1502 ARBORETUM AND FRUTICETUM. PART II J. 



Mocca-stone moth (Smith \ 299 



and Abbott's Insects, t. 

 72. ; and our fig. 1299.) 

 The caterpillars of this 

 insect appear all collected ^ 

 together in a web spun J 

 among the leaves. The 

 larva is of a bright yel- 

 low, streaked with brown, 

 and the imago of a pale 

 brown. The insect is 

 equally common in Eu- 

 rope and in America. 

 There are plants in the 

 Twickenham Botanic 

 Garden, and the Hackney 

 arboretum ; and at Wo- 

 burn, Henfield, and Flitwick.

London Horticultural Society's arboretum. 

 Engravings. Sal. Wob., No. 17. ; and fig. 17. in p. 1606. 



Spec. Char., fyc. Leaves elliptical, rounded at the base, pointed at the tip, 

 serrated, whitely glaucous beneath. Catkins appearing with the leaves. 

 Flowers triandrous. Ovary pedicellated, ovate, smooth. Stigmas sessile. 

 ( Willd. and Forbes.) A native of Dauphine, where, according to Willdenow, 

 it forms a shrub 5 ft. or 6 ft. high, with dark violet-coloured, shining branches; 

 but, according to the experience of Mr. Forbes, in the Woburn salictum, 

 it is a handsome upright-growing tree, attaining the height of 12ft. or 

 14 ft., with the preceding year's branches of a greyish brown colour, and 

 the young twigs dark brown above, paler beneath, polished, and some- 

 what angular, or striated, and very brittle. Introduced in 1818. The 

 male, as observed in the London Horticultural Society's arboretum, in 

 1835, is an elegant kind, noticeable early in spring for its plentiful blos- 

 soms, and subsequently for its leaves, which are remarkably neat in their 

 figure and serrature, and more or less peculiar as compared with those of 

 kindred kinds. The dark colour of the shoots of the preceding year or 

 years is also an ornamental feature. There are plants at Woburn Abbey, 

 Henfield, and Flitwick House. 



App. i. Triandrce of which there are Plants in the Country not 



described. 



S. tenuifolia Lodd. Cat, ed. 1836, and S. tenuifblia G., in the collection at Hackney, appear to be 

 the same, and near akin to S. lanceolatum ; but are very different from the S. tenuifolia of Smith. 



App. ii. Triandrtf described, but not yet introduced^ or of doubt- 

 ful Identity with Species in the Country.
