FLORA AND SYLVA, 



Broom, Holly in berry, Mountain Ash brilliant in fruit, our native Barberry 

 (a lovely thing in fruit in groups), the Spindle Tree, and Viburnum, are among 

 our trees that give the most showy effect ; but for refined colour that of our 

 common woodland trees in picturesque planting is best of all. The colour 

 lacking in many districts, however, is that of the nobler Pines, with their fine 

 variety of perennial verdure from the Hemlock, Spruce, and Yew, that toss 

 their branches so finely in storms, to the silvery Californian trees and the 

 trees of noble stem-colour — Scotch Fir, Yew — and, indeed, nearly all Pines 

 in a mature state.

Tree Notes from Rochester (The Flower City). 



Among ornamental trees characterised by their showy 

 inflorescence, as well as by the beauty of their fruits 

 in autumn, none may surpass many of our native 

 Thorns ; and, perhaps, no region is as rich in the 

 variety of this genus as the immediate surroundings 

 of Rochester and the district of the famed Genesee 

 Valley, justly termed "The Garden of the Empire 

 State." In several recent visits to this section, the 

 eminent botanist, Dr. Charles S. Sargent, author of 

 " Silva of North America," discovered many new 

 species and varieties of the Crataegus, some of which 

 he has described in The Botanical Gazette of Febru- 

 ary 1902. Illustrations of some of the most distinct 

 types of these, when secured at a later date, may 

 prove of interest to the readers of Flora and Sylva. 



In recalling the Thorn, however, two other well- 

 known native flowering trees, the Shadblow and the 

 Dogwood, perhaps equally picturesque in their grace 

 of contour and drift of snowy bloom, should not be 

 lost sight of, whether imparting an added charm to 

 their natural habitat or supplying a vivid ornamental 

 adjunct to the home-grounds. Of these three graces 

 among native flowering trees of medium growth, the 

 Thorn or May-tree alone possesses in most of its 

 forms the added charm of pronounced fragrance. 

 The common English Hawthorn or quick, so largely 

 employed as a hedge-plant in Europe, does not 

 always weather the severity of our winters in some of 

 the northern states. It is, moreover, apt to become 

 sunburned, and suffers from mildew and the attacks 

 of the aphis. Many handsome specimen trees of the 

 double English Hawthorn, however, lend a lovely 

 note of colour to many of our gardens. 



In the list of comparatively new and little-known 

 trees may be mentioned a variety of the handsome 

 Sugar Maple, Acer sacc/ierinum, var. monumentalis, a 

 stately tree of pyramidal habit, very regular in its 

 growth, and distinguished for the brilliant crimson 

 colouring of the second-growth foliage. Another 

 comparatively new Maple is a purple-leaved form of 



the well-known Norway Maple, Acer platanoides,var. 

 Geneva, raised in the town of that name in this state. 

 This is a variety of robust growth, quite distinct from 

 Reitenbach's or Schwedler's, and that may be said to 

 combine the good qualities of each. Other trees of 

 recent introduction are the globe-headed Norway 

 Maple, with a perfectly rounded head, andThurlow's 

 Weeping Willow, a graceful pendulous tree with 

 leader of erect growth and drooping side branches. 



Among ornamental flowering trees and shrubs 

 which, though not unfamiliar, are not nearly as 

 well known abroad as they deserve to be, are Pyrus 

 angustifo/ia, or Bechtel's double-flowering American 

 Crab, perhaps the most interesting of the genus 

 when laden with its exquisite violet-scented, rose- 

 like flowers of delicate pink, in early spring. Still 

 more showy in its snow-white vernal garb is a form 

 of the favourite Japanese Deutzia, D. crenata^ var. 

 Pride of Rochester, a variety raised and dissemi- 

 nated by Ellwanger and Barry from D. crenata^fl.pl.^ 

 producing large double white blossoms, the back 

 of the petals being slightly suffused with rose. Ex- 

 celling all the other sorts in size of flowers, length 

 of panicle, profusion of bloom and vigorous habit, 

 it also blossoms nearly a week earlier than D. cre- 

 nata, fl. pi. 



A word of praise may likewise be added with 

 reference to a new native Elder, Sambucus canaden- 

 sis acutiloba, just introduced by the Mount Hope 

 Nurseries — a distinctly novel and highly orna- 

 mental shrub, surpassing S. keteropltylla, the well- 

 known fern-leaved variety. This will form a fine 

 companion for the cut-leaved Sumach ; and, with 

 its deeply and delicately cleft dark green foliage, it 

 will become valuable on account of its graceful 

 beauty, as well as its perfect hardiness, rapid growth, 

 and the ease with which it bears transplanting.
