I could name, unless I had chosen to adopt brevity, a multitude of other hybrid plants.* 

 It is more than probable, that Nature at first created but a few species, and by the inter- 

 mixture of these arose the extensive genera, or families of plants, and even by the union of 

 nearly allied genera, other kinds were produced : for Nature proceeds " from simple to more 

 compound/' 



The variety of plants arises, I think, chiefly from sexual intercourse : for, unless this were 

 the case, when removed into different quarters, and changed in their soil, the variety of the 

 Species would return to their original appearance ; but nothing of this sort takes place, as is daily 

 seen in our most esteemed varieties of culinary plants. 



* Koelreuter, who for thirty years made experiments upon plants, performed what he calls " a complete metamorphosis of one natural 

 species of plants into another;*' which shews, that in seeds as well as in buds, the embryon proceeds from the male parent, though the form 

 of the subsequent mature plant is in part dependent on the female. 



M. Koelreuter impregnated a stigma of the'NicoTiANA Rustica (Common English Tobacco) with the farina of the Nicotiana Panicu- 

 lata (Panicled Tobacco), and obtained prolific seeds from it. 



With the plants, which sprung from these seeds, he repeated the experiment, impregnating their pistilla with the farina of the Nicoti- 

 ana Paniculata. 



As the mixed plants, which he thus produced, were prolific, he continued to impregnate them for many generations with the farina of the 

 Nicotiana Paniculata, and they became more and more like the male parent, till he at length obtained six plants in every respect per- 

 fectly similar to the Nicotiana Paniculata, and in no respect resembling their female parent the Nicotiana Rustica. 



This ingenious experimentalist took the farina of the Digitalis purfurea (Purple Foxglove), and impregnated the pistillum of the 

 Digitalis lutea (Small Yellow Foxglove), and he obtained an hybrid, which, instead of being either purple or yellow, was striped, and 

 proved perennial, although its father is a biennial plant. Fide Memoir in the Transactions of the Academy of Petersburgh, for the 



year 1782.

One of the most extraordinary hybrids, unless it can be better referred to some of those very remarkable sportings of Nature, is seen in 



the Peloria. 



This hybrid is so named from the Greek word vrtkopcc, wonder, or astonishment, for when first presented to Linnaeus by one of his 

 students in botany, he was greatly surprised to see an Antirrhinum Linaria (Common Toad-flax) in the shape of its leaves, its manner 

 of growth, in its peculiar smell, but its flowers, instead of being personate, with one spur-like nectary, and four unequal stamina, had five 

 equal stamina, five spur-like nectaries, a corolla formed like an inverted funnel, with the neck of it revolute, more nearly, therefore, resem- 

 bling Erica (Heath) in its fructification, but yet differing from this as to the number of stamina. 



Being a mule from distinct genera, it cannot be propagated by seeds, but only by cuttings. 



The Quadrangular Passion-flower appears to us to be an offspring betwixt the Winged and the Common Blue Passion, hence it most 

 resembles its father the Winged Passion-flower in its foliage, but its mother the blue in its flower. Vide our Picturesque Botanical Plates of 

 the several Passion-flowers, and description. 



Vide also our Notes to the description of the Carnation, where a Mule Pink is in one of the notes particularly mentioned.
