 was lo titled by Dr. Linnxus, in honour of Dr. Col-

 raniVc, and has difcovercd fevcral new plants which 

 were not known before.

 l^his plant was brought from Maryland, where it 

 grows wild, as it alio does in many other parts of 

 North America, by the fides of ditches, and in low 

 moift ground, where it ufually rifes to the lieight of 

 four or five feet ; but in England it feldom |rowi 

 above three feet high, and unlcfs it be planted in a 

 moift warm fituation, or in dry weather is duly wa- 

 tered, it rarely flowers well -, therefore many people 

 keep the plants in large pots, for the more convenient 

 watering them, but thefe plants feldom

This hath a perennial root. The ftalks decay in the 

 autumn, and frefh fhoots come out in the fpring. 

 The ftalks are fquare, garniflied with heart-lliape'd 

 leaves, placed oppofite, which are fawed on their 

 edges. The flowxrs are produced at the extremity of 

 the ftalks in loofe fpikes ; thefe have long tubes, and

have been brought to fome of the curious botanic 

 gardens. It was fent me by Dr. Linnaeus, profeflbr 

 of botany at Upfal in Sweden. It is an annual plant, 

 whole branches trail on the ground ; they extend near 

 a foot from the root, and divide into many fmaller 

 branches, garniftied with fhort leaves, fitting clofe 

 to them; thefe are deeply crenated on their edges, 

 and have feveral longitudinal veins ; they are of a 

 glaucous colour, and come out without order. Tlie 

 flowers are produced at the wings of the leaves, 

 growing in fmall clufters; thefe have one funnel- 



This plant may be eafily propagated by parting the 

 roots in Oftober. Thefe roots fnould be planted at 

 three feet diftance, for they require much nourifh- 

 ment, otherwife they will not thrive. This plant 

 will live in the open ground, if it is planted in a ihel- 

 tered fituation.
