Subsequently the Mexican hawthorn seems to liaA'e received 

 little attention from the horticulturist. It continued, however, 

 an cultivation, and probably some of the trees of the first 

 introduction are still in existence. K. Koch,* who in his 

 f ' Dendrologie '' devotes nearly- three pages to the discussion of it 

 under the names of Mespilus mexicana und J/, ifuhescensy observes 

 that he saw it in England as well as in France, adding that it is 

 4?ultivated in Mexico, and has become very variable in the shape 

 of leaves and as regards tomentnm and fruit characters. He

represented tlie cultivated form, and that of the Botanical 

 Eegister the wild. As we tnow it is practically certain that Don's 

 •iind Lindley's plant came from the same source. He also 

 anentions Loddiges' C. stlpulacea as a third form distinguished b}' 

 larger, slightlj- lobed leaves, and more or less persistent stipules, 

 ihe latter, however, a. character which he did not find constant in 

 the specimens which he saw himself. He f urtlier says that he also 

 found Mespilus pubescens, H. B. Iv., in cultivation in France; 

 but his description of it, and the fact that he refers to it 6^ .suh- 

 serrafa of Bentham, are not compatible with this determination. 

 Up to the early sixties there is no evidence that any Mexican 

 hawthorns were in cultivation in Europe except those of Lambert's 

 (Lord Xapier's) introduction; but about that time, according to 

 Iv. Koch,t the tree was reintrodvxced in what appeared to be the 

 wild state. No further reference, however, to this second intro- 

 duction has been found. The plant remained a rarity in gardens 

 to which little attention was paid. 



The following specimens taken from trees cultivated in Europe 

 «re at Kew: 



1. Tiondon Horticultural Society's Garden, 1838 (Herb. 

 Jienth.) sub Crataegus mexicana. Has long shoots with lobed 

 •leaves and large foliaeeous stipules. 



2. Chelsea Physic Garden. Three sheets (a) fruiting, leaves 

 eoarsely dentate to sublobed, sub C, Crus-gallty coll. Xov. 1899; 

 ■(/3) fruiting, leaves as shown in Bot. Heg. t. 1910, one long shoot 

 ^with coarsely dentate or sublobed leaves, and large stipules, as in 

 London Arboretum et Fruticetum, ii. 867, fig. 617, sub Crataegus 

 stlpulacea, coll. Sept. 1900; (7) flowering, exactly like Bot. Keg. 



1910, sub Crataegus stipidacea, coll. June, 1904. 



3. Paris, Botanic Garden; fruiting, leaves as in the Chelsea 

 specimen (y), but more lanceolate; long -shoot with stipules and 

 Jeaves as in Chelsea specimen (/3) ; barren short shoot with small 

 lanceolate leaves as in Bot. Eeg. t. 1910 (the lower branchlet on 

 the left side), very like Humboldt and Bonpland's figure, but 

 very sparingly hairy, all these collected 1899 and grown as C, 

 ^tipulacea, Steud. 



4. Kew, specimen received from Paris, 1891, no. 123, (a) barren
