of M, adstringens. Tlie other hybrid is called "Red Tip Crab'' and is a 

 hybrid with a wild Crab from Elk River, Minnesota, as the female parent. 

 As M. ioensns is the wild species of that region, this hy})rid would be a 

 variety of M. Soulardii,

In examining Schneider's type of Mains docynioides I find that there are 

 3-5 ovules in each cell and that it should, therefore, be transferred to Docy- 



nia, though the resulting combination is ratlier unfortunate. This new 

 Docynia is so closely related to D. Dclavayi that some botanists may pos- 

 sibly not consider it sj)ecifically distinct, as the two types, though looking 

 very distinct, are apj^arently connected by intermediate forms. Docynia 

 docynioides^ however, may be readily separated from typical D. Dclavayi 

 by the absence of the dense white tomentum of the under side of the leaves, 

 by the thinner, not persistent leaves often, particularly toward the apex, 

 serrate or serrulate, by the smaller number of stamens, and ap|)arently 

 also by the smaller number of ovules, for Cardot (in Rev. Ilort. 1918, 131) 

 states that in Franchct's type the number of ovules in each locule is 8-10, 

 not 4 as described by Franchet, and Cardot for this reason transfers the 

 si)ecies to Cydonia (In which he includes Chaenomeles) as C. Dclavayi^ but 

 even if the number of ovules should be ten, this would not be a sufficient 

 reason to transfer the species to Cydonia or Chaenomeles, as it agrees in all 

 other characters, particularly in the structure of llie flowers, with the other 

 species of Docynia. The nund>er of ovules, too, in Cydonia and Chaeno- 

 meles is more than ten.

This handsome gaiden form is apparently a hybrid between C. japonica 

 and C lagcnaria, as already suggested by Zabel (1. c, see above). It dif- 

 fers from C. japoniea chiefly in the larger, but narrower, acute, more sharply 

 serrate, darker green leaves and in the larger flowers of deej) blood-red color, 

 and from C, lagcnaria in the pubescent young branchlets slightly verrucu- 

 lose the second year, in the smaller, generally obovate-oblong less finely
