Pyrus intermedia, Z£4rhart. INTERMEDIATE WHITE BEAM-TREE. From 
Europe, especially the colder parts; with ovate lobed or deeply-toothed leaves 
which are white hairy beneath; flowers in branching flat-topped clusters ; edible 
fruit globose. 
Pyrus Japonica, 7hiundberg. JAPAN QUINCE. (Cydonia FYaponica, Per- 
soon.) Lowshrub, from Japan; thorny, smooth, with large scarlet, rose-colored, 
or white flowers, which appear earlier than the oval or oblong, bluntly-toothed 
leaves; young fruit with 2 ovules in each cell; mature fruit green, hard, 
knotty, and worthless. A common showy plant, making beautiful hedges. 
Pyrus salicifolia, Zivneus. W1ILLOW-LEAVED PEAR-TREE. About 20 
feet high. Native of Siberia, Caucasia, and Persia. Leaves narrowly lance- 
shaped, sharp-pointed, and white hairy on the under surface, blade thrice as 
long as the leaf-stalk; flowers few in a cluster; buds covered with a white 
wool. 
Pyrus sambucifolia, Chamissoand Schlechtendah/. Small tree, native along 
our northern borders, and closely related to the American Mountain Ash (see 
above), but with oblong, obtuse, blunt- or sharp-pointed leaves. Once regarded 
as a form of P. Aucuparia, and still known in some gardens as P. hybrida, 
Monch. 
Besides the species enumerated above, the following well-known trees 
belong here: Pyrus communis, the CoMMON PEAR; Pyrus Cydonia, the 
COMMON QUINCE; Pyrus malus, the APPLE-TREE. 
Rosa. Rose. + Shrubs, usually prickly, with compound leaves of gener- 
ally 3 to 12 toothed leaflets; stipules (small leaf-like organs) united to the 
base of the common leaf-stalk; flowers large and conspicuous, either solitary 
or in clusters, terminating the branches; seed enclosed in an urn-shaped 
fleshy cup, which is contracted at the top and crowned by the calyx-lobes. A 
well-defined natural group, with over 200 recognized species, of which nearly 
or quite a hundred are now in cultivation, and out of these an innumerable 
host of varieties has been produced. Besides the sense of the beautiful which 
is gratified by this “Queen of Flowers,” the rose is also an important source 
of employment to thousands who manufacture rose-water and attar. The 
wood is valuable for certain fine purposes, and it has also been proposed as a 
substitute for boxwood for the engraver’s use,—probably a poor substitute. 
We cannot attempt even a list of the varieties in a brief synopsis like this. 
Hence we will simply enumerate the common native and foreign forms the Park 
has or ought to have. 
* Rosa blanda, Aiton. EARLY WILD Rose. Styles separate, with the 
stigmas closing the mouth of the calyx-tube; not a climber; prickles, if any, 
weak ; leaflets 5 to 9, oblong and blunt-pointed, whitish or hairy on the under 
surface; flower-stalk and calyx smooth; mature fruit nearly globular. Native. 
Rosa canina, Jinneus. DoG Rose. European plant, now sparingly natu- 
ralized here, much resembling our native sweetbrier; stipules large, lanceo- 
late, nearly entire; leaflets about 7, oval, smooth, sharp-pointed and sharply 
serrate; pink or whitish flowers in clusters of 3 to 5; prickles stout. 
Rosa Caroliniana, Zinnzus. Swamp Rose. A not rare native, often 
troublesome in low grounds; the distinct styles closing the mouth of the calyx 
with their stigmas; leaflets 5 to 7, lanceolate to oblony, finely toothed except 
at base; calyx and fruit glandular hairy; flowers often many in a cluster; 
prickles rather stout, recurved.
