As to the perianth this view is supported by the existence of one species, the Iris falcifolia, the perianth of which consists of six equal parts. But species with six stamens are wholly lacking.
I find these fruits very pleasent particularly the yellow currant which I think vastly preferable to those of our gardens. the shrub which produces this fruit rises to the hight of 6 or 8 feet; the stem simple branching and erect. they grow closly ascociated in cops either in the oppen or timbered lands near the watercouses. the leaf is petiolate of a pale green and resembles in it's form that of the red currant common to our gardens. the perianth of the fructification is one leaved, five cleft, abreviated and tubular, the corolla is monopetallous funnel-shaped; very long, superior, withering and of a fine orrange colour. five stamens and one pistillum; of the first, the fillaments are capillare, inserted into the corolla, equal, and converging; the anther ovate, biffid and incumbent. with rispect to the second the germ is roundish, smoth, inferior pedicelled and small; the style, long, and thicker than the stamens, simple, cylindrical, smooth, and erect, withering and remains with the corolla untill the fruit is ripe. stigma simple obtuse and withering. the fruit is a berry about the size and much the shape of the red currant of our gardins, like them growing in clusters supported by a compound footstalk, but the peduncles which support the several berries are longer in this species and the berries are more scattered. it is quite as transparent as the red current of our gardens, not so ascid, & more agreeably flavored. the other species differ not at all in appearance from the yellow except in the colour and flavor of their berries.
The flowers of the blue flags have a perianth of six segments united below into a tube. The three outer parts are dilated and spreading, or reflexed, while the three inner usually stand erect, but in most species are broad and colored like the outer ones.
"That water finds its way by preference through the fibro-vascular bundles even in the more delicate parts, is shown by placing the cut peduncle of a white tulip, or other large white flower, in a harmless dye, and then again cutting off its end in order to bring a fresh surface in contact with the solution, when after a short time the dye will mount through the flower-stalk and tinge the parts of the perianth according to the course of the bundles."
I cannot conceive how the engages ever assimilated this animal with the buffaloe for there is not greater analogy than between the horse and the frog. this animal is found in greatest numbers in the sandy open parts of the plains, and appear in great abundance after a shower of rain; they are sometimes found basking in the sunshine but conceal themselves in little holes in the earth much the greater preportion of their time. they are numerous about the falls of the Missouri and in the plains through which we past lately above the Wallahwallahs. The Choke Cherry has been in blume since the 20th inst. it is a simple branching ascending stem. the cortex smooth and of a dark brown with a redish cast. the leaf is scattered petiolate oval accute at its apex finely serrate smooth and of an ordinary green. from 11/2 to 3 inches in length and 13/4 to 2 in width. the peduncles are common, cilindric, and from 4 to 5 inches in length and are inserted promiscuously on the twigs of the preceeding years growth. on the lower portion of the common peduncle are frequently from 3 to 4 small leaves being the same in form as those last discribed. other peduncles 1/4 of an inch in length are thickly scattered and inserted on all sides of the common peduncle at wright angles with it each elivating a single flower, which has five obtuse short patent white petals with short claws inserted on the upper edge of the calyx. the calyx is a perianth including both stamens and germ, one leafed fine cleft entire simiglobular, infrior, deciduous. the stamens are upwards of twenty and are seated on the margin of the flower cup or what I have called the perianth. the filaments are unequal in length subulate inflected and superior membranous. the anthers are equal in number with the filaments, they are very short oblong & flat, naked and situated at the extremity of the filaments, is of a yelow colour as is also the pollen. one pistillum. the germen is ovate, smooth, superior, sessile, very small; the Style is very short, simple, erect, on the top of the germen, deciduous. the stigma is simple, flat very short.

The segments of the perianth also closed on the pistil, but more slowly than the stamens. These insects were not uncommon beneath stones. I found one cannibal scorpion quietly devouring another. Shelley, Lines on Mt. Blanc. I have lately heard that Capt.
The perianth is not changed in double flowers, hence the genus or family may be often discovered by the calyx, as in Hepatica, Ranunculus, Alcea. In those flowers, which have many petals, the lowest series of the petals remains unchanged in respect to number; hence the natural number of the petals is easily discovered. As in poppies, roses, and Nigella, or devil in a bulb. Phil. Flower de Luce.
I found here a species of cactus, described by Professor Henslow, under the name of Opuntia Darwinii "Magazine of Zoology and Botany" volume 1 page 466, which was remarkable for the irritability of the stamens, when I inserted either a piece of stick or the end of my finger in the flower. The segments of the perianth also closed on the pistil, but more slowly than the stamens.
Sometimes terms of greater generality were devised; as perianth, to include the calyx and corolla, whether one or both of these were present; pericarp, for the part inclosing the grain, of whatever kind it be, fruit, nut, pod, etc. And it may easily be imagined, that descriptive terms may, by definition and combination, become very numerous and distinct.
