130 ENGLISH BOTANY. 



"Wales at one time, and is now practised at Llanberis. The square stones of the 

 floors are ornamented by being crossed at right angles with two broad black lines, 

 ■which somewhat resemble mosaic-woi'k. This effect is produced by strongly rubbing 

 the stone with a handful of leaves of the Foxglove, when the juice dyes this black 

 stain. 



Tribe IY.— ANTIIMIHINEJ3. 



Corolla tubular, bilabiate, usually saccate or spurred at the 

 base on the outer side ; upper lip covering the others in bud. 

 Stamens 4, didynamous, rarely with a small scale, representing 

 the fifth stamen. Leaves alternate, or the lower ones often verti- 

 cillate or opposite. 



GENUS IV.— A. NTIRRHINUM. Tonrnef. 



Calyx 5-partite. Corolla tubular, bilabiate and personate ; 

 tube saccate at the base on the outer side ; limb with the upper 

 lip erect, 2-lobed, the lower spreading, 3-lobed, with the middle 

 lobe the smallest, and with a large hairy palate pressed 

 against the upper lip and closing the mouth of the flower. Sta- 

 mens 4, didynamous, included ; anthers 2-celled. Capsule 2-celled, 

 obliquely ovoid, with the upper cell opening by a single pore 

 and the lower by 2, or globose and with each cell opening by 

 a single pore. Seeds numerous, minute, not winged. 



Herbs or undershrubs, with most of the leaves alternate, but 

 the lower ones generally opposite. Flowers generally handsome, 

 solitary and axillary, or disposed in racemes. 



The name of this genus of plants is derived from two Greek words, am (anti), 

 instead of, and piv (rin), a snout ; so called because the flower in some of the species 

 is said to resemble the snout of a calf.
