Eggleston : Crataegi of Mexico and Central America 503 



flower by Humboldt and is finely described and figured by Kunth 

 in the Nova Genera et Species ; but flowering material of closely 

 allied species of Crataegi furnishes very unsatisfactory data for de- 

 termination and should be reinforced by mature fruidng material 

 whenever possible. Dr. Rose's Jalapa plant supplied immature 

 fruiting material for me ; and last fall, Dr. Pringle collected mature 

 fruit at Honey Station, Hidalgo (this station is within a mile or 

 two, at least, of Humboldt's locality. Real de Moran). 



My purpose in this article is to describe the wild species of 

 Mexico and Central America but my final treatment of the group 

 will require also a good deal of notice given to the different forms 

 raised in and described from the various European botanical 

 gardens. I have no evidence that either C, pubescens or C stipti- 

 losa has ever been cultivated in botanical gardens but in the early- 

 thirties C. mexicatia (C. stipulacea Lodd.) was of much interest to 

 the English gardeners and there was some controversy at the time 

 in regard to when and by w^hom it was introduced. The evidence 

 seems to point to the fact that it must have been received in Eng- 

 land from two sources in 1824 or a few years before that (see 

 Gard. Mag. 9: 496, 6^0 ', 11 : 473, 583. — G. Don, Gen. Diet. 

 2 : 598. — D. Don, in Sweet, Brit. Flow. Gard. 6 : 300). From 

 England it was introduced to the continent. It does not seem to 

 have been raised in the United States, although it might easily be 



5t. Louis south. Of the garden species 

 ra Smith. C. Carrierei x Carriere, C. 



grown from Washington or St. Louis south. 

 C. lobata Bosc, C. grandiflora Smith, C. Ca 

 Lavallei Herincq, and C. grignojiiensis Mouillefert, I have seen 

 fresh fruiting material of only C. Lavallei; this was sent me last 

 fall from Segrez, France, by Mr. Lavallee and might well be a 

 hybrid between C. mextcana and C, Crus-galli, as it has been 

 called. The colored plates of this- and C. Carrierei are much 

 alike and seem to me to represent practically the same form. C. 

 grandiflora Smith and C. lobata Bosc may be Mexican species or 

 at least partially derived from them, but these are doubtful points, 

 needing more careful investigation. However, I have not sufficient 

 knowledge of these species as yet, having but recently seen some 

 of the important literature on the subject. 



The genus Crataegus, south of the United States, seems con- 

 fined to the tablelands of Mexico and southward through the
