this species in our Second Volume. 



Spec. Char. y $c. Leaves permanent, cuneated at the base, acutely 3-lobed at 

 the top. Lobes entire, or toothleted ; lateral ones shortest. Corymbs few- 

 flowered, erect. Fruit smooth, with the wings hardly diverging. (Don's 

 Mill., i. p. 649.) A diminutive slow-growing sub-evergreen tree ; native of 

 Candia, and of other islands in the Grecian Archipelago. Introduced in 

 1752. 



Description, $c. This species is seldom seen in British collections, and 

 then more frequently as a shrub than as a tree; but it is readily known 

 from all the others, and from A. monspessulanum, to which it makes the near- 

 est approach, by its being nearly evergreen ; and by the great variety of the 

 forms of its leaves ; and, according to the specific character, by the flowers 

 being erect ; those of A. monspessulanum being pendulous. In young plants, 

 the leaves are seldom much lobed ; and this, we suppose, has given rise to the 

 species or variety known in gardens as A. heterophyllum, which appears to be 

 only A. creticum in a young state. We are only aware of three plants of this 

 species which have assumed the character of trees in the neighbourhood of 

 London ; viz, that at Syon, figured in our Second Volume, which is 28 ft. high, 

 flowers freely, and produces seeds almost every year ; one in the Chelsea 

 Botanic Garden, about 8 ft. high, which has stood there since the time of Mil- 

 ler ; and a third, of equal age, which was in the Mile End Nursery, and which, 

 in 1834, was 10 ft. high. This last tree has since been sold, and removed to 

 the garden of the Rev. T. Williams, at Hendon, Middlesex. This species is 

 generally propagated by layers ; though it might, probably, be grafted on the 

 Montpelier maple. Where a miniature arboretum is formed in a small garden, 

 this species may be considered valuable, as exemplifying the order /keracese, 

 in a space not larger than what would be required for a herbaceous plant. 



Statistics. The only specimens worth recording in Britain are those already referred to at Syon, 

 Chelsea, and Hendon. The plants in the London Horticultural Society's Garden, and at Messrs. 

 Loddiges's, are not above a foot and a.half high. In France, in the Jardin des Plantes, a tree 130 

 year* planted is 31 ft. high. In Saxony, at Worlitz, one 55 years planted is 40ft. high. 



Commercial Statistics. Plants, in the London nurseries, cost 5s. each ; at 

 Bollwyller, where it is considered as synonymous with A. heterophyllum, 

 2 francs each ; at New York, ?. 



App. i. Doubtful Species of A^cer. 



We have not been able to satisfy ourselves respecting the distinctness of A. 

 O'palus and A. opulifolium ; and we are very much inclined to think that the 

 sort which we have figured as A. barbatum is a European species, and, con- 

 sequently, not the A. barbatum of Michaux. To us, it appears that the A.
