ICOSAND. PENTAG. 151 



HAB.|Hcclges about the Abbey of Melrose, Light/. Pentland Hills, 

 Mr. G. Don. Fl. May. fj . 



Small tree, having black globular /r«j^ with a blue bloom. 



5. Pr. sphiosa {Black-.'horn or Sloe-tree), peduncles (mostly), 

 solitary, leaves elliptico-lanceolate subpubescent beneath, 

 branches very spin ose. Light/, p. 254. E. B. t,SA2. 



Hab. Hedges, frequent, Fl. Apr. May. Tj . 



It is difficult, in a fev/ words, to distinguish this well-known shrub 

 from the last. It is much smaller in all its parts, and the branches 

 are more crooked and spinose. In the former, the leaves are rather 

 considerably advanced at the time of the blossoms appearing : in 

 this the flowers are generally past before the leaves appear. Fruit 

 small, very austere. Used to adulterate Port wine, as the leaves 

 are to mix with tea. 



2. PENTAGYNIA. 



2. CRAT^GUS. 



1. C. Oxyacantha {Hawthorn or Whitethorn), spiny, leaves 

 glabrous cleft into three or five deep serrated segments the 

 lower ones spreading, flowers corymbose, styles 1 — 2. Lightf, 

 p. 255. E. B. t. 2504. 



Hab. Woods and hedges, almost every where. Fl. June. Tj . 



Variable in the form of the leaves and size and colour of the petals, 

 which are often tinged with rose colour. The cal. too is more or 

 less downy and acute. Few of our native plants can present a 

 more beautiful sight than a well-grown bush of Hawthorn, with its 

 dense masses of white flowers backed by the shining dark green 

 leaves. Nor is it less desirable on account of its scent ; though 

 there are many indivi lual plants perfectly destitute of it. It is ex- 

 cellent for fences, and bears clip])ing admirably. The fruit (or 

 haws) afibrds a supply of food to innumerable birds in a season 

 when scarcely any thing else is to be obtained. — The C. monogyna 

 of Jacquin is but a var. of this. 



3. PYRUS. 



1. P. Malus {Cral- Apple), leaves ovate acute serrated, flowers 

 in a sessile umbel. Lightf. 258. E. B. t, 179. 



Hab. Woods and hedges. Frequent about Glasg., Hopk._ Fl. May. T2 . 

 A good sized tree, the origin of our numerous varieties of garden 



Apple. Flowers large, tinged with rose colour on the outside. 



Fruit austere, of which Verjuice is made. 



2. P. aucuparia {Mountain Ash ox Roan-tree), \ea.yes pinnated 

 glabrous on both sides, flowers corymbose. Light/, p. 256 

 {Sorhus aucuparia). E. B.t. 337. 



Hab. Woods 5 abundant both in the Highlands and Lowlands. Fl. 

 May, June. Pj . 



A small handsome tree. Leaflets elliptico-lanceolate, serrated, entire 

 at the base. Floivers small but numerous. Fruit red. The wood 

 is much used and valued for its compactness, and the tree itself is 

 possessed of many virtues, according to the superstitious notion ; 

 of the Highlanders.
