Some southwbstsrn mulberries. Ii3 



Buckley is too meager, and leaves out of the account some 

 good points, I attempt at the outset to give a new description 

 of it. 



Morns microphylla (Buckley, 1. c). Twigs of the season 

 on mature fruiting branches of a light reddish brown and 

 obscurely puberulent, the branches glabrous : leaves of such 

 branches and branchlets without lobe or sinus, of ovate out- 

 line, though often distinctly inequilateral, 1/^ to 2^ inches 

 long, 1 to 1^ inches wide below the middle, at base not sub- 

 cordate but nearly truncate, crenate-serrate except as to the 

 abrupt and prominent entire apical point ; the texture very 

 firm, both faces almost alike green, the upper glabrous and 

 smooth, yet under a lens closely low-tubercular, the tubercula- 

 tion absolutely blunt as well as low ; lower face of a rather 

 more vivid green, roughish to the touch by the presence of 

 minute and sparse hispidulous hairs on the veins, and even 

 on the general face : petioles firm, /^ inch long or more. 



This description is drawn wholly from specimens obtained 

 near Austin, Texas, by Mr. F. V. Coville, 27 May, 1904. I 

 use them partly for the reason that they are the best specimens 

 of all that are in U. S. Herb, from western Texas, and there- 

 fore lend themselves best to careful diagnosis. That the 

 vicinity of Austin is the original station for Buckley's species 

 I dare not say, for the reason that that author gives no closer 

 geographic limit than "Western Texas." True, there are 

 Buckleyan specimens at hand that were collected by him at 

 Austin in 1881, and at that time sent to Dr. Vasey at Wash- 

 ington. These, however, were not type specimens, collected 

 as they had been almost twenty years after his publication of 

 the species. They are poor fragments : but they are plainly 

 of the same species of which Mr. Coville gathered his excellent 

 material. Nevertheless, what Buckley's original of 1862 may 

 have been, and whence he had it, that is, from what particular 

 station, I have no means of ascertaining. Also I doubt not 

 that, having once established a species, he afterwards referred 

 all western mulberry bushes to that, without discrimination. 

 The original description has in it a vagueness that gives rise
