5. Of Size. . 



Most of the terms which relate to this quali ty are the same as those in common 

 use ; and, being employed in precisely the same sense, do not need explanation. 

 But there are a few which have a particular meaning attached to them, and are 

 not much known in common language. These are, 



1 . Dwarf (nanus, pwmilus, pygmceus) ; small, short, dense, as compared with 

 other species of the same genus, or family. Thus, Myosotis nana is not 

 more than half an inch high ; while the other species are much taller. 



2. Very small (pusillus, perpusillus} ; the same as the last, except that a 

 general reduction of size is understood, as well as dwarfishness. 



3. Low (humilis) ; when the stature of a plant is not particularly small, but 

 much smaller than of other kindred species. Thus, a tree twenty feet high 

 may be low, if the other species of its genus are forty or fifty feet high. 



4. Depressed (depressus) ; broad and dwarf, as if, instead of growing perpendi- 

 cularly, the growth had taken place horizontally ; as some species of Coch- 

 learia, Coronopus Ruellii, and many others. 



5. Little (exiguus) ; this is generally used in opposition to large, and means 

 small in all parts, but well proportioned. 



6. Tall (elatus, procerus) ; this is said of plants which are taller than their parts 

 would have led one to expect. 



7. Lofty (exaltatus) ; the same as the last, but in a greater degree. 



8. Gigantic (glganteus) ; tall, but stout and well proportioned. 



To this class must also be referred words or syllables expressing the propor- 

 tion which one part bears to another. 



1 . 7sos, or equal, placed before the name of an organ, indicates that it is equal 

 in number to that of some other understood : thus, isostemonous is said of 

 plants the stamens of which are equal in number to the petals. De Cand. 



2. Anisos, or unequal, is the reverse of the latter : thus, anisostemonous would 



be said when the stamens are not equal in number to the petals. 



3. f Meios, or less, prefixed to the name of an organ, indicates that it is some- 



thing less than some other organ understood : thus, f mewstemonous would 

 be said of a plant the stamens of which are fewer than the petals. 



4. Duplo, triploy &c., or double, triple, &c., signify that the organs to the name 

 of which they are prefixed are twice or thrice as numerous or large as those 

 of some other. 



The terms which express measures of length are the following : 



1. A hair's breadth (capillus, its adjective capillaris) ; the twelfth of a line. 



2. A line (linea, adj. linealis); the twelfth part of an inch. 



3. A nail (unguis) ; half an inch, or the length of the nail of the little finger.
