i^^BiES Link. This differs from Pinus, as above defined, in having the cones 

 pendent, and less decidedly grouped ; the strobiles cjlindrically conical ; 

 the carpels not thickened at the tip ; and the leaves solitary. They are 

 partially scattered in insertion, and more or less 2-ranked in direction. 



Pi'cEA Link. This differs from Pinus and ^^bies, as above defined, in haying 

 the cones erect. The strobile is cylindrical, and has its carpels not thick- 

 ened at the tip. Both carpels and bracteas separate from the axis of the 

 strobile ; and the leaves are obviously 2-ranked in direction. (D. Don.) 



La^rix Tourn. This differs from yi'bies, as above defined, in its leaves being 

 annual, and disposed in groups ; and in having the cones erect. 



Ce^drus Barrelier. This differs from Larix in being evergreen, and in the 

 carpels separating from the axis. The leaves, as in iarix, are disposed in 

 groups, many in a group ; and the cones are erect. Anthers crowned by 

 an elUptical scabrous crest. Strobiles solitary ; crest with coriaceous 

 compressed carpels, which are deciduous. 



CuNNiNGHA^MW R. Br. Male. Catkins grouped. Pollen contained in 3 

 cases that depend from the scale. — Female. Ovules 3. Strobile ovate. — 

 Leaves solitary, scattered in insertion, more or less 2-ranked in direction, 

 flat, acuminate, and serrulate. 



Da'mmara Rumphius. Male. Catkins solitary. Pollen contained in from 

 5 to 24 cases, pendent from the apex of the scale. — Female. Ovules 2, 

 free. Strobile turbinate. — Leaves ovate-lanceolate, often opposite. 

 * * Sexes [?] dioecious. 



ArauCjU'RIA Jussieu. Male. Pollen contained in from 10 to 20 cases, 

 pendent from the apex of the scale. Ovule solitary, connate with the 

 carpel or scale. Leaves imbricate. 



Sect. n. CuPRE'ssiNiE Richard. 

 Sect. Char. All the kinds evergreen, except Taxodium Rich. Branches 

 inserted scatteredly in most, if not all. Buds not scaly. Flowers of 

 each sex but few in a catkin. Ovule with its tip pointing from the axis 

 of the catkin. 



* Sexes vioncedotis. 

 Thu^ja Rick. Male. Catkin terminal, solitary. Pollen of each flower 

 included in 4 cases, that are attached to the inner face of the scale, towards 

 its base. — Female. Catkin terminal. Ovary connate with the bractea : 

 the two conjoined may be termed a receptacle. Ovules 2 to each recep- 

 tacle. Receptacles semipeltate, imbricated, smooth, or, in some, having a 

 recurved beak near the tip. Seeds inconspicuously winged, or not winged. 

 Cotyledons 2. — Brancblets compressed. Leaves scale-like, closely imbri- 

 cated, compressed. 

 Ca'llitris Traf. Male. Catkins terminal, solitary. Pollen of each flower 

 contained in 2 — 5 cases, attached to the lower part of the scale, which is 

 peltate. — Female. Catkin terminal, of 4 — 6 ovaries, or else receptacles, 

 each spreading at the tip, and disposed upon so short an axis as to seem, 

 in the state of fruit, the valves of a regular pericarp, at which time each has a 

 mucro near the tip. Ovules 3 to many to each ovary, or receptacle. Seed 

 winged. — General appearance like that of the kinds of cypress. Branches 

 jointed. Leaves minute, scale-shaped, opposite or whorled, situated under 

 the joints of the branches. 

 Cupre'ssus L. Male. Catkin terminal, solitary. Pollen of each flower 

 contained in 4 cases, attached to the scale on the inner face at the lower 

 edge. Scales peltate. — Female, Ovaries each connate with the bractea, 

 thus constituting a receptacle. Ovules to each receptacle 8 or more. 

 Strobile globose. Receptacles, as included in the strobile, peltate, having 

 an obscure tubercle at the tip ; disposed collaterally, not imbricately. Seeds 

 compressed, angular j affixed to the narrow basal part of the receptacle. 

 Cotyledons 2. — ^Leaves appressedly imbricated. 

 Taxo'dium Rich. Male Catkins disposed in a pyramidal compound spike.
