Imantophyllum and Qivta synonymous. That 

 they are closely allied we do not doubt Hav- 

 ing flowered them frequently, we find the flow- 

 er! of /. minium (the only species) to beer**, 

 and much larger than Clivia, nobihs, the flowers 

 of which are drooping and of a darker color. 



Weed, Jewell Weed. 

 Our native species of this genus are commonly 

 known as Touch-me-nots, from the sudden 

 bursting of the pods when touched. They are 

 interesting annuals, common in damp grounds 

 throughout the United States. The Balsams of 

 our ^rdens are described under Ealsamma, 

 which see. 



Imphee. See Sorghum. 



Indian Bean. See Catalpa. 



Indian Corn. See Zen. 



Indian Cress. See Tropceolum. 



Indian Cucumber Boot. See Medeola. 



Indian Currant. The common name of the fruit 

 of the Symphoricarpus vulgaris. 



Indian Fig. See Opuntia. 



Indian Grass. See Arundo. 



Indian Hemp. See Apocynum. 



Indian Mallow. A common name of Abutilon 

 avicenna, a troublesome, worthless weed in 

 fields and waste places. It is a native of India, 

 and was introduced into our gardens as an orna- 

 mental plant, but is now naturalized, and a 

 nuisance. 



Indian Millet. One of the popular names of 

 ^ortjhum vulgare, to which species belong Broom 

 Corn, Sweet Sorghum, and other cultivated 

 varieties. 



Indian Pink. See Dianthus Chinens'is. 



Indian Pipe. A common name of the Monotropa 

 uniflora. See Corpse Plant. 



Indian Plantain. The popular name of the 

 genus C'tcalia, common in rich, damp woods in 

 most of the States. 



Indian Poke. Veratrum viride, or White Helle- 

 bore. 



Indian Bice. See Water Rice. 



Indian Shot. See Gamut. 



Indian Strawberry. See Fragaria. 



Indian Tobacco. See Lobdia inftata. 



Indian Turnip. See Ariscnmu. 



India Bubber Tree. See Ficus dastica. 



Indigo. See Ind'ujofera tindora. 



Indigofera. From indigo, a blue dyestuff ; a cor- 

 ruption of Indicum, Indian, and fero, to bear; 

 most of the species produce the well-known dye 

 called Indigo. Linn. Diadelphia-Decandria. Nat. 

 Ord. Fabacece. 



An extensive genus of rather ornamental 

 herbaceous perennials, tender annuals, and 

 evergreen shrubs, grown almost wholly for the 

 commercial value of the dye they produce. 

 /. tinctoria, the species most commonly culti- 

 vated, is a native of the East Indies and other 

 parts of Asia, but it has been introduced into, 

 and become naturalized in, the Southern States, 

 and was formerly extensively cultivated, as was 

 I. anil, the West India Indigo, a stronger grow- 

 ing species, from both of which large quantities 

 of Indigo were made. They are tender shrubs, 

 growing from four to six feet high, with very 



IPO 



pinnate leaves, and axillary racemes of pink 

 and purple flowers. The shrubby species are 

 propagated by cuttings, and the annuals from 



Inga. The South American name of I. vera, 

 adopted by Marcgraff. Linn. Polygamia-Monoscia. 

 Nat. Ord. Fabacece. 



A very extensive genus of ornamental shrubs 

 and trees, numbering upward of one hundred 

 and fifty species, natives of the warmer parts of 

 South America, principally of Brazil and Guiana. 

 The flowers are white, pink, crimson, etc., and 

 are borne in variously-shaped spikes, or in 

 nearly globular heads, growing singly or in 

 clusters from the angles of the leaves. /. pul- 

 cherrima, a native of Mexico, is one of the most 

 beautiful of the genus. The foliage is small- 

 er than most of the species, and is very orna- 

 mental. The tassel-like flowers are of a bright 

 crimson, and very showy. The shape of the 

 flower-heads has given it the name of Bottle 

 Brush. All the species are propagated from 

 cuttings of young wood in summer. Intro- 

 duced in 1822. 



Ink-Berry. The fruit of Ilex (Prinos) glabra, an 

 evergreen shrub, common on the Atlantic coast. 

 lonopsis. From ion, violet, and opsis, like. Linn. 

 Gynandria-Monandria. Nat. Ord. Orchulacece. 



A small genus of free-flowering , low-growing, 

 beautiful little Orchids. They are difficult to 

 manage, and are, therefore, seldom seen in col- 

 lections. 



Inula. A word of doubtful origin, but said to 

 be a corruption of Hdenium. Linn, tyyngenesia- 

 ^Equalis. Nat. Ord. Aslemcece. 



A genus of coarse-growing annuals and her- 

 baceous perennials, not worth growing as 

 flowering plants. I. Hdenium is the Elecampane, 

 common in the roadsides throughout the States. 

 Ipomoea. Morning Glory. From ips, bindweed, 

 and homoios, similar ; alluding to the twining 

 habit of the plants. Linn. Pentandria-Monogynia. 

 Nat. Ord. Gonvdvulacece. 



A very extensive genus of twining plants, con- 

 sisting of hardy and tender annuals, hardy 

 tuberous-rooted perennials, and green-house 

 perennials. They are remarkable for their 

 showy flowers of white, pink, blue, and purple 

 colors. 1. purpurea, with its varieties, is the 

 common Morning Glory of the garden. It is a 

 native of South America, but has escaped from 

 cultivation and become thoroughly naturalized. 

 /. pandurata, Man-of-the-Earth, a native species, 

 having very large tuberous roots, when well 

 established will cover a very large space, and 

 produce an immense number of very large, 

 pure white flowers. They remain open much 

 longer than the annual varieties. /. Mexicana 

 and /. Mexicana alba both bear white flowers, 

 though the seeds of one are black and of the 

 other white. There would seem to be some con- 

 fusion here. The tuberous-rooted species are in- 

 creased by division, by cuttings, or from seeds. 

 /. noctiphyton (which is sold under several other 

 names) is a tropical perennial species, with im- 

 mense pure white, sweet-scented flowers, and 

 is probably identical with /. Bona Nox. The 

 flowers, contrary to the habits of this splendid 

 family, open at night instead of the morning. 

 Being a free bloomer, the effect, especially on a 

 moonlight night, is charming, particularly when 

 it is growing on a tree. This species requires 

 to be taken in during winter. Propagated by 

 cuttings or from seeds. I. Learii, a tender 

 perennial species, is perhaps the most beauti-
