.M. 33:541 and 38:477. Keller says it has deep golden 

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

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

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

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

 at does not seed freely. The Garden pictures an 

 ange variety. 



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

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

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

 andular: heads 2%-3% in. across; rays "pale yellow," 

 ;cording to Hooker. Himalayas. B.M. 6411 (rays pure 

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

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

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

 ie rays have only 3 minute teeth. 



BB. Outer involucral parts lanceolate and leafy. 

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

 )long, the lowest narrowed at the base, the others 

 mnded 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- 

 lei nerves, narrowly linear-lanceolate, involucral parts 

 ^pressed, not spreading. Eu., N. Asia. G.M. 41:559. 

 eller says it grows 6-8 in. high and fls. July- Aug. Rock- 

 ~y plant; blooms first year from seed if sown early.

IOCHKOMA (Greek, violet-colored). SolanacecK. This 

 snus includes 2 handsome flowering shrubs cult, out- 

 ;oors in S. Calif, and under glass in Europe. They are 

 'ill-growing, and bear clusters of as many as 20 tubular, 

 rooping fls., each 1-1 % in. long and less than % in. 



across at the mouth, which seems to have 10 short lobes, 

 but 5 of these are shorter, and are really appendages in 

 the sinuses between the 5 typical lobes. lochroma is a 

 genus of about 18 American species, mostly tropical and 

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

 large: fls. violet, blue, white, yellowish or scarlet: ber- 

 ries globose or ovoid, pulpy. 



A. Fls. indigo-blue. 



lanceolata, Miers. Shrub, 4-5 ft. high (taller in 

 Calif.), the young branches herbaceous and downy, 

 with stellate hairs: Ivs. alternate, oval or elliptic-Ian-' 

 ceolate, acute, entire, tapering below into a long petiole: 

 umbels supra-axillary and terminal. Equador. B.M. 4338 

 and F.S. 4:309 (as Chcenesthes lanceolata). 

 AA. Fls. scarlet or orange-scarlet. 



fuchsioides, Miers. Lvs. often clustered, obovate, very 

 obtuse, tapering at the base into a short petiole. Peru. 

 B.M. 4149 (as Lycium fuchsioides). 



IONIDIUM. For I. concolor, see Solea. 



lONOPStDIUM (Greek, violet-like). Cruciferce. I. 

 acaule 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 places, and 

 for rockeries. In rich garden soil the plants make 

 numerous runners. The fls. are about % in. across, 1 on 

 each stalk. They open white and turn lilac. The plant 

 nas been advertised as the Diamond Flower by seeds- 

 men. This plant is referred by Index Kewensis to 

 Cochlearia, a genus whose limits are very uncertain. 



acaule, Reichb. (Cochledria acaulis, Desf. ). Lvs. 

 ovate-rotund, heart-shaped at the base ; petioles pro- 

 portionately very long: pods subrotund, notched. B.R.

IONOPS1S (Greek, violet-like). Orchidacece. A small 

 genus of epiphytic orchids, numbering about 10 species, 

 many of which can probably be reduced to varieties of a 

 few species. Most of the species are insignificant, only 

 one or two being cultivated. The fine specimen of /. 

 paniculata figured in the Botanical Magazine has a 

 panicle 10 in. long, 8% in. wide, with 5 branches, and 

 about 80 fls., each three-quarters of an inch across and 

 chiefly white, with violet markings near the center and 

 a dash of yellow. In its native country it is said to re- 

 main in attractive condition from Sept. to May. The fls. 

 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 Ivs. 

 The plants succeed in the warmhouse under the same 

 treatment as Burlingtonias or the more delicate Oncid- 

 iums. 



lonopsis consists of tropical herbs without pseudo- 

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

 sheathing, coriaceous Ivs. : 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. 



paniculata, 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.

 Very variable. 



utricularioldes, Lindl. Lvs. and general habit as in 

 the last: sepals and petals bluntish; spur short; la- 

 bellum almost twice as long as the petals; lobes sub- 

 quadrate-rounded, white, streaked with red veins.
