RETINOSPORA. (LRetinospora squarrosa leptoclada, Siebold ; Chamecyparis 
squarrosa leptoclada, Endlicher.) A large bush from Japan, and much culti- 
vated there. The foliage is of a bright glaucous-green color, closely arranged

Retinospora lycopodioides, Standish. C1iuB Moss-LIKE RETINOSPORA. 
(Retinospora monstrosa, Hort.) Tree from Japan. Leaves arranged all 
around the branches, and either sharp-pointed or scale-like. Hence, from the

Retinospora obtusa, Svebo/d. OBTusE-LEAVED JAPAN RETINOSPORA. 
(Chamecyparis obtusa, Endlicher ; Chamepeuce obtusa, Zuccarini; Retino- 
spora Fusinoka, Zuccarint.) A lofty tree, forming the greater part of the 
forests in the mountains of Nippon, Japan. The timber, owing to its white- 
ness and compactness, takes a polish and lustre almost like silk, says Gordon, 
In consequence it is used by the Japanese in erecting temples and in making 
sacred utensils. Hardy here, but requiring some shade to bring out the full 
beauty of its leaves. There are the following distinct varieties: argentea, 
Fortune ; which has some of the leaves and branchlets silvery white, contrast- 
ing with the green. aurea, /ortune,; has golden-colored spray and leaves 
which contrast well with the green. Of this variety there are other forms. 
compacta, //oofes ; is dwarfish, with a regular conical outline and fan-shaped 
branchlets terminating the branches; a well-marked variety. gracilis, Hoopes ; 
produced by Messrs. Otto & Achelis, of West Chester, Pa.; is a pale yellowish- 
green form, with slender, erect branches. 
Retinospora pisifera, Siebo/¢d. PEA-FRUITED RETINOSPORA. (Chame- 
cyparis pisifera, Endlicher.) From the island of Nippon, Japan. Tree small 
and slender. The branches, branchlets, and foliage together form a dense 
mass. ‘The fruit is small, and of “‘numerous imbricated scales.”’ The Park 
has, as varieties of the above, variegata and nana variegata. 
Retinospora plumosa, ort. PLUME-LIKE JAPAN RETINOSPORA. (e- 
tinospora pisifera plumosa, Hort.) Is a compact form, with small, bright- 
green leaves and small branches. Hardy, and a rapid grower. Of this there 
are these varieties in the Park: argentea, //ort. SILVER-PLUMED RETINO- 
SPORA; with the tips of the shoots at first perfectly white, but turning green 
later. aurea, //ort.; branchlet tips of a permanent golden color. Hardy. 
This is the same as the 2. fzszfera of the gardens. 
Retinospora squarrosa, Szebo/d. SQUARROSE-LEAVED RETINOSPORA. 
(Chamecyparis squarrosa, Endlicher; Cupressus sqguarrosa, Lawson.) A 
small, slender-branched shrub or tree from Japan, with bluish-green leaves 
which are recurved at the tips. Hardy here, and handsome. It, too, has 
produced some varieties, though none of any great value. 
The following forms are in the Park, but their permanency can yet hardly 
be stated : 
Retinospora cristata, //oofes. A compact dwarf, with the young branch- 
lets in tufts and of a golden-yellow color. 
Retinospora elegantissima, Hoofes. ‘ Habit dwarf and regular; growth 
compact and delicate; foliage yellow-tinted.”
