooth and 

 glabrous, very short, of much less than half the length of the 

 much elongated anthers. 



Occurring in thickets, at Towner, N. Dakota, and collected 

 in fine specimens by Dr. Lunell, 21 July, 1908 ; apparently 

 distributed by him for 5*. ciliatum, the best that could have 

 been done by any botanist guided by nothing better than the 

 indefinitive and loose descriptions of that species that are in 

 all the books. 



Nothing, however, at present existing in herbaria, whether 

 from North or South, East or West, has at all the characters 

 that mark conspicuously as new this present plant. 



Some Southwestern Mulberries. 



Almost fifty years since Mr. S. B. Buckley published a new 

 kind of mulberry bush from western Texas under the name 

 Morns microphylla (Proc. Philad. Acad. vol. for 1862, p. 8). 

 The leaves, as the name indicates, were very small for those 

 of a mulberry, and Mr. Buckley reported that the species was 

 not a tree, but a mere bush. It was the product of its dry and 

 over-heated southwestern desert environment. After this, as 

 in the course of events botanical exploration was carried 

 further westward by hundreds of miles, and into still more 

 starved and arid regions, that is, into New Mexico, Chihuahua 

 and Arizona, mulberry bushes, smaller and with still smaller 

 foliage were collected and .sent in as "Morus microphylla." 

 The name fitted, and that was enough — is always enough — 

 with the indifferent and indolent multitude of people botanical, 

 to warrant the application of Buckley's name to all of them. 



With not much less than half a hundred good sheets of 

 specimens of these things before me, I think I can not do 

 better than indicate some of the specific differences which I 

 readily detect in this aggregate of small mulberries of the 

 Southwest ; and, since the original description published by
