times with difficulty distinguished. If its stem is small, 

 woody, and subdivided into numerous branches, from 

 the summit nearly to the ground, it is said to be fru- 

 ticose or shrubby, and the Lilac is a very common ex- 

 ample. When the branches annually perish, leaving 

 the main stalk alive, and when the whole shrub is ex- 

 tremely ^lender, as in Pyrola, and Partridge berry, it 

 is Paid to be sujfruticose. If a plant extends itself late- 

 rally, and covers the earth so as to form a turf, it is 

 cmspitose or turfy, and the Moss-pink Phlox subulata, is 

 an example. 



If its cellular texture is abundant, and filled with 

 juices, as in the Ice plant it is said to be succulent. 

 If it thrives only in water it is said to be aquatic, and 

 the Pond Lilly is an example ; if on the margin of the 

 sea, it is maraiime, and the Marsh Rosemary is an ex- 

 ample ; if in sea water, it is marine, and the numerous 

 -Sea weeds are examples. Those plants are said to be 

 native, which have flourished in any particular district, 

 without the aid, and beyond the recollection of man, 

 and those are exotic which were brought from a for- 

 eign country, and cannot be preserved except by cul- 

 tivation. When a foreign plant thrives, and extends 

 itself without culture, it is said to be naturalized. 

 The Dandelion, which is a native of Europe, has be- 

 come extensively naturalized on this continent, and no 

 plant is more common or better known. 



SURFACE. — When the surface of a plant is smooth, 

 without visible hairs or bristles, it is said to be glabrous, 

 and the leaves of Snake head, Chelone glabra, and also 

 of the Elder, are good examples. The term even also 

 denotes smoothness, and is opposed to roughness and 

 irregularity of surface. 



When the surface is so smooth as to glitter or shine.
