BRITISH FLORA 



are pink, the stamens long. The fruit is scarlet. 

 The plant is tall, flowering in May and June, and 

 is a deciduous tier. 



Pyrus scandica, E. & H., non Aschers. This 

 species is only found in two vice-counties. Mr. 

 Druce in his Oxford list unites P. scandica, As- 

 chers, with P. intermedia, Ehrh. The late Rev. 

 A. Ley regards the Arran plant with broader 

 leaves and larger fruit, from the west of England, 

 as distinct from the Arran plant (P. scandica, 

 Syme, Sorbus scandica, Fries) and P. scandica, 

 Aschers. This name is retained in the last loth 

 edition (1908) of the London Catalogue. The P. 

 scandica, E. & H., Mr. Druce places as a variety 

 of P. intermedia, Ehrh. It differs from the latter 

 as defined by Mr. Druce in the leaves being less 

 narrowed, almost rounded at the base, deeply 

 lobed, with numerous sharp teeth, and 6-8 pairs 

 of leaves. The fruit is large. 



Pyrus semipinnata, Roth. This plant is found 

 in seven vice-counties, but is as a whole doubtful. 

 The plant resembles P. fennica, Bab. = P. pinna- 

 tifida, Ehrh., having oblong, lance-shaped leaves, 

 bluntly lobed, pinnate below. The habitat is 

 shrubberies. 



Pyrus cordata, Desv. = Briggsii, Syme. The 

 habitat of this plant is woods and hedges. The 

 plant has the tree habit. The leaves are heart- 

 shaped, egg-shaped, with a round base, nearly 

 hairless. The flowers are white. The fruit is 

 very small, pear-shaped or rounded. The plant 

 is 10-22 ft. in height, and flowers from April to 

 June, being a small deciduous tree. 



Wild Pear (Pyrus communis, L.). The habitat 

 of this plant is woods, thickets, and hedges. It 

 has the tree habit. The branches bear spines, 

 and are pendulous. The leaves are in groups on 

 the last year's wood. They are alternate, elliptic, 

 oblong, egg-shaped, toothed, sometimes inversely 

 egg-shaped, and narrowed to an acute point, 

 downy below, and lobed when young, then smooth. 

 The leaf-stalk is slender. The flowers are white, 

 in a simple cyme or corymb, the style is distinct, 

 the ovary woolly, the fruit long, pear-shaped, the 

 base inversely conical. The plant is 20-40 ft. in 

 height, flowering from April to May, and is a 

 deciduous shrub or small tree. 



Wild Service (Pyrtts tortninalis, Ehrh.). The 

 habitat of this plant is woods, hedges, in the south 

 especially. The Wild Service has the tree habit. 

 The branches and young leaves are downy below. 

 The leaves are egg-shaped, heart-shaped, oblong, 

 6-io-lobed, smooth, the lobes triangular, toothed, 

 the lower lobes larger and spreading, with a long 

 narrow point. The numerous flowers in compound 

 corymbose cymes are white. There are two car- 

 pels. The fruit is oval, pear-shaped or nearly 

 round, and greenish-brown, 2-ceIled, spotted or 

 dotted, acid. The plant is a small tree, 10-30 ft., 

 flowering in April and May, and is a deciduous 

 tree, attaining a large girth when full-grown. 



Medlar (Pyrtts germanica, Hook., fil.). The 

 habitat of this plant is thickets and hedges. The 

 Medlar has the tree habit. The stem is much- 

 branched, bearing spines when wild. The leaves 



are lance-shaped, simple, entire, downy below, 

 inversely egg-shaped or oblong, rarely simply 

 or doubly toothed. The flowers are white, on 

 short flower-stalks, solitary. The calyx is downy, 

 the persistent lobes having enlarged, leafy tips. 

 There are 5 styles. The fruit is rounded, large, 

 with a bony endocarp, 5-celled, the cells seeded, 

 with a large flattened area at the top. The plant 

 is a fairly tall tree, flowering in May and June, 

 and is deciduous. 



ORDER RIBESIACE^ 



Gooseberry (Ribes Grossularia, L.). The habi- 

 tat of this plant is copses. The habit is of the 

 bush or shrub type. The plant is spreading, the 

 stem and branches prickly, with 1-3 thorns at tin-

 in the bud. They are rounded, 3~5-lobed, the 

 margin cut, scalloped, smooth or hairy, grouped 

 on short, lateral branches. The flowers are 

 green, drooping, the flower-stalk short, downy,

 male flowers in a dense raceme, 20-30 flowers, 

 the female short, 8-10, the flowers yellow, the 

 female greener. The bracts are linear, and longer 

 than the flower-stalks, lance-shaped. The petals 

 are shorter than the sepals, the calyx smooth, and 

 the limb flat. The berry is round, scarlet, insipid. 

 The styles are short and cleft. The plant is 2-4
