which are evidently a bush-like form of this species." These 

 must also have been Prunus Watsoni* The varieties, Purple 

 Panhandle, Red Panhandle and Yellow Panhandle, were intro- 

 duced from Texas by F. T. Ramsey. Mr. Ramsey says that 

 eight or nine years ago he got a quantity of stock "from various 

 counties in the upper Panhandle proper" of Texas. Besides 

 the varieties named, he had another called Clarendon. He says 

 further : " I have been greatly disappointed in them here, and 

 have dropped them from my catalogue this year, for the one reason 

 that they did not grow large enough. This winter I have been 

 surprised to have several inquiries for them from parties who 

 bought them from me, on account of the enormous crops they 

 bore." 



It seems entirely possible that we may yet find ourselves in 

 possession of some valuable varieties derived from this species, 

 though no ve v ry sweeping recommendation could fairly be given 

 any variety now known. 



At one time and another I have heard a good deal of talk 

 about using Prunus Watsoni as a dwarf stock for working other 

 plums, but I never knew of an experiment in that line. The 

 tendency to sprout from the roots would be a defect in using 

 the plants for stocks. 



In Maryland, the young growth and blossoms, especially of 

 Strawberry, are severely damaged by the brown-rot fungus, 

 Monilia fructigena. In their original wild state, along the 

 Arkansas river, they used to be free from brown-rot, black- 

 knot and curculio, but I lived in that country long enough my- 

 self to see them attacked by both curculio and black-knot. 



The rivwlaris plum. The Towakong or Creek plum, 

 of Texas, is one of which I have no personal knowl- 

 edge, except from herbarium specimens. It was first 

 brought to notice by the botanical collector Lind- 

 heimer, and described in 1848 by Scheele as Prunus 

 rivularis in "Linnaea" (xxi. p. 594). This is a bushy 

 plant, three to six feet high, which Gray speaks of as 



* The supposition is correct. Both the Strawberry and the Kansas form are 

 Prunus Watsoni. L. H. B.
