BAYBERRY FAMILY 177 
at apex. Teeth not large. Leaf-stalks longer than the leaves and _flat- 
tened laterally. A slender tree, very common throughout our area. 
March-May. 
6. P. nigra, L. Buiack Poprar. Leaves almost triangular (deltoid), 
tapering to a slender point at the apex. When young the leaves are . 
somewhat silky. Base of leaf bluntly rounded, sometimes rounded in. 
A large tree, naturalized, found in the Hudson and Delaware Valleys. 
April-May. 
7. P. deltoides, Marsh. (Fig. 6, pl. 24.) Cortonwoop. Leaves 
broadly triangular (deltoid), abruptly pointed at apex, generally rounded 
out at the base. Leaf-stalk about as long as the leaf-blade. Along 
streams, throughout our region. March-May. 
P. pyramidalis, Rosier. LOMBARDY POPLAR, with its broad, deltoid leaves 
and erect branches, is found wild occasionally. 
Famity I].—MYRICACEAE. Bayperry Faminy 
Shrubs with alternate leaves which are aromatic. Catkins, 
small and erect, both pistillate and staminate flowers found on 
the same plant or one form only on a single plant. In the aments 
a single flower only is found at the axil of a bract. Staminate 
flower consists, usually, of 4 to 6 stamens, the filaments somewhat 
united. ach pistillate flower subtended by 2 to several bractlets. 
Ovary 1-celled; fruit a small berry-like nut. 
t MYRICA, L; 
Shrubs with pear-shaped leaves, broadest at the apex, or with linear 
lance-shaped leaves. After the fall of the catkins the branches of some 
species bear an abundance of whitish, waxy, berry-like nuts. 
1. M. Gale, L. (Fig. 7, pl. 25.) Swrer Garr. Leaves pear- 
shaped, about 4 times as long as broad. Toward the apex the leaves are 
notched while the basal half of the border is generally smooth. Com- 
mon at the borders of streams, ponds and swamps. April-May. 
2. M. carolinensis, Mill. (Fig. 8, pl. 25.) WaxBeErry. Shrub, 
rather larger than the preceding (2 to 8 ft. high). Leaves similar to 
No. 1, but without teeth at the borders. Berries very numerous, light 
grayish-white, waxy to the touch. In early times in this country these 
berries furnished an important supply of wax to the settlers. In sandy 
soil, moist or dry. April-May. 
3. M. asplenifolia, L. (Fig. 5, pl. 25.) Swerer Fern. (Comptonia 
perigrina, Coulter.) Shrub, 1 to 2 ft. high, very leafy, the leaves and 
stems decidedly aromatic. Leaves linear-lance-shaped, the borders cut 
into a number of shallow lobes giving the leaves a fern-like appearance. 
Stipules half heart-shaped. The pistillate aments at the leaf axils have 
a bur-like appearance, the staminate aments dangle from the ends of the 
branches. Dry hillsides and sterile soil, frequent in our region.
