CAM 



Campylospermous. When a seed or seed- 

 like fruit is so rolled up as to have a fur- 

 row in the longer diameter of one side. 



Campylotr&pal. An ovule, one of whose 

 sides grows much faster than the other, 

 so that while the chalaza (which see) re- 

 mains at the hilum, the foramen (which 

 see) is brought nearly into contact with 

 it, 



Canaliculate. Channeled or furrowed, like 

 the petioles of many leaves. 



Gancellate. Latticed; resembling lattice- 

 work; comprised of veins only, all the 

 parenchyma or intervening web being 

 absent; as where the single fibers, of which 

 the whole plant of Byssus cancellatus is 

 composed, cross each other. 



Candidus. A pure white; but not so clear 

 as snow-white. 



Canescens. More or less gray, verging on 

 white; grayish-white; hoary; a term ap- 

 plied to hairy surfaces. 



Ganescent. Hoary; approaching to white. 



Canker. A rather indefinite term, used to 

 denote a disease resulting in the slow de- 

 cay of trees or other plants attacked by 

 it. 



Cannabinacece, (Cannabinece, Hempworts.) 

 A natural order of Monochlamydeous 

 Dicotyledons, belonging to Lindley's TJr- 

 tical Alliance. They are rough-stemmed 

 herbs with watery sap, alternate and 

 lobed leaves with stipules, and small, in- 

 conspicuous flowers. The plants have 

 some flowers with stamens without pis- 

 tils, and others with pistils without sta- 

 mens. The staminate flowers are in 

 clusters called racemes or panicles; 

 the calyx is herbaceous and scaly; the 

 stamens are few and opposite the sepals; 

 the filaments are filiform. The pistillate 

 flowers are in spikes or c-oiies, with a sin- 

 gle sepal; the ovary is one-celled, and 



CAP 



contains a solitary, pendulous ovule; 

 there are two stigmas. The fruit is a 

 single-seeded nut; the embryo is hooked 

 or spiral, without albumen. The plants 

 are natives of the temperate parts of the 

 East Indies and Europe. They posseas 

 narcotic qualities and yield valuable 

 fibers. Cannabis sativa yields the well- 

 known Hemp, one of our most valuable 

 fibers. It is imported in large quanti- 

 ties from Russia, and is produced in a 

 small way in this country. The plant 

 grows naturally in the cooler parts of In- 

 dia, and there develops narcotic qualities, 

 which seem to reside in the resin which 

 covers the leaves. What are called 

 Hemp Seeds, used for the food of birds, 

 are in reality Hemp fruits, each contain- 

 ing a single seed. ffumulus Lupulus, 

 the well-known Hop, possesses both ton- 

 ic and hypnotic properties, that is, a 

 power to produce sleep. The scales of 

 the Hop heads are covered with resinous 

 matter, which has an aromatic odor. 

 There are but two known genera in the 

 order, Cannabis and ffumul.ua;, and two 

 species. 



Cannacece. The Indian Shot family, a nat- 

 ural order of Epigynous Monocotyledons 

 belonging to Lindley's Amomal Alliance. 

 The name of Marantacece is also given to 

 the order. See Marantacece. 



Canua. Grayish white or hoary; a term 

 applied to hairy surfaces. 



Cap. The convex part of an Agaric or 

 other similar Fungi. 



Capittaceous, Capillary. Having the form of 

 a thread; very slender; resembling a 

 hair. 



Capillaceoux, Capillary. Very slender, like 

 a hair. 



Capillary-multifid. Divided into slender, 

 hair-like segments.
