16 LABIATE AND PERSONATE FLOWERS. 



five bristly points, four ovules, at length becoming foup 

 naked seeds. From the centre of these ovules arises 

 a single style, terminated with a bifid summit or stig- 

 ma. The corolla, when removed, is open at the bot- 

 tom, and tubular for the admission of the style, which " 

 grows up within it. 



Four naked seeds in the bottom of the calyx, and a 

 gaping open corolla is characteristic of the labiate or- 

 der. They have also very generally square stems, 

 and flowers disposed in whorls or apparent circles 

 round the upper part of the stem. Some of them, as 

 the Rosemary and Sage, have only two stamens. In 

 Sage there are only two filaments supporting two oth- 

 ers in an horizontal, moveable posture, and producing 

 an anther only at one of the extremities. In Self- 

 heal (Prunella vulgaris) all the filaments are forked, 

 but only one of the prongs bears an anther ; most of 

 these plants are highly aromatic, such as Marjoram, 

 Thyme, Basil, Mint, Hyssop, Lavender, &c. or else 

 strong-smelling and foetid, as the Deadnettle, Catmint, 

 Black Horehound, &sc. Some, such as the Selfheal, 

 have but little odor of any kind. 



In the second order of labiate flowers the seeds are 

 numerous, and produced in a capsule, commonly of 

 two cells and two valves, as in the Foxglove, Toad- 

 flax (Antirrhinum linaria), and Snapdragon (An- 

 tirrhinum majus) ; the corolla is personate, having the 

 two lips closed and joined. From the lower lip of the 

 Toadflax depends a spur. In this plant, the Fox- 

 glove, Bignonia, Pentstemon, and many others, there 

 exist the rudiments of a fifth stamen, in accordance 

 then with the five divisions of the calyx and corolla. 

 In that curious variety of the Toadflax, named Pelo- 

 ria by Linnaeus, the corolla appears in the form of a 

 cone, terminated above by a prominent border of five 

 divisions, and below producing five spurs in place of
