TO BOTAXY. 165 



is a plane fructification fastened for the most part to 

 the margin of the leaf*. 



In Mossee, the capitulurn or little head is a cap- 

 sule, containing seeds in the form of fine dust. 



In Grasses, spicula, a* little spike, is a partial one; 

 the arista is tortile, twisted, when it has a twisted 

 joint in the middle. Articulus, a joint, is the part 

 of the columns that lies between two geniculi, or 

 knots. 



A radiate compound flower consists of disk and 

 radius. The radius is composed of irregular coroi- 

 lulae in the circumference ; and the disk of smaller 

 corollulae, that are for the most part regular. 



A decompound flower contains within the same 

 calyx lesser calyces, that are each of them common 

 to many flowers ; as in Sphaeranthus. 



The Corolla is said to be equal, when its parts are 

 equal in figure, magnitude and proportion ; unequal, 

 when the parts answer in proportion, though not in 

 magnitude, so that the flower comes not to be regu- 

 lar; regular, when it is equal in respect to the figure, 

 magnitude, and proportion, of the parts ; irregular, 

 when the parts of the limb differ in figure, magnitude, 

 or proportion. Rictus, a gaping or grinning, is the 

 gap or opening between the two lips of the corolla. 

 Faux, the gorge or gullet, is the opening of the tube 

 of the corolla. Palatum, the palate, is a gibbosity or 

 bunching out in the faux of the corolla. Calcar, 

 a spur, is a nectarium extending in a cone in the 

 hinder part of the corolla. The Corolla, is urceo- 

 late, pitcher-shaped, when it is inflate and gibbous 



* The terras explained here, and in the following para- 

 graphs, respect such circumstances of the parts .of fructifica- 

 tion as concern rather the specific differences than the classic 

 or generic ones ; and we have therefore followed Linnaeus in 

 subjoining them to this head, notwithstanding that some few 

 of them have been already mentioned and explained in the 

 first part of this work.
