FOKBST TREES, 181 



known Peruvian bark. First made known by the elder Michaux, 

 who found the trees growing on the St. Mary River in Florida in 

 1791, and carried seeds and plants to Charleston, S. C, and 

 planted them in his garden near that city, where they had 

 reached a hight of twenty-five feet in 1807, as stated by his son 

 in his great work. North American Sylvia, vol. I, p. 180. 



Pinckneja pnbens, Michx. — Georgia Bark.— Leaves large, oval 

 or oblong, smooth above, hoary pubescent underneath. Flowers 

 tubxilar, an inch and a half long, white, with broad stripes of 

 pink on the tube and in the center of the revolute petals. Fruit 

 a globose papery, two-celled, capsule, opening at the top and 

 containing numerous small seeds. A small tree with a wide 

 spreading top, seldom more than twenty-five feet high, or stem 

 over six inches in diameter. Wood very soft, and of no value, 

 but the bark has been used more or less as a substitute for 

 Peruvian bark, as it contained similar bitter tonic properties. 

 Found wild on the marshy banks of streams in South Carolina 

 and Florida. 



piRcrs, Linn. — Apple, Pear, Etc. 



An extensive genus, containing about forty species, princi- 

 pally in the temperate regions of Europe, Asia, and America. 

 The apple, pear, crab apple, quince, service tree, mountain ash, 

 and their many varieties, are all included in this genus. As 

 there are few trees among them worthy of the arboriculturist's 

 attention, I shall omit all except those inhabiting the United 

 States. 



Pirns Americana, DC. — American Mountain Ash. — Leaves com- 

 posed of thirteen to fifteen lanceolate, taper-pointed serrate 

 leaflets. Flowers white, in large, flat cymes or clusters. Fruit 

 in large clusters, not larger than peas, bright-scarlet, remaining 

 on the tree until winter. A handsome ornamental tree, twenty 

 to thirty feet high, reaching a very high northern latitude, even 

 being found in Greenland and Labrador, and throughout the 

 Canadas, all of our more Northern States, and southward along 

 the mountains to North CaroUna. There are several cultivated 

 varieties of this species, also a very large number of the Euro- 

 pean Mountain Ash (P. aucuparia), which may be found de- 

 scribed in nurserymen's catalogues. 



P. angastifolia, Ait. — Narrow-leaved Crab Apple. — Leaves lan- 

 ceolate or oblong, acute at the base, serrate. Flowers few in a 

 cluster, rose-color, very fragrant. Fruit very acid. A small
