The Coniferales comprise, in our range, the Yew (Taxaccac), 
the Pine (Pinaceae), the Bald Cypress (Tarodiaceae), and the 
Cypress (Cupressaceae) Families. The hard, bony seed of the 
Yew is surrounded by a fleshy disk which resembles a red berry. 
The genera of the Pine Family all bear their seeds in cones. In 
the Juniper (Juniperus) the fleshy cone-scales are so fused ‘to- 
gether that the result appears like a berry. The Botanic Garden 
collection includes Pines, Larches, Hemlocks, Spruces, California 
Bigtree (Sequoia gigantea), Bald Cypress (Taxrodium distichum), 
Cryptomeria, Cedars (Cedar of Lebanon, Cedrus Libani; the Atlas 
Cedar, C. atlantica), and others. 
ANGIOSPERMS 
Dicotyledons without Petals (Apetalous) 
Southwestward from the Gymnosperms are Angiospermous 
trees having flowers without floral envelopes (calyx and corolla), 
and usually borne in cone-like catkins or aments (the so-called 
ament-bearers or Amentiferac). In the Hickory, Oak, Chestnut, 
and others only the staminate flowers are in catkins. Most o 
these forms are wind-pollinated, including the Birches, Alders, and 
others, of the Birch Family (Betulaceae). Here, also, are the 
Beeches and Oaks of the Beech Family (Fagaceae) ; the Walnuts 
and Hickories, of the Walnut Family (/uglandaceae); and the 
Elms (Elm Family, Ulmaceae). 
South of the east-west walk, leading to the White Oak Circle, 
are the Mulberries and Paper-Mulberry, wind-pollinated trees of 
the Mulberry Family (Moraceae), and the insect-pollinated Fig 
of the same Family. : 
The insect-pollinated Willows and Poplars (Willow Family, 
Salicaceae), are planted along the Brook (toward the south) in 
order to secure the streamside conditions of a natural habitat. 
Dicotyledons with Separate Petals (Polypetalous ) 
The plants in all the Orders on the east side of the Brook, be- 
ginning with the Magnolias (Magnoliaceae) and proceeding down 
through the Garden to the Dogwoods (Cornaceae), have flowers 
with separate petals, usually in 5’s, less commonly in 4’s..
