 our fig. 210. ; and the plate of this tree in Vol. II. 



Spec. Char., S,-c. Leaves elliptical, acuminate, quite 

 entire, lineatcd with 12 or 15 lateral nerves ; younger 

 leaves and calyxes villous. Flowers hermaphrodite. 

 (Don's Mil/., 'ii. p. 32.) A deciduous shrub, with 

 the habit of a low tree ; a native of the Azores, on 

 the mountains of St. Michael. Introduced in 1778. 

 It Mowers in July, and the berries which succeed 

 them are either red or black, both colours appearing 

 on the same plant. The leaves are larger than those 

 of any other species; and the whole plant is remark- 

 able for its robust appearance, and the conspicuous 

 opposite nerves, which proceed from the middle of 

 the leaves. It deserves a place in every collection. 

 There is a tree of it at Syon 15 ft. high. In London, 

 plants are from 1*. to 1*. 6d. each. At Bollwyller, 

 1 franc and 50 cents ; and at New York, 50 cents.

R. amygdalinus Desf. Atl., 1. p. 198., a native of the north 

 of Africa, in the fissures of rocks, where it grows to the height 

 of 3 ft., and produces berries used for dyeing yellow, like those 

 of R. saxatilis. 



R. y>ersicifblius Moris. Stirp. Sard, 4to, fasc. 2., a native of Sar- 

 dinia, and probably only a synonyme of R. amygdalinus. 



R. prunifblius Smith Prod. Fl. Graec, 1. p. 157., a native of 

 Crete, on the highest mountains, and probably only a variety 

 of one of the preceding 

 sorts. 2 1 2

 Frangula.

 a the R. alnif olius of Pursh 

 V$^W* ill lii ill 1 ! but not of L'Heritier, a 



shrub, growing to the 

 height of 6 ft., native of 

 North America, on the 

 banks of the Koorkoosky. 

 R. sanguineus Pers., a native of Galicia, on the banks of rivers, where it grows to the height 

 of 6 ft. 



R. minutiflbrus Pursh, a native of the sea coasts of Carolina and Florida. 



The following species probably belongs to another genus ; but, not having seen the plantVe can 

 say nothing about it of our own knowledge. 



R.carpinifblius Pall. Ross., 2. p. 24. t. 60., Willd. Spec, 1101., and N. Du Ham., vol. iii. p. 40., 

 (fig. 212.) is said to be a tree resembling the hornbeam. Pallas says that it abounds in the calcareous 

 mountains of Kutais, in Russia, but that he never saw its flowers. It may possibly be a Planenz.

 ]'•--, half-hardy.

BbOl « , there are some doubtful green-house species, all of which it would be desirable 

 to procure, la order to prove their degree of hardiness, and assist in reducing this genus to order.
