PREFACE So much has been written popularly and in a scientifie way on trees that no book on the subject would be warranted unless it was designed to meet a decided need. At present there is no general work upon American trees which combines illustrations of the individual forms with keys for their identification based upon winter characters. The forester and lumberman, however, are more called upon to distinguish trees in winter when leaves and flowers are fallen than in summer. Trees, as the most con- spicuous elements in the winter landscape, must also appeal to the student of out door life. The interest shown by classes of school teachers in the Summer School in identifying specimens of twigs collected the previous winter indicated that the winter study of trees can be taken up with enthusiasm by teachers in their schools. In our experience, the winter identification of trees has proven to students one of the most interesting subjects of their course. It is of decided value for its training in the power of accurate obser- vation. The work comes at a time when material for natural history study seems scanty and might therefore be used to bridge over the period between fall and spring which are unfortunately considered by many the only seasons when study of out door hfe is possible in the schools. A tree in winter is far from being the characterless object many believe. Freed from its covering of leaves, the skeleton of the tree is revealed and with the method of branching thus clearly discernible, the species may generally be more readily identified at a distance than in its summer garb. There are many forms, moreover, that are difficult to distinguish from suminer features alone but which in winter have twig, bud or other characters which make their separation comparatively easy. It is believed that the combination of keys, text, and illus- trations from photographs will furnish the assistance which the current texts fail to supply and render the identification of our common trees in winter a relatively simple task. The text with keys is an outgrowth of outlines that one of the authors has developed and used with various modifications for the last four years in his college classes in Botany and Forestry. 308 NEW ENGLAND TREES IN WINTER. The photographie illustrations are all originals, most of them by the other author. Although one of us is responsible for the text and for the selection of the material photographed and the other for the photographs, we have freely consulted and the bulletin is therefore to be considered a joint publication. The order of arrangement of the species in the text and the scientific names follow the-usage of the seventh edition of Gray’s Manual and the latter are in accord with the rules laid down in the Vienna Congress. The figures and descriptions given are of trees for the most part growing wild in New England. A few rarer species which occur in New England only very locally or in isolated instances have been omitted from illustration. In their places, however, some of the more frequently cultivated trees, have been included because of their value for forestry planting in New England or beeause of their familiarity in city ornamental plant- ings. The varieties of cultivated forms are so numerous that it is obviously possible to take account of only the most common types. Their inclusion, it is believed, will add to the value of the publi- cation especially for its use in cities. The keys can be absolutely relied upon only for the species just mentioned from New England. New England, including as it does the meeting ground between the northern and southern floras, is extremely rich in the species of trees represented. The bulletin, therefore, especially in its descriptive text and illustrations should prove of service outside of the geographically restricted region described. The final keys to the genera and to the species as well as the descriptive text in galley were placed in the hands of the present s in Botany and Forestry. A student after finding year’s cla the species by the keys, read the twig characters in the galley and signed his name opposite the species if the description corres- ponded with the twigs supplied. All of the trees described and illustrated have thus been checked up hy students and some of them by as many as seventy different persons. In this way limitations to the use of certain of the characters employed as means of separating allied species have been discovered and the constancy of other characters has been confirmed in so far as the material available could allow. The greatest assistance rendered by the students, however, has heen in disclosing difficulties in the use of the keys, due to unfortunate choice of contrasted characters or of STORRS AGRICULTURAL EXPERIMENT STATION. 