* In utricularia (bladder-wort) the roots are loaded with membranaceous bladders. 
f It hath been observed in many plants, as in ruta , dictamnus albus$ 
saxifrage parnassia , &c. that at the proper times the stamina make the first ad¬ 
vances by bowing down in their turns to the female; but in collinsonia canadensis f 
7iigella i damascena , spartium scoparium , and some others, the lady seeths to make 
the first advance, by bowing first to one or more of her husbands for a day or two, 
and then to the others. But what is still more remarkable ; the common berberry 
hath six erect stamina resting on the petals, under whose concave tops are sheltered 
the anther; and on touching the inside of the filament near its base, with a 
bristle or fine wire, the stamen instantly incurvates, so as the anthera to embrace 
the stigma*—In the kalmia the ten stamens lie round the pistil, like the radii of a 
wheel, and each anther is concealed in a nieh of the coral to protect it from cold 
and moisture; these anthers rise separately from their niches, and approach the 
stigma of the pistil for a time, and then recede to their former situations. 
X In salvia , the singular cross thread of the stamina constitutes the essential 
character of the genus : the rudiments of two stamina appear in the mouth of the 
flower, but have no anthCrse.— Sage and clai'y are distinct plants by other writers, 
but by Linnseus, they both come under the genus salvia , notwithstanding some 
little difference in the flower.
