1164. Elecampane, Inula Helenium. 



G.M. 33:541 and 38:477.-Keller savs it has deep golden 

 yellow, fringed, half-drooping rays. Rays are commonly 

 said to be entire, but B.M. 1907 shows 2 minute teeth, 

 and in B.R. 4:334 the fringes are more than a quarter 

 of an inch long. This is said to be the only cult, species 

 that does not seed freely. The Garden pictures an 

 orange variety. 



Hobkeri, C. B. Clarke. Height 1-2 ft. : Ivs. 3-4 in. 

 long, sessile or narrowed into very short petioles, ob- 

 long-lanceolote, acute at the base, minutely toothed, 

 glandular: heads 2.H-3V^ in. across: rays "pale yellow," 

 according to Hooker. Himalayas. B.M. 6411 (rays pure 

 yellow). — Fls. orange-yellow, according to J. W. Man- 

 ning. J. B. Keller says it flowers in Aug. and Sept., and 

 has bright yellow fringed rays. However, in B.M. 6411 

 the rays have only 3 minute teeth.

hlrta, Linn. Lvs. netted-veined, lanceolate or ovate- 

 oblong, the lowest narrowed at the base, the others 

 rounded at the base and half-clasping. Eu., N. Asia. 

 — Keller says it grows 15-18 in. high and fls. July-Aug. 



ensifdlia, Linn. Lvs. with numerous somewhat par- 

 allel nerves, narrowly linear-lanceolate, involucral parts 

 appressed, not spreading. Eu., N.Asia. G. M. 41:559. — 

 Keller says it grows 6-8 in. high and fls. July-Aug. Rook- 

 ery plant; blooms first year from seed if sown early.

 South American : trees or shrubs : lvs. entire, usually

lONOPSlDIUM (Greek, violet-like). Cniciferce. I. 

 acaiile is a pretty, tufted little plant, growing 2 or 3 

 inches high and bearing numerous small 4-petaled, lilac 

 fls. from spring to fall. It is a half-hardy perennial 

 from Spain and N. Africa, but is treated as' an annual. 

 It is desirable for edgings in moist, shady jil.-ices, and 

 for rockeries. In rich garden soil tl].- [.hints make 

 numerous runners. The fls. are almut '_ in. aiinss. 1 on 

 each stalk. They open white and turn iilac-. Tlir plant 

 has been advertised as the Dianioinl Flc.w.r l,y seeds-

 Cochlearia, a genus whose limits are very uncertain.

 are produced so freely and over so long a period that it 

 is sometimes necessary to destroy the flower spikes, 

 which are out of all proportion to the number of lvs.

lonopsis consists of tropical herbs without pseudo- 

 bulbs, having very short stems, with few, narrow, 

 sheathing, coriaceous lvs. : sepals subequal, erect, 

 spreading, the dorsal one free, the lateral ones united 

 into a short spur behind; petals like the dorsal sepals; 

 labellum united to the base of the column, middle lobe 

 large, expanded, 2-3 times as long as the sepals, 2-lobed; 

 column short: pollinia 2: fls. small, in simple racemes 

 or much-branched panicles. 



paniculita, Lindl. Lvs. thick and channelled, linear 

 lanceolate, keeled, 2-3 in a cluster and about 6 in. long: 

 panicle much branched and spreading, loaded with in- 

 numerable fls. of a delicate texture: sepals and petals 

 very short, sharp-pointed, the petals wider: labellum 

 very large, pubescent at base, with a 2-lobed rounded 

 limb, which in some is almost entirely white, while in 

 others it has a spot of purple or yellow on the disk.
