310 PINE FAMILY. 



2. ABIES. Leaves persistent, linear or short needle-shaped, borne directly on the 



shoots of the season, over which they :ire thickly and uniformly scattered. 

 Sterile catkins in the axils of the leaves of the preceding year. 'Fertile cat- 

 kins solitary, maturing in the autumn of the same year; their scales thin and 

 even^ never prickle-bearing. 



3. LARIX. Leaves all deciduous in autumn, soft, short needle-shaped, in spring, 



developed very many in a dense cluster from axillary buds of the previous 

 summer (Lessons, p. 71, fig. 139), those on shoots of 'the season similar but 

 scattered. Cones as in Abies, the scales persistent. 



4. CEDRUS. Leaves as in Larix, but rigid and persistent. Cones globular, 



large, of very broad thin scales, which at length fall away from the axis. 



II. CYPRESS FAMILY. These have both kinds of flowers 

 in short often globular catkins of few scales ; the fertile making a 

 globular or ovate small cone, which is often fleshy when young, 

 sometimes imitating a berry. The branches appear and the shoots 

 prow on without the intervention of any scaly buds. Leaves often 

 opposite or whorled, sometimes scale-like and adnate to the branch. 



1. Scales of the globular cone with a pointed bract behind each wedge-shaped scale, 

 parly coli triii y with its back. 



5. CRYPTOMERIA. Cone terminating a leafy branch, the recurved tip of the 



bract and awl-shaped lobes of the top of tlie scales projecting. 



2. Scales of the fruit simple, nn bract behind them. 



* Fruit a soil of cone, dry and hard when mature : flowers monoecious, rarely dioecious. 

 -- Leaa-s thin and delicate, Ji 'it, dtciduous. 



6. TAXODIUM. Two kinds of flowers on the same branches; the sterile catkin 



spike-panicled, of few stamens; the fertile in small clusters. Cone globular, 

 firmly closed till mature, of several very thick-topped and angular shield- 

 shaped scales, a pair of erect 3-angled seeds on their stalk. 

 - -i- Leaves evergreen, linear and awl-shaped, alternate, free, destitute of glands. 



7. SEQUOIA. Catkins globular, the scales of the fertile ones bearing several 



ovules. Cone woody; the shield-shaped scales closed Avithout overlapping, 

 and bearing 3-5 flat wing-margined seeds hanging from the upper part of 

 their stalk-like ba--e. 



-*-- Leares evergreen, opposite., awl-fh'iped and scale-shaped (the former on the 

 more vigorous lengthening shoots, thr /"Her clottly imbricated and decussate on 

 the succeeding branchftts). commonly icith a resinous gl:ind on tfie back. Seeds 

 and omits erect : cotyledons only 2 or 3. 



8. CUPRESSUS. Cones spherical; the shield-shaped scales closing by their 



well-fitted margins, 7iot overlapping, separating at maturity, each scale bear- 

 ing two or usually several ovules and winged or wing-margined seeds, its 

 broad summit with a central boss or short point. 



U. THUJA. Cones oblong or globular, the scales not shield-shaped but concave 

 and fixed by their base, overlapping in pairs, pointed if at all from or near 

 their summit, spreading open at maturity, each bearing a single pair of 

 ovules and seeds, or rarely more. 



# * Fruit berr-if-likr : Jbnrers cmninnnfii diaic/oiis. 



Jft. JUXIPEIM'S. (\itkin* very small, lateral: the fertile of 3-fi fieshv scales 

 growing together, and ripening into a sort of globular berry, containing 1-3 

 bony seeds. Leaves evergreen, opposite or whorled. 



III. YEW FAMILY. Distinguished by having the fertile 

 catkin, if it may be so called, reduced to a single terminal flower, 

 consisting of an ovule only, surrounded by some bracts, ripening 

 into a nut-like or drupe-like seed : eoh ledons only 2. There is 

 nothing answering to the scales of a pine-cone. Leaf-buds s-caly as 

 in the true Pine Family. Flowers mostly diuvious, axillary. 



11. TAXI'S. I.-avcs linear, appearing more or I<^- 2-ra'iked, green both si-li--. 

 Po'.h kinds of catkins, if such they may be calle-l, are small axillary buds
