in my mind to a suspicion that his species may have been an 

 aggregate at the very outset. Here also I must remark that 

 Mr. Coville had declined to eive his own fine specimens any

MORUS PANDURATA. Branches and leafy twigs slender, 

 somewhat flexuous, puberulent when young, later glabrate: 

 leaves on slender petioles of Y^ inch or more, subcordate-ovate 

 in circumscription, some without lobe or sinus, some contracted 

 in the middle and panduriform, their length 2 to 2>^ inches, 

 breadth toward the broad base 13^ to 1^ inches, abruptly 

 mucronate, evenly subserrate-dentate, the teeth acutely and

name microphylla is more appropriate ; so that the name has 

 long been a misleading one to those who knew something of 

 far southwestern mulberry forms in general. 



I must now give account of another sheet of Buckley's 

 specimens, also from Austin, gathered by him as early as 1875, 

 and sent to Dr. Vasey. They are twigs from another tree, 

 and are at an earlier stage of growth, being hardly out of 

 flower ; or else they represent a later flowering of perhaps a ''

of indument : petioles also the same : leaves of round-ovate 



circumscription, 2^ inches long, 2 inches wide, strongly 3- 



lobed and quite constantly of one pattern, the serrature more h 



sharp and truly serrate, not crenate-serrate, the apex equally 



an entire acumination : texture much thinner, and upper face 



very distinctly muriculate- or even strigose-scabrous ; lower 



face as in Mr. Coville's specimens save that the hispidulous 



roughness is more general and more copious. 



Despite the discrepancies as to texture and roughness of 

 foliage, which may be partly due to differences in age and 

 maturity, I assume that all these sheets of specimens represent 

 one species, and that probably the one to bear the name 

 microphylla by right of priority, though not by right of reason 

 and fitness.
