140 Rydberg: Notes on Rosaceae 



Garden, and in this the drupelets are eight to ten, but in Pringle's 

 specimen from Orizaba, they are twelve to twenty. The petals 

 are about as large as those of R. Schiedeanus. They were described 

 as pink, but they are often pure white. The following specimens 

 I refer to this species: 



Vera Cruz: Mirador, February, 1842, Liehmann 1688; hill 

 near Orizaba, February 3, 1895, Pringle 5925. 



Oaxaca: Totontepec, July 15, 1894, E. W. Nelson 773; be- 

 tween Juquila and Nopala, March 4, 1895, 2424. 



Rubiis Schiedeanus Steud. This differs from the preceding 

 species mainly in the toothing of the leaflets. In this the teeth are 

 very small, more distant or obsolete; in R. coriijolius they are 

 irregular, large and sharp, lanceolate, close together and directed 

 forward. I have seen only the following specimens: 



Vera Cruz: Mirador, February, 1842, Liehmann lyoj; near 

 Jalapa, April 2, 1899, Pringle 8086. 



Ruhus macro gongyliis Focke. In the original description Dr. 

 Focke does not cite any specimens. Some time ago I wrote him 

 and he kindly sent me a photograph of the type and wrote a 

 letter, from which I hereby give the following extract: "The best 

 characteristic for Ruhus macrogongylus is or seems to be the shape 

 of the fruit, which is elongated and consists of about 100 or more 

 perfect carpels. In the flowering branches most of the leaves are 

 quinate. The sepals are loosely reflexed in flower, afterwards 

 they embrace the base of the fruit. At first I saw such plants in 

 Donnell Smith Guatem., 4472, but the materials were not suf- 

 ficient for describing and naming them. I suggest that Donnell 

 Smith Guatem. 4178 will prove to be a form of the same species. 

 Some years ago I met with, in the Berlin Herbarium, several 

 flowering or fruiting specimens from Mexico. The panicle in 

 these plants was much more developed than in the Guatemala 

 ones, but I cannot distinguish leaves, tomentum, serrature, 

 flowers or fruits. I send a photo of a flowering branch from 

 Mexico. I think that the Mexican specimens represent the true 

 face of the species, and that those from Guatemala are somewhat 

 scraggy forms." 



The photograph was labeled ''Ruhus macrogongylus Focke, S. 

 Mexico Ex hb. Berlin." There was no indication of the collector
