    Of Flowers. uy panfion, of which Dr. Grew hath thefe Varieties, viz. the Clofe Couch, as in Rofes, and feveral other double Flowers; the Concave-Couch, as in Bla- taria ; Flora alba, the Angle Plait, as in Peafe-Bloffoms ; the double Plait, as in Blew-bottles, 6>V. the Couch and Plait together, as in Marigolds’ Baizes, Sec. The Row!, as in Lady Bower ; the Spire, as in Mallows] and laftly, the Plait and Spire together, as in Convolvulus Doronici Folio. As to the Stamina with their Apices and Stylus (called the Attire by Dr. Grew) they are admirable, whether we confider their Colours, or their Make, but efpecially their Ufe, if it be as Dr. Grew, Mr. Ray, and others imagine, namely, as a Male Sperm, to impregnate and fructify the Seed ; ■which Opinion is corroborated by the ingenious Obfervations of Mr. Samuel Moreland, viz. All Flowers, in general, or at lead the greated Part of them, are fur- nilhed with Chives, Tops, and Pidils. The Farina, or fine mealy Powder, which is at its proper Seafon, died out of thofe Thecas or Apices; Sem ini formes, which grow at the Top of the Stamina, does in fome Meafure perform the Office of a Semen Mafculi- num, by dropping upon the Outfide of the Uterus or Vafculum Seminale, and impregnate the included Seed, &c. But Dr. Moreland was of Opinion, that the Seeds which come up in their proper Involucra, are at fird, like the unimpregnated Ova of Animals ; * that this Farina is a Congeries of feminal Plants one of which mud be conveyed into every Ovum, before it can become prolifick. That the Stylus, as Mr. Ray, or the upper Part of the Pidulum, as Mr. Tournefort calls it, is a Tube defigned to convey thefe fe¬ minal Plants into their Ned in the Ova •, and that there is fuch a vaft Provi- don made thereof, becaufe of the Odds there are, whether one of fo many fhall ever find its Way into, and thro5 fo narrow a Conveyance. For in the Corona imperialism where the Uterus or Vafculum Seminale of the Plant dands upon the Centre of the Flower, from the Top of which dands the Stylus \ the Vafculum Seminale, and Stylus together, reprefenting a PidiF lum ; round this are planted fix Stamina ; upon the Extremities of each of thefe are Apices, fo artfully fixed, that they turn every Way with the lead Blad of Wind, being in Height almod exactly equal to the Stylus, about which they play, and which in this Plant is manifedly open at Top ; it is hollow all the Way, and upon the Top of the Stylus there is a Sort of Tuft, confiding of pinguid Villi, fuppofed to be placed there to catch and detain the Farina, as it flies out of its These ; and that the Rain either wadies it, or the Wind fhakes it down the Tube, till it reaches the Vafculum Seminale. In the Caprifolium or Honey Suckle, there rifes a Stylus, from the Rudi¬ ments of a Berry, into which it is inferted, to the Top of the monopeta- lous Flower ^ from the Middle of which Flower are lent forth feveral Sta- * Phi, franf Fo- 287, mina,
