200 CLASS TRIANDRIA. 



grass (ANTHOXANTIITTM odoratum), which is found in blossom 

 in May ; to this the pleasant smell of new made hay is chiefly 

 owing ; its odour is like that of clover. This plant is separa- 

 ted from the other grasses on account of its having but two 

 stamens. This is the kind of grass which is used in this coun- 

 try as a substitute for the Leghorn grass, in the manufacture 

 of hats. The first hat of the kind was made a few years 

 .since by an ingenious female in the town of Wethersfield, 

 Connecticut ; since which time, many hats, not inferior to the 

 best Leghorn, have been made from the same material. 



The Catalpa, an elegant tree with flat, cordate, or heart- 

 shaped leaves, is indigenous to the Southern United States ; its 

 white flowers, striped with purple, grow in panicles similar to 

 the Horse-chesnut. Only one species is found in North 

 America. 



Order Trigynia, 



Contains the genus Piper. One species of which, the nigrum, 

 is the common black pepper. The cayenne pepper belongs 

 to the genus CAPSICUM, which is found in the eighth class. 

 The Piper genus has neither calyx or corolla. 



We have in the course of this lecture remarked upon the 

 use of botanical terms, with the necessity of their being in one 

 common language ; we have considered the few groups into 

 which the classes of Linnaeus may be arranged with the names 

 of all the classes, and the characters of each; and lastly, have 

 given a sketch of the two first classes, with some examples 

 under each of their orders. In doing this, we have been 

 obliged to pass by many plants which had an equal claim to 

 notice, but as knowledge must be gained by the observation of 

 particular cases, we have thus selected some, in order that you 

 may be prepared to examine the others, with pleasure and 

 advantage.
