dulous ; in colour, sometimes tinged with red, 

 sometimes with brown. They are either sim- 

 ple or composite. 



STIPULES. Stipules are small leaves of un- 

 certain form, rising at the base of the foot-stalk, 

 of larger leaves, and sometimes adhering to the 

 leaf. It " must be observed whether they are 

 adherent or non-adherent, deciduous or perma- 

 nent ; in form, whether pectinated, capillary, 

 lanceolated, dentated, serrated, or coniform ; 

 concave or convex, biforked, sloped, wide or 

 narrow, awl-shaped, or needle-shaped. Their 

 margin may be edged with glands or fringed 

 with hair, and their surface, either under or 

 upper, cottonous or glandulous. Their colour 

 should also be studied.

 stalk is attached to the leaflets, the leaflet is 

 called sessile. To the leaf itself a stalk is ne- 

 cessarily attached, which is defined as strong or 

 weak, long or short, naked or clothed, spinous, 

 cottonous, glandulous, or thorny. It must be 

 observed, also, whether the leaf-stalk is bordered 

 with a membrane, flattened or round, cylindri- 

 cal or channelled ; that is, hollowed by a canal 

 which extends throughout its length. 



THE LEAF. The leaf of the rose-tree is, with

 of several leaflets, attached by petiolules, or 

 minor foot-stalks, to a common peduncle. The