309 terms used in their description. The keys in conse- quence have been considerably modified before final paging. Many of the explanatory phrases which may appear to be unnecessary have been inserted at the demand of the students. Where possible the most obvious characters have been employed and though the keys in consequence have become somewhat more cumbersome it is hoped they will prove more usable. Errors and omissions have no doubt crept in despite the efforts to avoid them. We would be grateful for any additions or corrections that may be suggested in the descriptions or keys in view of a possible revision of the text. The photographs of the twigs and of the fruit of the deciduous trees are very nearly natural size. They have been slightly reduced in production but all of them to the same scale, except the fruits of the Catalpa, the Chestnut, and the Honey Locust as indicated under these species. Line drawings or touched- up photographs would no doubt show important details more clearly by emphasizing certain of the minute markings. Since, however, these details are often obscure, and moreover receive full recognition in the accompanying text, it has been thought that a truer idea of the twigs would be gained if they were left as they appeared in the photographs. Accordingly, they have not been “doctored” in preparation or reproduction. The leafy twigs of the cone-hearing evergreens have been more or less reduced as indicated under the descriptions of the genera in the key. All the twigs of a single genus, however, are on the same scale. LITERATURE The following is a list of books which will be found useful to the student of New England trees. They have been freely consulted, as well as others not listed, and have been of value in determining the ranges and wood characteristics of the indi- vidual species, in confirmation of bark and habit characters, and to a less degree of the other winter features. The dimensions of the trees in the heading “Habit” and the information under the heading “Distribution” have been taken with little change from Dame & Brooks’ Handbook, except what is given in the subhead- ing “In Connecticut” which was obtained from the catalog of the flowering plants and ferns of Connecticut; Bulletin No. 14, 310 NEW ENGLAND TREES IN WINTER. Conn. Geol. and Nat. Hist. Survey, 1910. The characters under the heading “Wood” were taken chiefly from Sargent’s Manual. To obtain information in regard to the dimensions, the distribution and the wood characters of cultivated species, Bailey’s Cyclopedia of Horticulture and various European works have been freely consulted.

ALBERT FRANCIS BLAKESLEE. CHESTER DEACON JARVIS. Storrs, Conn., June, 1911. STORRS AGRICULTURAL EXPERIMENT STATION. 313 INTRODUCTION Before considering the individual trees in detail it seems de- sirable to give a general discussion of the different terms used as headings in the description of the species. NAME tree and this name is used throughout the book as the designation A common English name heads the description of each of a particular species. The same form may be known in different localities by several entirely different common names. Thus the Tupelo in some places is called only Pepperidge, in others, Sour Gum or Black Gum. After consultation with the literature the name Tupelo was chosen as being somewhat more desirable for the whole of New England than the other names given in smaller type as synonyms. Often several common names may be in about equally frequent use. There is, however, only one scientific name at present sanctioned by botanical authorities and this is placed first, followed by the Latin synonyms in italics. THABIT—By the word habit, we denote the general appearance of a tree seen as a whole.

HABIT—The tallest conifer of New England, 50-80 ft. high with a trunk diameter of 2-4 ft., in virgin forests of northern New England trees have been found over 150 ft. in height with a trunk diameter of 7 ft.; trunk straight, tapering gradually, normally continuous into the crown, with wide-spreading, horizontal limbs, in young trees generally arising in whorls of five, and with secondary branches in the same plane, producing characteristic horizontal layers; head broadly conical, spray delicate, bluish-green. BARK—On young trunks and branches, smooth, greenish-brown, becoming fissured into comparatively shallow, broad, flat-topped, longi- tudinal ridges. i ; ; TW1GS—Slender, light brown smooth or slightly hairy, resinous. LEAVES—In clusters of 5, without sheaths in winter, soft, bluish- green, flexible, 3-5 inches long, slender, 3-sided. MICROSCOPIC SECTION—showing a single fibro-vascular bundle, 1 or 2 peri- pheral resin-ducts, a single lay er of strengthening cells only beneath the