reflect the petals. 4th. To erect these peduncles when the germ was fecundated. We may reason upon this by observing, that all this apparatus might have been spared, if the filaments alone had grown longer; and that thence in these flowers that the filaments are the most unchangeable parts; and that thence their comparative length, in respect to the style, would afford a most permanent mark of their generic character.]

65 Woo'd with long care, CURCUMA cold and shy
Meets her fond husband with averted eye:?Four beardless youths the obdurate beauty move?With soft attentions of Platonic love.
With vain desires the pensive ALCEA burns,?70 And, like sad ELOISA, loves and mourns.
The freckled IRIS owns a fiercer flame,?And three unjealous husbands wed the dame.?CUPRESSUS dark disdains his dusky bride,?One_ dome contains them, but _two beds divide.?75 The proud OSYRIS flies his angry fair,
Two houses hold the fashionable pair.
[Curcuma. l. 65. Turmeric. One male and one female inhabit this flower; but there are besides four imperfect males, or filaments without anthers upon them, called by Linneus eunuchs. The flax of our country has ten filaments, and but five of them are terminated with anthers; the Portugal flax has ten perfect males, or stamens; the Verbena of our country has four males; that of Sweden has but two; the genus Albuca, the Bignonia Catalpa, Gratiola, and hemlock-leaved Geranium have only half their filaments crowned with anthers. In like manner the florets, which form the rays of the flowers of the order frustraneous polygamy of the class syngenesia, or confederate males, as the sun-flower, are furnished with a style only, and no stigma: and are thence barren. There is also a style without a stigma in the whole order dioecia gynandria; the male flowers of which are thence barren. The Opulus is another plant, which contains some unprolific flowers. In like manner some tribes of insects have males, females, and neuters among them: as bees, wasps, ants.
There is a curious circumstance belonging to the class of insects which have two wings, or diptera, analogous to the rudiments of stamens above described; viz. two little knobs are found placed each on a stalk or peduncle, generally under a little arched scale; which appear to be rudiments of hinder wings; and are called by Linneus, halteres, or poisers, a term of his introduction. A.T. Bladh. Amaen. Acad. V. 7. Other animals have marks of having in a long process of time undergone changes in some parts of their bodies, which may have been effected to accommodate them to new ways of procuring their food. The existence of teats on the breasts of male animals, and which are generally replete with a thin kind of milk at their nativity, is a wonderful instance of this kind. Perhaps all the productions of nature are in their progress to greater perfection? an idea countenanced by the modern discoveries and deductions concerning the progressive formation of the solid parts of the terraqueous globe, and consonant to the dignity of the Creator of all things.]
[Alcea, l. 69. Flore pleno. Double hollyhock. The double flowers, so much admired by the florists, are termed by the botanist vegetable monsters; in some of these the petals are multiplied three or four times, but without excluding the stamens, hence they produce some seeds, as Campanula and Stramoneum; but in others the petals become so numerous as totally to exclude the stamens, or males; as Caltha, Peonia, and Alcea; these produce no seeds, and are termed eunuchs. Philos. Botan. No. 150.
These vegetable monsters are formed in many ways. 1st. By the multiplication of the petals and the exclusion of the nectaries, as in larkspur. 2d. By the multiplication of the nectaries and exclusion of the petals; as in columbine. 3d. In some flowers growing in cymes, the wheel-shape flowers in the margin are multiplied to the exclusion of the bell-shape flowers in the centre; as in gelder-rose. 4th. By the elongation of the florets in the centre. Instances of both these are found in daisy and feverfew; for other kinds of vegetable monsters, see Plantago.
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. Bot. p. 128.]
[Iris. l. 71. Flower de Luce. Three males, one female. Some of the species have a beautifully freckled flower; the large stigma or head of the female covers the three males, counterfeiting a petal with its divisions.]
[Cupressus. l. 73. Cypress. One House. The males live in separate flowers, but on the same plant. The males of
