1112 ARBORETUM ET FRUTICETUM BRITANNICUM. 



The following species will probably be very shortly introduced, and, indeed, 

 are perhaps already in a seedling state in the H. S. Garden : 



* M. lanceoldlum. (S. lanceolatum Benth. PI. Hart. p. 34. No. 269.) Pin- 



nate, with long slender leaves, and 13 17 leaflets, very spiny, and of a 

 dark green. Mexico, on mountains, where it grows from 5 ft. to 6 ft. 

 high. Considered the handsomest of all the Mexican species. (G. M. 



1840, p. 632.) 



* M. angustifolia. (B. angustifolia Hartw. Benth. Pi. Hart. No. 270.) Re- 



sembles M. fascicularis, but is much smaller in all its parts. Leaflets 

 5 7, light green, and very spiny. Mexico, where it grows from 6 ft. to 

 8 ft. high, with purple fruit, sweet to eat. 



* M. Hartwegii. (B. Hartwegw Benth. PI. Hart. No. 272.) Pinnate, with 



11 15 leaflets, which are nearly double the size of those of M. -dquifo- 

 lium, and of the same light green as those of that species. Mexico. 

 Flowering in April.

LIMO^NIA Laureola Wall. PI. As. Rar. t. 245., Royle Illust. vol. i. p. 343. 

 The only species of this order found on the tops of cold and lofty moun- 

 tains in the Himalayas, where it is for some months buried under snow. 

 Raised in the H. S. Garden from seeds received from Dr. Royle in 1841, 

 and probably hardy enough to endure our winters against a wall. (G. M. 



1841, p. 608.)

* HYPE'RICUM rosmarinifolium Lam. Diet. ; Tor. and Gray, vol. i. p. 159. A 



pretty narrow-leaved species, from Kentucky, where it grows 2 ft. high, 

 flowering in July and August. (G. M. 1842, p. 13.)

* ACER Icsmgdtum Wall. Plant. As. Rar. 2. p. 3. t. 104. ; Arb. Brit. 1st ed. 



p. 431. Leaves undivided, oblong, acuminate, smooth, and shining. 



Nepal, on high mountains, where it forms a tree 40ft. high. Dr. Wallich 



thinks it may prove hardy in England. H. S. (G. M. 1840, p. 632.) 

 A. colchicum Hartwiss. A very handsome and distinct plant, nearly allied 



to A. platanoides Lobelw; but with the lobes of the leaves more pointed, 



the bottom lobes lapping over the footstalk, their texture thinner, and 



their colour more glaucous than those of A. p. Lobelw. Abchasien ; 



whence it was imported by Booth of Hamburg in 1838, and introduced 



into England in 1840. (G. M. 1840, p. 632.) 

 *t A. colchicum var. rubrum Booth MS. From the beginning of the season 



till late in autumn the leaves are of a bright pinkish purple. The bark 



is brownish, while that of the species is of a pea-green, like the bark of 



Negundo /raxinifolia. 

 3 A. campestre. Add as Varieties : "A. c. rubris Booth : samaras red. A, 



c. heterocdrpum : samaras variously formed." 

 If A. gldbrum Torr. and Gr. Flor. 1 . p. 207. A shrub found in the Rocky 



Mountains, with leaves nearly similar to those of the common currant in 



size and shape. Not yet introduced. 

 3 A. tripartitum Nutt. Torr. and Gr. Flora, 1. p. 247. A shrub found on 



the Rocky Mountains, nearly allied to the preceding species, and, like it, 



not yet introduced. 



* A. grandidentdtum Nutt. Torr. and Gr. Flora, 1. p. 247. (? A. barbatum 



Doug/., not of Michx.) A shrub or low tree from the Rocky Mountains, 

 with leaves smaller than those of A. saccharinum. Not yet intro- 

 duced.
