im OF THE FULCUA, 



and Lagurus ovatusy t. 1334. In Aria asrulea, t: 

 750, a few minute hairs supply its place, while Sesie- 

 ria aerulea, t. 1613, and some maritime grasses, have 

 scarcely more than the rudiment of a stipula. Old 

 writers call this organ in grasses by a peculiar name 

 Ugula, and others denominate it membrana foliorum:, 

 but both terms are superfluous, A curious instance 

 of stipulas supplying the place of leaves is observable 

 in Lathyrus Aphaca, t, 1167, which has only one or 

 two pair of real leaves on the seedling plants, and 

 those soon disappear, serving chiefly to prove, if any- 

 proof were wanted, that the rest are true stipulas. 



Remarkably scariose or dry membraneous stipulas 

 are seen in lUecebrum Paronychia^ J^l. Grac, t. ^46, 

 and in the genus Pinus, 



2. Bract ea. The floral leaf, a leafy appendage to the 

 flower or its stalk. It is of a variety of forms, and 

 someiimes green, sometimes coloured. The Lime- 

 trees, Tilia europtea, f. Ill , t, 610, and parvifo^ 

 lia, t. 1705,havea very peculiar oblong pale floral leaf, 

 attached to the flower-stalk. (86) The Lavenders,/ 

 118, see Curt. Mag, t. 400 and 401, have coloured 

 bracteas, and the Purple-topped Clary, Salvia Hor- 

 minum, FL Gnec. t, 20, exhibits a gradation from 

 the proper leaves to green bracteas, and from them to 

 coloi' cd ones, which last are barren, or unaccompa- 

 nied by flowers. Hence I am induced to believe this
