The yew family (Taxaceae) is represented by two genera. 

 Of the true yews (Taxus), 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 pisijerd) ; and the Hinoki cypress ( Chamaecyparis 

 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 Chamaecy-paris 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 

 (Jtmiperus), 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-
