IS-t OF THE FULCRA, 



kind. (89) The flower-stalks of Cardiospermum HaUca- 

 cahum bear tendrils ; but a most singular kind of ten- 

 dril, if it may so be called, which certainly has a right 

 to the name o^ fulcrum, is found in the Arinona hex- 

 apetala, Linn. SuppL 270. The flower-stalk of this 

 tree forms a hook, and grasps the neighbouring branch, 

 serving to suspend the fruit, which is very heavy, re- 

 sembling a bunch of grapes, and indicates the plant in 

 question to be either a Michelia or an Uvaria, 



6. Glanduk, a Gland, is defined by Linneus as a little 

 tumour discharging a fluid. Such are abundant on 

 the stalk and calyx of a Moss Rose,/ 123, Curt. 

 Ma^. t. 69, and between the serratures of the leaf of 

 SalLv pentandra. Bay -leaved Willow ; also on the 

 footstalks of Viburnum Opulus, (90) Engl Bot. t. 

 332, and various species of Passion-flower. The 

 liquor discharged is in the first-mentioned instances 

 resinous and fragrant, in the latter a sort of honey. 



7. Pilus,/. 124. A Hair. This, according to the Lin- 

 nean definition, is an excretory duct of a bristle-like 

 form. Such it undoubtedly is in the Nettle, Urtica, 

 Engl. Bot. t. 148, and t. 1236, whose bristles are tu- 

 bular and pervious, having each a bag of poison at its 

 base, like the fang of a serpent ; as well as in numerous

 eller's Joy, climbs by means of its leaf stalks, which twine like 

 tendrils round their supporters.] 



(90) [Guelder Rose, or Snow ball. Several species of 

 Cassia have large glands on the leaf stalks. Ribes Floridum has 

 both surfaces of the leaf covered with them.]
