The yew family (Taxaceae) is represented by two genera. 
Of the true yews (Za«xus), there are: the American yew, or 
ground hemlock; the English yew, and several of its horticul- 
tural forms, the wood of which was highly prized in ancient 
times for the manufacture of bows; and the Japanese yew. 
The cluster-flowered yew (Cephalotaxus) is represented by 
Fortune’s cluster-flowered yew, from northern China, and the 
iraga boku, of the Japanese, from Japan. Other representa- 
tives of this group will be found in conservatory houses nos. 12 
and 13. 
On the westerly corner of the conservatory terrace and in 
the immediate vicinity are located the retinisporas, which are 
so commonly cultivated as decorative plants. There are 
many horticultural forms here represented, but they are all 
variations of two Japanese trees: the Sawara cypress (Cham- 
aecyparis pistfera); and the Hinoki cypress (Chamaecypares 
obtusa). The latter species is frequently used by the Japanese 
in their dwarfing process. The names borne by the various 
horticultural forms have been suggested by some peculiarity 
in coloring or in manner of growth. Other species of the 
genus Chamaecyparis will be found in the low ground along 
the south walk, not far from the south gate. 
On the easterly corner of the conservatory terrace, oppo- 
site the retinisporas, is a part of the juniper, or red cedar 
( Juniperus), collection. The remaining and larger portion 
of this collection will be found on the easterly end of the area 
lying between the driveway and the traffic-road south of the 
conservatories. In these two regions will be found many 
species and varieties of these plants. The common juniper, 
of north temperate regions, is one of these; also the Irish 
juniper, a form of this, of compact and strict habit. The 
red cedar, so common in a wild state in the grounds of the 
Garden, finds representatives in many horticultural forms. 
The low cedar, of North America, Europe and Asia, is a 
pretty dwarf species. The savin juniper, of Europe and 
northern Asia, and its American representative, the prostrate 
juniper, of northern North America, are both neat low-grow-
