have tubulous empalements of one leaf, which are 

 cut into five fegments at the top, four of which are 

 narrov/, and end in acute points; the other, which 

 is on the upper fide of the liov/er is broader, and is 

 rounded at the point. The tube of the flower is 

 longer than the empalement, and is fwelling and 

 large at the chaps ; the upper lip is broad, eredt, and 

 arched over the tube ; the lower lip is fhorter, and 

 has two fliort fide fegments which are ered:, but 

 the middle fegment is broad, rounded, and indented 

 at the point, and is refiexed back to the tube. It has 

 four ftamina which lie clofe under the upper lip, 

 and are arched in the fame manner-, two of thefe 

 are as long as the ftyle, which Hands in the fame

 juft below the other ; they are terminated by ob- 

 long fummits, which are faftened in the middle to 

 the Ilamina. The ftyle is crowned by a bifid, re- 

 flexed, narrow ftigma ; the flowers appear in June, 

 and are of a fine blue colour ; thefe are each fucceeded 

 by four oblong feeds, which ripen in the empalement. 

 The fecond fort grows naturally in Siberia ; this was 

 fent me by the late Dr. Amman, who was profeflTor 

 of botany at Peterfburgh ; it hath a perennial root. 

 The ftalks are four-cornered, hairy, and rife a foot

 ■which are garnifhed with hairy linear leaves, cut into

 leaves under each whorl ; the tube of the flower is 

 longer, and more equal in fize than that of the for-

This name was given to this genus of jilants by the 

 learned Dr. Boerhaave, profcfTor of botany at Ley- 

 dcn, in honour of Dr. Ruyfch, who was profcflbr of 

 anatomy and botany at Anifterdam. 

 The plants are propagated by feed, which fliould be 

 fown the latter end of March, in a bed of frc(h 

 light earth in an open expofure, and in about five or 

 fix weeks after the plants will appear, when they 

 fliould be carefully cleared from weeds ; and if the 

 feafon fliould prove dry, they muft be refreflied now 

 and then with water, which will greatly promote their 

 growth. When the plants are about two inches hio-h 

 they fnould be carefully tranfpUinted into a bed or bor- 

 der of frefli, light, undunged earth, obfervino- to fhade 

 them from the fun until they have taken root, as alfo 

 to refrefii them from the fun until they are well efta- 

 bliflied in this bed ; after which time they will re- 

 quire no farther care, but to keep them conftantly 

 clear from weeds till Michaelmas, when they are to 

 be removed into the places where they are dcficrned 

 to remain for good. 



When the plants are firft tranfplanted from the feed- 

 bed into the nurfery-bed, they fliould be planted 

 about fix inches afunder every way, which will be 

 fufficient room for them the firft feafon ; and this 

 will admit of the hoe to come between the plants 

 to deftroy the weeds, which is by much a better me- 

 thod than pulling out the weeds by hand, and is 

 much fooner performed. For as the hoe ftirs the 

 ground between the plants, it not only cuts down 

 the weeds which were up and vifible, but alfo de- 

 ftroys all thofe whofe feeds were fprouted, and would 

 have foon after appeared ; fo that one hoeing, if 

 well performed, and in dry weather, will more ef- 

 feftually deftroy the weeds, than two'hand-weedings 

 would do, were they performed ever fo carefully ; 



befide^i the ftirring the ground is of great fervice to 

 tlie plants. " 



"Kl Michaelmas, when the plants are tranfplanted for 

 good, they fhould be* carefully taken up with balls 

 of earth to their roots ; and they muft be planted in 

 the middle of the borders in the pleafure-garden, in 

 frefh light, earthV intermixing them with other hardy 

 plants of the fanie growth, where they will make a 

 pretty appearance when they are in flower, and will 

 continue three or four years ; and in fome poor ftony 

 foils I have known the roots live fix or feven years, 

 but thefe did not produce fo large fpikes of flowers, 

 as thofe v/hich were younger and more vigorous plants. 

 Therefore, as thefe plants do not continue many 

 years, it will be proper to raife a fupply of young 

 plants to fucceed them, for the old plants will pro-, 

 duce feeds plentifully, which are ripe the latter end 

 of Auguft or the beginning of September, when they 

 ftiould be gathered in dry weather, and kept in a. 



warm dry room till the time for fowing them.