epidermis, stomata only on the two inner sides. BUDS—Ovate to oblong, about 1 cm. long, sharp-pointed, bud-scales long, pointed, yellowish-brown. FRUIT—Cones, 4-10 inches long, stalked, drooping, cylindrical and more or less curved. SCALES—thin, not thickened at apex and without spines. Seeds winged. COMPARISONS—The White Pine is the only Pine of New England that has 5 needles in a cluster. The layered arrangement of its secondary branches enables it to be recognized as far as it can be seen. Young trees can be further distinguished from the Pitch or Red Pines by the greater delicacy and bluer color of the leafage. Frequently the terminal bud of the central leader is killed by an insect, the Pine Weevil, thus interrupting the growth and causing one or more of the young lateral branches to grow erect to take its place. Gnarled old specimens which have many times in their lifetime suffered these insect injuries may present a rather picturesque appearance but are of little value for lumber. The tree photographed perhaps had its leader killed when young but despite the three erect limbs which have taken the place of the single leader it still shows the outline characteristic of the species. DISTRIBUTION—In fertile soils; moist woodlands or dry uplands; often planted for ornament, wind-breaks and for reforestation. New- foundland and Nova Scotia, through Quebee and Ontario to Lake Winnipeg; south along the mountains to Georgia, ascending to 2,500 feet in the Adirondacks and to 4,300 feet in North Carolina; west to Minnesota and Iowa. IN NEW ENGLAND—Common, from the vicinity of the sea coast to altitudes of 2,500 feet, forming extensive forests. IN CONNECTICUT—Occasional near the coast becoming frequent northward and common in northeastern Connecticut. WoOoOD—Light, not strong, straight-grained, easily worked, light brown often slightly tinged with red, largely manufactured into lumber, shingles and lathes, used in construction, for cabinet- making, the in- ee finish of buildings, woodenware, matches and the masts of ves- sels. WHITE PINE 346 NEW ENGLAND TREES IN WINTER. PITCH PINE Hard Pine, Yellow Pine. Pinus rigida Mill. HABIT—Generally a low tree 30-50 ft. in height with a trunk diameter of 1-2 ft. occasionally 70-80 ft. in height with trunk diameter of 2-4 ft.; trunk more or less tapering, branches thick, gnarled, often drooping, forming an open pyramidal or oblong head; foliage in coarse rigid, yellowish-green tufts. Dead branches and old persistent cones are frequent and the tree has generally a decidedly scraggly appearance. BARK—On young trunks and branches rough, broken into reddish brown scales, with age becoming deeply furrowed into broad _ flat- topped ridges separating on the surface into rather loose dark reddish- brown scales. Clusters of leaves and short branches are not infre- quently formed directly from the old trunk (see in photograph above the tape measure.) TW1GS—Stout, light brown, not downy, roughened especially after the fall of the leaves by the decurrent bases of scales subtending the leaf- clusters. LEAVES—In clusters of 3, with persistent sheaths, yellowish- green, 2-5 inches long, stout, stiff, spreading, with pointed tips. MICROSCOPIC SECTION ided, showing 2 fibro-vascular bundles, resin-ducts located intermediate between bundles and_ periphery, strengthening cells beneath the epidermis in patches several layers thick, generally surrounding the resin-ducts and at one side of the vascular bundles, stomata on all three sides. BUDS—Cylindrical to ovate, pointed, resin-coated, scales reddish- brown. FRUIT—Cones 115-4 inches long, without stalks, ovate becoming more or less spherical when opened, borne laterally, singly or in clusters at about a right angle to the twig, often remaining on the branches for ten or a dozen years and frequently found on trees only a few feet high. SCALES—thickened at tip and with a stiff recurved prickle. COMPARISONS—The Pitch Pine is the only native Pine in New England that has three needles in a cluster. Its ragged appearance with frequent dead branches, persistent cones, and yellowish-green stiff foliage renders it easily distinguished from the White and Red Pines without examination of the needles. DISTRIBUTION—Most common in dry, sterile soils, occasional in swamps. New Brunswick to Lake Ontario; south to Virginia and along the mountains to northern Georgia; west to western New York, Ohio, Kentucky, and Tennessee. IN NEW ENGLAND—Maine—mostly in the southwestern section near the seacoast; as far north as Chesterville, Franklin county; scarcely more than a shrub near its northern limits: New Hampshire—most common along the Merrimac valley to the White Mountains and up the Connecticut valley to the mouth of the Passumpsic, reaching an altitude of 1,000 feet above the