FAMILY 1. PINACEAE. PINE FAMILY. 



Mostly evergreen resiniferous shrubs or trees, typically conic, with 

 flaky or brittle bark. Leaves narrow and solitary, or usually several to- 

 gether, each group with a sheath at the base. Ovulate aments with bracted 

 scales. Mature ovulate cone of dry scales. Seed often samara-like. 



1. PINTJS [Tourn.] L. Leaves needle-like, in 2's or 3's, sheathed at the 

 base, each with 2 fibro-vascular bundles. Cones spreading: scales at length 

 woody and spreading or reflexed, each with a dorsal, usually spine-armed 

 appendage. Seeds samara-like. PINE. 



1. P. caribaea Morelet. Tree with coarse, flaky bark, branched near the top: 

 leaves in 2's or 3's, 18-30 cm. long, or sometimes shorter, bright-green: cones 

 broadly conic when closed, ovoid or oblong-ovoid when open, 8-14 cm. long or

 [E. K.] (Bah., Cuba.) CARIBBEAN-PINE. 



CLASS II. ANGIOSPERMAE. 



Carpel, or pistil, formed by the union of the margins of one, 

 or of several, rudimentary leaves ; within the cavity thus formed the 

 ovules are borne and the seeds are matured. 



Cotyledon 1 : leaf-blades with the primary or lateral veins parallel : stem endogenous. 



1. MOXOCOTYLEDONES. 



Cotyledons typically 2 : leaf -blades with the veins netted : 

 stem exogenous. 2. DICOTYLEDOXES. 



SUBCLASS 1. MONOCOTYLEDONES. 



Stem consisting of a ground mass of soft tissue in which bundles 

 of wood-cells are irregularly placed. Early leaves alternate. 



Order PANDANALES. 



Perennial, aquatic or marsh herbs, with elongate rootstocks. Leaves 

 with narrow blades. Flowers in narrow racemes or globular spikes. Peri- 

 anth of scales or bristles. Androecium of 2-7 stamens. Gynoecium 1- or 

 2-carpellary. Fruit nut-like. 



FAMILY 1. TYPHACEAE. CAT-TAIL FAMILY. 



Racemes solitary and terminal, subtended by deciduous bracts, the 

 staminate portion uppermost, Perianth of bristles. Pistil stipitate : stigma 

 spatulate, oblong or rhomboidal. 



1. TYPHA L. Erect herbs with sheathed stems. Leaves with erect linear 

 blades. Racemes cylindric, the pistillate portion brown.
