both ends (the wings shaped like a common table-knife, but rather 

 broader in the centre) . 



In woods in several parts of Scotland ; in plantations in Eng- 

 land. Scarcely naturalized? Tree; flowers in May; fruit in Aug. 



A. campestre, Lin. Common or Field Maple. — e.b. 304. — A. 

 liebecarpum, DC. — l.b.s. 225. 



A. 10. C. 40. Lat. 50-55°. Alt. 0-200 yds. Tern. 52-47°. 



A tree which sometimes attains a great size, but is generally 

 only a hedge shrub. Leaves cordate at the base, with 3-5 un- 

 equal hlunt lobes ; the middle and lateral lobes are subdivided into 

 three obtuse segments. Flowers green, in corymbose clusters, 

 erect, sessile. Fruit turgid, convex on both sides, with divergent 

 horizontal wings, which are of a more uniform width than in A. 

 Pseudo-platanus. 



Common in hedges in England. Shrub ; flowers in May and 

 June ; fruit, July and August. — In Scotland we saw a very lofty 

 tree of this Maple. See ' Phytologist' for October, 1856. 



At Blairlogie, in Stirlingshire, there is a tree of this species 

 fifty-five feet high and four feet in diameter, and the circumfe- 

 rence of the head about fifty yards. Its age is estimated at up- 

 wards of three hundred years. This far exceeds the INIaple which 

 we saw near Callander, in Perthshire. See ' Phytologist,' as above. 

 The soil and climate of Scotland appear to be congenial to trees 

 of this kind. The examples are very numerous, and the dimen- 

 sions are often very great. See Loudon's ' Arboretum,' pp. 416- 

 430. 



LINACE^, DC. The Flax Family. 



Annual or perennial herbaceous plants, often half-shrubby at 

 the base. Leaves entire, scattered. Flowers regular, terminal 

 or lateral, in forked cymes or in clusters by abortion. Sepals 

 5, rarely 4, free, rarely connected at the base, persistent, im- 

 bricate in prefloration. Petals 5, rarely 4, caducous, twisted in 

 prefloration. Stamens 4-5, slightly united by the base of their 

 filaments, often with the rudiments of an inner row^ opposite to 

 the petals. Anthers 2-lobed, introrse. Ovary free, consisting 

 of 5, rarely of 3-4 carpels, and with as many cells as carpels, 

 containing two ovules in each ; each cell is separated by an im- 

 perfect partition, and forms two imperfect, one-seeded cells. 

 Ovules attached to the inner angles, suspended. Styles 5, rarely