sea level; Vermont—common in the northern Champlain valley, less frequent in the Connecticut valley; common in the other New England states, often forming large tracts of woodland, sometimes exclusively occupying extensive areas. ue Sone oe Rare or local in Litchfield county, frequent else- Pnenre. _WwooD—Light, soft, not strong, brittle, coarse-grained, very durable, light brown or red, with thick yellow or often white sapwood; largely used for fuel and in the manufacture of charcoal; occasionally sawed into lurnber, PitcH PINE 348 NEW ENGLAND TREES IN WINTER. JACK PINE Northern Scrub Pine, Gray Pine, Spruce Pine. Pinus Banksiana Lamb. P. divaricata auth. HABIT—Usually a low tree 15-30 ft. in height with a trunk diameter of 6-S inches, under favorable conditions becoming 50-60 ft. high with a trunk diameter of 10-15 inches; with large spreading branches forming an open symmetrical head sembling somewhat the Spruce in regular- ity of outline or on exposed windy situations and in poor soil becoming stunted with gnarled stem and irregular scraggly distorted head. BARK—Dark reddish-brown with irregular rounded ridges roughened with close scales. s—Rather slender, reddish to purplish brown, not downy, rough- ales subtending leaf-clusters. TWIG ened by LEAVES—In clusters of 2, with short persistent sheaths, dark yellowish-green, %-1% inches long, stout, stiff, generally curved and twisted, flattened or concave on one side, rounded on the other, tip pointed. MICROSCOPIC SECTION—showing 2 widely separated fibro-vascular bundles, resin-ducts located intermediate between bundles and periphery, a single layer of strengthening cells around the resin- ducts and one or more layers beneath the epidermis. BUDS—Ovate, short-pointed, coated more or less thickly with resin. FRUIT—Cones 1-2 inches long, without stalks, conic-oblong usually curved and pointing forward, appearing between or sometimes at the whorls of lateral branches, more or less distorted. remaining closed for several years, persisting on the tree often for a dozen years. SCALES—in young cones with an incurved prickle, when mature thickened at the apex without spines or prickles. COMPARISONS—The short yellowish-green needles of the Jack Pine will distinguish this species from other Pines. The longest needles some- times approach in size short needles of the Scotch Pine, but those of the Seotch Pine are of a bluish-gre2n color and moreover their cones point backward instead of forward as in the Jack Pine. DISTRIBUTION—Sterile, sandy soil; lowlands, boggy plains, rocky slopes. Nova Scotia, northwesterly to the Athabasca river, and north- erly down the Mackenzie to the Arctic circle; west through northern New York, northern Illinois, and Michigan to Minnesota. IN NEW ENGLAND—Maine—Traveller Mountain and Grand Lake; Beal's Island on Washington county coast, Harrington, Orland, and Cape Rosier; Schoodic peninsula in Gouldsboro, a forest 30 ft. high; Flagstaff; east branch of Penobscot; the Forks; Lake Umbagog; New Hampshire—around the shores of Lake Umbagog, on points extending into the lake, rare; Welch mountains; Vermont—rare, but few trees at each station; Monkton in Addison county; Fairfax, Franklin county; Starkesboro. IN CONNECTICUT—Not reported. WoOD—Light, soft, not strong, close-grained, clear pale brown or rarely orange color with a thick nearly white sapwood; used for fuel and occasionally for railroad ties and posts; occasionally manufactured into lumber. i Jack PINE 390 NEW ENGLAND TREES IN WINTER. RED PINE Norway Pine. Pinus resinosa Ait. HABIT—A tree 50-75 ft. in height with a trunk diameter of 2-3 ft., in Maine, reaching a height of over 100 ft.; trunk erect, continuous into the crown with stout spreading branches often dependent and ascending at their tips, more distinctly whorled than in the Pitch Pine, in young trees clothing the trunk to the ground, forming a broadly pyramidal head becoming irregularly round-topped with age. Foliage in long flexible dark green tufts. BARK—Reddish-brown, with shallow flat ridges, separating off in irregular thin tlaky scales. TWI1GS—Stout, light reddish brown, not downy, roughened by decur- rent scales subtending leaf clusters especially toward base of each year’s growth. LEAVES—In clusters of 2, with long persistent sheaths, dark green, shining, 3-6 inches long, slender, soft, flexible, flattened on one side, rounded on the other, with pointed tip. MICROSCOPIC SECTION —showing 2 fibro-vascular bundles, peripheral resin-ducts, a single layer of strengthening cells beneath the epidermis and around the resin-ducts, stomata all around. BUDS—Oblong to conical, pointed; scales reddish-brown. FRUIT—Cones about 2 inches long, without stalks, ovate-conical, when opened more or less spherical, making a right angle with the