^96 19. GALEOBDOLOX LUTEUM. [CL. XIY. 



gialla. — Engl. Ydloic arcJtangcl, Weasel s7ioui, — Swed. 



This plant appears in our forests at the end of May, "with a 

 knotty root, from which rises a four-cornered stem, its lower 

 part being of the form of a root, furnished with reflex hairs, 

 and from one foot to a foot and a half hioh. The leaf-stalks 

 stand opposite to one another, are furnished with long, soft, 

 white hairs, and are half an inch, and even somewhat longer. 

 The leaves are ovate, unequally crenated, and the teeth are 

 furnished with a small point. At the base they are almost 

 cordate, in other parts they are hairy, of a dark green, 

 sometimes spotted with white, an inch long, and not quite 

 so broad. The uppermost are much smaller, and without 

 stalks. They surround the flowers, which stand by fours 

 and sixes in verticilli, and are surrounded, beside the stem 

 leaves, by smaller bristle-shaped leaves. The calyx has a 

 short stalk, is smooth, and properly has two lobes. The 

 upper lip forms an almost erect, long pointed tooth. The 

 lower lip consists of four teeth, which are also pointed, and 

 almost bristle-shaped. The yellow corolla is two-lipped : 

 the upper lip is arched, without a stalk, and furnished with 

 jointed hairs : the under lip consists of three flat, small, and 

 spotted laciniac. These brownish red sjx>ts are the nedaro-stig- 

 mata : the nectary is the surface of the gynobasis : the lower 

 part of the tube of the corolla, furnished with hairs, forms 

 the nectarilf/ma. Four soft haired filaments, broader below, 

 stand on the tube of the corolla : two are shorter than the 

 other two. They carry four anthera3 with double loculi, 

 and are nearly as long as the upper lip of the corolla. 

 The pistillum is cleft at the top : the stigmata are pointed. 

 Four three-cornered, longish caryopses are persistent in the 

 bottom of the calyx, and contain, like all the Labiata?, the 

 erect embryon, without any albuminous matter.

This plant is so nearly related to the genera LecmuruSy 

 Gahnpsh, and Lamium, that it is sotnctimes rla-^sed with the
