16. NIGifeLIiA, FENNEL-FLOWER. (Name from the black seeds.) ^ 

 Garden plants from Eu. and Orient ; with leafy stems, the leaves finely di- 

 vided, like Fennel ; known by having the 5 ovaries united below into one 

 5-styled pod. Seeds large, blackish, spicy ; have been used as a substitute 

 for spice or pepper. 



If. Damascena, Common F. or Kagged-Ladt. Flower bluish, rather 

 large, surrounded and overtopped by a finely-divided leafy involucre, like the 

 other leaves ; succeeded by a smooth inflated 5-celled pod, in which the lining 

 of the cells separates from the outer part. 



H". satlva, Nutmeg-Flowee. Cult, in some old gardens ; has coarser 

 leaves, and smaller rough pods. 



17. AQUILEGIA, COLUMBINE. (From aquila, an eagle, the spurs of 

 the petals fancied to resemble talons.) IJ. Well-known, large-flowered 

 ornamental plants : flowers in spring and early summer, usually nodding, so 

 that the spurs ascend. 



* North American species ^ with long straight spurs to the corolla. 



A. Canadensis, Wild C. Flowers about 2' long, scarlet and orange, 

 or light yellow inside, the petals with a very short lip or blade, and stamens 

 projecting. Common on rocks. 



A. Sklnneri, Mexican C, is taller, later, and considerably larger-flow- 

 ered than the last, the narrower acute sepals usually tinged greenish ; otherwise 

 very similar. Cult. 



A. C8Brtllea, Long-sphrked C, native of the Rocky Mountains, lately 

 introduced to gardens, and worthy of special attention ; has blue and white 

 flowers, the ovate sepals often 1^', the very slender spurs 2' long, the blade of 

 the petals (white) half the length of the (mostly blue) sepals, spreading. 



* * Old World species, with hooked or incurved spurs to the corolla. 



A. vulgaris, Common Garden C. Cult, in all gardens, l°-3° high, 

 many-flowered ; spurs rather longer than the blade or rest of the petal ; pods 

 pubescent. Flowers varying from blue to purple, white, &c.„greatly changed 

 by culture, often full double, with spur within spur, sometimes all changed 

 into a rosette of plane petals or sepals. 



A. glandulbsa. Glandular C. A more choice species, 6' - 1° high, 

 with fewer very showy deep blue flowers, the blade of the petals white or white- 

 tipped and twice the length of the short spurs ;. pods and summit of the plant 

 glandular-pubescent. 



A. Sibirica, Siberian C. Equally choice with the last, and like it ; 

 but the spurs longer than the mostly white-tipped short blade, as well as the 

 pods, &c. smooth. 



18. DELPHtNIUM, LARKSPUR. (From the Latin name of the dol-

 flowers scattered on the spreading branches, blue, varying to pink or white ; 

 pod smooth. 



D. Aj&cis, Rocket L. More showy, in gardens, and with similar flowers 

 crowded in a long close raceme, and downy pods ; spur shorter : some marks on 

 the front of the united petals were fancied to read AIAI = Ajax. 



» » Perennials, with 4 separate petals and 2-5, mostly 3 pistils. 



D. grandifldrum, Grbat-fl. L. of the gardens, from Siberia and China, 

 is 1° - ^'^ high, with leaves cut into narrower linear divisions ; blue flowers, 1^'