stem, ripened cones remaining on the tree during winter. SCALES—thickened at apex but without spines or prickers. COMPARISONS—The Red Pine with two long needles in a cluster is not to be confused with our native New England Pin It resembles however, the Austrian Pine, but may be distinguished from this species by its more slender flexible needles (see under Austrian Pine). DISTRIBUTION—In poor soils; sandy plains, dry woods. Newfound- land and New Brunswick, throughout Quebee and Ontario, to the southern end of Lake Winnipeg; south to Pennsylvania; west through Michigan and Wisconsin to Minnesota. IN NEW ENGLAND—Maine—common,. plains, Brunswick, (Cum- berland county); woods, Bristol (Lincoln county); from Amherst (western part of Hancock county) and Clifton (southeastern part of Penobscot county) northward just east of the Penobscot river the predominant tree, generally on dry ridges and eskers, but in Green- bush, and Passadunkeag growing abundantly on peat bogs with Black Spruce: hillsides and lower mountains about Moosehead, scattered: New Hampshire—ranges with the Pitch Pine as far north as the White Mountains, but is less common, usually in groves of a few to several hundred acres in extent; Vermont—less common than the White or the Pitch Pine, but not rare; Massachusetts—still more local, in sta- tions ee separated, single trees or small groups; Rhode Island—occa- sional. IN CONNECTICUT Rare or local; Granby, Salisbury. woopd—Light, hard, very close-grained, pale red, with thin yellow often nearly white sapwood; largely used in the construction of bridges and buildings, for piles, masts and spars. The bark is occasionally used for tanning leather. Rep PINE 352 NEW ENGLAND TREES IN WINTER. AUSTRIAN PINE Black Pine. Pinus Laricio, var. austriaca Endl. HABIT—A tall tree reaching 60-80 ft. in height; trunk erect contin- uous into the crown, branches in young trees regularly whorled, foliage in rigid dark green tufts. BARK—Grayish-brown, roughened with scaly ridges, reddish-brown within. TWIGS—Stout, yellowish-brown, not downy, roughened by decurrent scales subtending leaf-clusters especially toward base of each year's growth. LEAVES—In clusters of 2, with relatively short persistent sheaths, dark dullish green, 3-5 inches long, rigid, flattened on one side, rounded on the = other, sharp-pointed. MICROSCOPIC SECTION—showing 2 fibro-vascular bundles, resin-ducts located intermediate between bundles and periphery, strengthening cells beneath the epidermis in patches several layers thick also surrounding the resin-ducts and on one side of the fibro-vascular bundles, stomata all around. BUDS—Oblong-conical, pointed, sometimes covered with a white resin. FRUIT—Cones 2144-3 inches long, without stalks, ovate-conical, becom- ing broadly ovate when opened, making about a right angle with the stem. SCALES—thickened at apex, generally with a short dull spine. COMPARISONS—The Austrian Pine resembles most closely the Red Pine among our New England species. The stiff character of its sharp-pointed leaves in distinction to the soft flexible leaves of the Red Pine may be observed by striking the open hand against a tuft of the needles. The winter twigs of the Austrian Pine are yellowish- brown, those of the Red Pine are bright red. The microscopic sections of the leaves of the two species are very distinct. DISTRIBUTION—A native of Europe but frequently cultivated in this country as an ornamental tree and to some extent used in forest planting. WwooD—Light, soft, rich in turpentine and very durable. In Europe the wood is used as a building timber and turpentine is obtained from the tree. AUSTRIAN PINE 354 NEW ENGLAND TREES IN WINTER. SCOTCH PINE Scotch “Fir.” Pinus sylvestris L. HABIT—A tree up to 70 ft. or occasionally 120 ft. in height; as cultivated in this country in the open, often a low branching tree with more or less pendant limbs and inclined trunk presenting a rather straggling unkempt appearance; frequently of more erect habit, espe- cially in company with other trees. BARK—Grayish-brown, scaly, upper part of trunk and_ branches characteristically smoothish in appearance by flaking off of the outer bark in thin papery light-reddish layered scales. TWIGS—Of medium thickness, dull grayish-yellow, not downy, rough- ened by scales subtending leaf clusters. LEAVES—In clusters of 2, persistent, sheaths becoming lacerated, dull bluish-green 114-315 inches long, stiff. generally twisted, flat or concave on one side, rounded on the other, pointed. MICROSCOPIC SECTION—showing 2 fibro-vascular bundles, peripheral resin-ducts, strengthening cells around resin-ducts, at one side of the bundles and beneath the epidermis, stomata all around. BUDS—Oblong-conical, brown, often somewhat resinous-coated. FRUIT—Cones 1%-2% inches