48 TREES AND SHRUBS 
recurved; acorn proper an inch in diameter. From Southern Europe. The 
variety dvevicrenata is from Palestine. The acorn-cups are an article of com- 
merce and largely used in tanning. 
* Quercus virens, Azton. Live-OAK. Southern States, from Southern 
Virginia south along the coast or in low grounds; biennial-fruited, large tree, 
furnishing a most durable and valuable timber; branchlets hairy; oblong and 
obtuse leaves, smooth and shining on upper surface and hoary on lower; fruit 
on a long peduncle. There are two varieties. The hardiness here of both the 
species and its varieties is more than doubtful. 
The following are found in the Park invoices and recognized in the Arbore- 
tum Muscaviense, but so far as we can see are not to be found (at least under 
the same names) in the Prodromus of De Candolle: 
Q. ajudaghiensis, Stevens; cf the Q. rubra group. 
Q. Afghanistanensis, zh. 
Q. Hartwissiana, Stevens; of which Q. Jéerica of the gardens is quoted 
as a synonyme. 
Q. Pannonica, #/h. Catalogue. HUNGARIAN OAK, 
Q. pectinata, ort. Said to be an elegant variety and,near Q. Robur 
pedunculata filictfolia. 
The remaining names on the Park invoices we have no sufficient material for 
determining, and hence for the present they are wholly obscure to us, though 
doubtless in most instances well known to propagators :—atropurpurea, Bombyx 
glabra, concordia, Fordit, Hudsonica. Under Q. Robur pedunculata there are 
given zigra, nigricans, and rubjcunda. Besides the above there are zodz/is, 
Speensis, ? sanguinea, Zungin splendens, and heterophylla Hentzet ? 
EBENACE. Ebony Family. 
Hard-wood trees; leaves entire and alternate; petals united into a more or 
less lobed corolla; ovary with a single seed hanging in each cell; berry with 
large, hard-coated seeds. The ebony of commerce is furnished by foreign 
species of this order, 
Diospyros. PERSIMMON. Flowers with the pistils and stamens separate 
or together; 4 to 6 lobes to the calyx and corolla each; stamens variable in 
number according to the species; persistent calyx adhering to the fruit, which 
is edible when fully ripe or after severe frost. 
Diospyros costata. Said to be a new introduction from Japan; unknown 
to us. 
Diospyros Kaki, Zizmm@us. JAPAN PERSIMMON. Parts of the calyx and 
corolla in 4; corolla-lobes obtuse; stamens 16 to 24, adnate to the corolla; 
leaves ovate or elliptical, 3 to 5 inches long by 1% to 2 inches wide. The 
fruit is an important article of food in Japan, where it has long been cultivated
