broad compact symmetrical head, 

 leaves with the narrow leaflets of Sor- 

 bus discolor, and the compact, slight- 

 ly convex flower-clusters of Sorbus, 

 Aucuparia, as broad as those of S. dis- 

 color. The fruit is pinli and in color 

 unlike that of any of the species of 

 Sorbus. This hybrid is the Iiandsom- 

 est Mountain Ash in the collection 

 where it has grown more rapidly than 

 most of the species of the genus; and 

 there now seems to be every reason 

 to hope that it has enabled the Arbo- 

 retum to add to the list of ornamen- 

 tal plants hardy in New England an- 

 other tree as valuable as Malus arnol- 

 diana. This tree, which appeared in 

 the APlwretum many years ago, has 

 been so often noticed in these Bulle- 

 tins that it is not necessary now to 

 more than repeat the fact that it is 

 probably a hybrid of Malus floribunda 

 and some other Asiatic Crabapple, 

 probably oue of the hybrids of Malus 

 baccata; and that, in the judgment of 

 many persons, it is the handsomest 

 Crabapple now cultivated. Mains rub- 

 rifolia is the name which will be given 

 to the hybrid Crabapple recently men- 

 tioned in Bulletin No. 5 of this volume. 

 It finds a place in the list of Arbore- 

 tum hybrids because it is now known 

 that it was either raised from seeds 

 gathered in the Arboretum or that it 

 was a seedling pulled up from the 

 neighborhood of the Arboretum plants 

 of Malus Niedzwetzkyana. These Ar- 

 boretum hybrids show that new plants 

 may appear spontaneously in any large 

 collection of cultivated plants, that 

 such spontaneous hybrids are some- 

 times valuable and that others, al- 

 though interesting, can add little or 

 nothing to the beauty of gardens. They 

 show, too, that if the fertilization of 

 the flowers of one plant by the pollen 

 from the flowers of a different spe- 

 cies or hybrid can produce such re- 

 sults as Sorbus arnoldiana and Malus 

 arnoldiana, systematic and intelligent- 

 ly directed hybridization might with 

 the abundant material here produce 

 plants more beautiful than any now 

 known in our gardens.