long, short-stalked, grayish or reddish brown, conic-oblong, generally appearing with the whorls of lateral branches, usually pointing backward. SCALES—in young cones with a short projection which when mature may persist as a short weak incon- spicuous point or is deciduous, apex of scale thickened with a more or less prominent four-sided boss often recurved especially toward base of cone. COMPARISONS—The Scotch Pine often improperly called Scotch “Fir” may be distinguished from the other Pines native or cultivated in New England by the bald reddish appearance of the upper part of trunk and branches, the short bluish-green leaves and the backward-pointing cones. DISTRIBUTION—A European tree cultivated abroad in extensive for- ests for its timber. In this country more or less planted as an orna- mental tree, and sparingly escaped from cultivation. In Connecticut rare or local as an escape; New London, Lyme, Southington, Bridgeport. WooD—Light, soft, reddish-brown with thick light yellowish or red- dish sapwood, easily split and durable, corresponding in importance abroad to the White Pine in this country. ScotcH PINE 306 NEW ENGLAND TREES IN WINTER. AMERICAN LARCH Tamarack, Hackmatack, Black Larch, “Juniper.” Larix laricina (Du Roi) Koch. L. americana Michx. HABIT—A tree 30-70 ft. in height, with a trunk diameter of 1-8 ft., at high altitudes reduced to 1-2 ft. in height; trunk erect continuous into the crown, branches irregular or indistinctly whorled, in young age and when crowded and in swamps forming a narrow symmetrical pyramidal head, in old age becoming broader and of irregular form. The Larch is the only New England cone-bearing tree that sheds its leaves in the fall; specimens in winter consequently are frequently mistaken for dead trees. BARK—On young trunks smooth, with age becoming roughened with thin, close, reddish-brown, roundish scales. TW1GS—Slender, smooth, pale orange colored to reddish-brown with short lateral wart-like branches, with resinous taste. LEAF-SCARS—Scattered on rapidly grown shoots, very numerous and strongly decurrent, minute, triangular, with a single bundle-scar; also on short wart-like branches, smaller and densely clustered. BUDS—Scattered along last season's twigs, on older growth at the ends of the short lateral branches, small, about 1 mm long, spherical, reddish, shining. FRUIT—Ovate, oblong cones, about 144-% inch long on short, stout, incurved stalks, persistent on trees throughout winter. SCALES—thin, about a dozen or fewer in number. COMPARISONS—The American Larch or Tamarack as it is more com- monly called by woodsmen is hardly to be confused with any other tree except the European Larch [Larix decidua Mill.; L. europaea DC.]. The European Larch is a species adapted to dryer situations than the American form. It is readily distinguished by its stouter, yellower twigs, larger cones, about 1 inch long, with numerous cone _ scales (see lower twig in plate). DISTRIBUTION—Low lands, shaded hillsides, borders of ponds; in New England preferring cold swamps; sometimes far up mountain slopes. Labrador. Newfoundland, and Nova Scotia, west to the Rocky mountains; from the Rockies through British columbia, northward along the Yukon and Mackenzie systems, to the limit of tree growth beyond the Arctic circle; south along the mountains to New Jersey and Pennsylvania; west to Minnesota. IN NEW ENGLAND—Maine, New Hampshire and Vermont—abundant, filling swamps acres in extent, alone or associated with other trees, mostly Black Spruce; growing depressed and scattered on Katahdin at an altitude of 4,000 ft.; Massachusetts—rather common at least north- ward; Rhode Island—not reported. IN CONNECTICUT—Absent near the coast; rare in the eastern part of the state; Union, Tolland; becoming occasional westward and fre- quent in Litchfield county. WwooD—Very heavy, hard and strong, rather coarse-grained, very durable in contact with soil, bright light red with thin nearly white sapwood; largely used for the upper knees of small vessels, fence posts, telegraph poles, railroad ties, in cabinet making and for interior finish of buildings. AMERICAN LARcIt European Larcu (lower twig only) oo or DN NEW ENGLAND TREES IN WINTER. WHITE SPRUCE Cat, Skunk or Labrador Spruce. Picea canadensis (Mill.) BSP. P. alba Link. HABIT—A tree 40-75 feet in height with a trunk diameter of 1-2 ft.; trunk straight, slowly tapering, branches numerous, slightly ascending or nearly horizontal, with numerous lateral, generally somewhat pendant branchlets, spread in more or less well marked dense planes, forming a broad-based pyramidal head; foliage bluish-green. BARK—Gravyish to pale reddish-brown; on young trunks and branches smoothish or slightly roughened becoming in a relatively late stage flaky with small closely appressed scales.
