(IN examining 7 Trifolium alpe re, medium, and pratenfe, Y have found 
them agree in very “many re pets. "To prevent tautology, I have 
taken care to avoid mentioning in their defcriptions any circum- 
{tance common to all thefe three fpecies; but, for the fake of a 
more complete knowledge of the genus, I fhall here in one place 
enumerate them all. However, as I have not had an opportunity 
of feeing Trifol. alpefre living, I cannot with abfolute certainty 
determine the nature of its ftamina, piftilla, feed-veffels, and feeds ; 
but what I fhall mention with refpeét to thefe parts of fru&ifica- 
tion, I have chiefly taken from Trifol, medium, and particularly from 
the pratenfe. But as to the re know they : agree in the following 
circumftances. — IA
