 lea^ t. 1013, and some maritime grasses, 

 have scarcely more tiian the rudiment of 

 a stipula. Old writers call this organ in 

 grasses hv a peculiar name Ugula, and 

 others denominate it mt^mbrana folioriun, 

 but both terms are superfluous. A curious 

 instance of stipulas supplying the place of 

 leaves is observable in hathyrus Aphaca, 

 t. 1 167, which has only one or two pair 

 of real leaves on the seedling plants, ajid 

 those soon disappear, serving chiefly to 

 prove, if any proof were wanted, tlia.t the 

 rest are true stipulas.
