pointed, uniform in colour. It is a native of 

 North America; flowering ill May. 



In the eleventh species, the bulb is the size 

 of a hazelnut : the scape simple, round, jointed, 

 upright, bearing one or two flowers, a foot and 

 half in height : the leaf single, nerved, upright, 

 with the tip hanging down, two feet long: the 

 border of the larger petals white, suborbiculate, 

 with a point ; claws green on the outside, yellow- 

 within, dotted with black : the smaller petals se- 

 veral times shorter and less : claw s convex on the 

 outside, green, concave within, dotted with 

 brow n, the length of the larger ones, but nar- 

 rower ; segments lanceolate, divaricating, a line 

 in length, the middle one of the three a little 

 longer, white dotted with brown. It is a native 

 of the Cape. 



It varies in the shape of the larger petals, and 

 much in the colours, as blue, purple, yellow, 

 white, and spotted. 



The twelfth has the leaves channelled aud 

 convoluted, not only at the base, as in the other 

 species, but the whole length of them ; they are 

 aw 1- shaped at the tip, and shorter than the scape : 

 the flowers are blue, with emarginate petals. It 

 is a native of the South of Europe. 



There are varieties with blue flowers, with vio- 

 let-coloured flowers, with white flowers, with 

 purple flowers, with yellow flowers, with, blue 

 standard petals and white falls, with blue standards 

 and vellow falls, with striped (lowers, the broad- 

 leaved w ith blue flowers, the broad-leaved purple- 

 flowered, the ssveet-scented blue-i'owcred, the 

 sweet-scented purple flowered, with variegated 

 sweet-scented flowers, and the double-flowered. 



The thirteenth has a fleshy root, the thickness 

 of the thumb, spreading horizontally near the 

 surface, blackish on the out side, reddish and 

 spongy within, the upper part covered with nu- 

 merous ridged fibres, the lower part sending 

 down many long, whitish, wrinkled, stringy- 

 roots : the leaves from the root two or three 

 feet long, upright, an inch or more in breadth, 

 striated, having a prominent longitudinal mid- 

 rib, equal to the scape, deep green, smooth : 

 stem-leaves shorter, forming a sheath at the bot- 

 tom : scapes from one to three feet in height, 

 upright, alternately inclined from joint to joint, 

 round or flatted a little, smooth and spongy: the 

 peduncles axillary, flat on one side, and smooth ; 

 each sustaining two or three flowers, the two outer 

 (when there are three) having one sheath, and 

 middle flower two. It is common in most parts 

 of Europe; flowering at the end of June, or the 

 beginning of July. 



The fourteenth species has a thick, tufted, 

 fibrous root : the leaves grass-green, when broken 

 emitting a strong odour, not much unlike that of 



hot roast beef al the 6rs( scent. They arc acute 

 aud nerved. hotter than the scape ; which 



is single, cylindrical, but angular on one side, 

 jojnted, sheathed with alternate spathaccous' 

 -. two feet high, bearing several flowers. 

 It is a native of France, 8tc. 



Tlu fifteenth has the root white within, black 

 without, the thickness of the thumb, having 

 white fibres, and bristly at top, with the remains 

 of leaves: the scape compressed, upright, joint- 

 ed, sheathed with alternate ka\e-, many-power- 

 ed, the length of the leaves, or a little higher, a 

 foot in length: the leaves narrow, sharp, curved- 

 ill at the tip, nerved and smooth, as is the whole 

 plant : the spathes membranaceous, acute, 

 brownish, shorter than the peduncles, very thin 

 at the edge and tip : the peduncles two or three 

 inches long, round, slender, upright, one-flower- 

 ed; the flowers elegant, but without scent : claws 

 of theouterpctals channelled, green on the out- 

 side, yellow on the inside, streaked with dark 

 purple: border flat, rounded-ovate, blunt, quite 

 entire, pale at the base, then blue with deep-blue 

 streaks : inner petals spatulate, blunt, upright, 

 shorter, bluer and streaked. It is a native of 

 Virginia, flowering here in June and July. 



The sixteenth species lias the scape jointed, 

 bifid at the top, or simple, many-flowered, higher 

 than the leaves, two feet in length : the leaves 

 alternate, sheathing; the upper ones gradually 

 shorter : the flowers blue, large. Mr. Curtis re- 

 marks, that it has, for the most part, a stalk 

 unusually crooked or elbowed. It is a native of 

 North America, flowering in May and June. 



The seventeenth has the scape round or round- 

 ish, covered with the sheaths of leaves, many- 

 flowered, longer than the leaves, a foot high : 

 the leaves falcated, acute, striated, nerved: spathes 

 membranaceous at the edge : the larger pe- 

 tals dilated at the base with dusky veins ; lesser 

 snowy-white, with yellowish veins at the base : 

 stigmas snowy-white. From its being the high- 

 est of the species of Iris cultivated in gardens, 

 Mr. Curtis has named it Tall Iris. It is a na- 

 tive of the Levant, flowering in July. 



The eighteenth species has tufted fibrous roots, 

 from which arise many grass-like leaves about 

 nine inches long ; from between them come out 

 the stalks, which arc shorter than the leaves, and 

 support oncpurple (lower w ith blue standards. It 

 flowers in May, and is a native of North America. 



The nineteenth has an oval bulbous root, from 

 which come out five or six pale-green leaves, 

 hollowed like the keel of a boat, about six inches 

 long, and one inch broad at the base, ending in 

 points : between these the fiowcr-stalk . 

 which is seldom above three inches high, sup- 

 porting one or two flowers, inclosed ia spathes ;
