50 TREES AND SHRUBS 
Shepherdia argentea, Nv//a//. BUFFALO-BERRY. From the far West. 
Has small oblong leaves, which are green on both sides; scarlet fruit edible, 
but acid, 
- Shepherdia Canadensis, Nétal/, CANADIAN SHEPHERDIA. Small shrub 
which ranges widely over the northern and colder parts of America; leaves I 
to 2 inches long by half as wide, green on upper and silvery and rusty scaly on 
under surface; fruit red, intensely bitter, but sometimes eaten; branchlets also 
rusty scaly. 
ERICACE,. Heath Family. 
A large family of trees and shrubs (few herbs), with simple and usually 
alternate leaves ; flowers mostly regular, and with parts in 4 or 5; petals mostly 
more or less united, sometimes free; stamens as many or twice as many as the 
lobes of the corolla, anthers generally opening by pores at the apex. Prop- 
erties various: astringent, sometimes with volatile oils, sometimes poisonous, 
or again the fruit edible, as in the Blueberries and Huckleberries. Family is 
divided into a number of well-marked saé-orders, which for our purposes must 
be thrown together. 
Andromeda. Calyx free from the 5-celled ovary, the 4- to 5-toothed or 
lobed corolla falling after flowering, but the calyx remaining and becoming 
dry, valvate in the bud. Shrubs. ‘ 
* Andromeda ligustrina, A/whlenberg. A native shrub, 4 to Io feet high; 
obovate leaves thin and green; small globular flowers scaly-pubescent, in 
branching clusters. 
Andromeda Mariana, Z7zz@us. STAGGER-BusH. Flowers in “ um- 
bel-like clusters,” each flower. inch long, cylindrical oval; leaves thick, 
shining, veiny ; leaf-like sepals fall with the leaves. A native shrub, I to 4 
feet high. ‘The popular name is probably derived from the reputed poisonous 
action of the leaves on lambs and calves. 
Andromeda polifolia, Zizneus. Shrub 1 to 2 feet high; native of our 
colder bogs; leaves smooth, entire, glaucous ; margins revolute; corolla nearly 
globular. 
Andromeda speciosa, Michaux. Shrub ranging from North Carolina to 
Florida; 2 to 4 feet high; the white corolla open bell-shaped; deciduous 
leaves I to 2 inches long, oval, sparingly toothed; flowers in clusters along 
the leafless branches of the previous year. This species may be hardy with us. 
It has the following varieties in the Park: viridis, Duhame/,; which is the 
A. cassinefolia of the gardens; and pulverulenta, AZichawx ; a white glaucous 
form, 
See Azalea, under Rhododendron. 
Possibly some of the hardier tree-forms of Arctostaphylos from the Western 
coast might be worthy of trial in the Park, 
Calluna. HEATHER. Bell-shaped corolla 4-parted, persisting and drying 
on the shrub; calyx free from the ovary.
