Dr. S M I th'i Remarks onfome Foreign Species of Orobaticbe. 171 



The O. minor is the only one I have ever met with growing in 

 fuch fituations, or in fuch abundance as to be deemed a weed ; and 

 it attaches itfelf, as Hallcr obferves, to the roots of Diadelphous 

 plants, particularly clover. Gmeliti in his Flora Sibirica mentions 

 feveral varieties of what he took for O. major-, but it is notpoflible 

 to determine what they really are. 



/SHaller has recorded as a variety of his 295,/a Swifs Orobanche % of 

 which a drawing had been fent him, " with a very denfe conical 

 fpike, a very (hoit flower, and ffyle, projecting confiderably out of it," 

 which, he adds, " is fo remarkable as to deferve being reckoned a 

 fpecies, provided more fpecimens could be discovered" This fame 

 plant is to be found in the Linnsean herbarium, gathered in eaftern 

 Pomerania by a Mr. Brunnemann, and very well preferred. If a 

 variety of any thing, it muff be O. caryopbyUacca, with which the 

 iramina precifely agree; nor does it differ from the ether fpecimens 

 in my poneffion, except in being more luxuriant, with a greater 

 number of nowers in a younger, and therefore conical, fpike, and 

 in the corolla and ftamina being not half fo long as ufual, while the 

 ftyle protrudes confiderably. The germen is fmooth ; ffyle flightly 

 pubefcent, incurved, with a dark-coloured ftigma; bracfese, calyx, 

 and divifions of the corolla exactly as in the fpecies to which I have 

 ventured to refer it. 



I have only to obferve farther, that the Qrobanchecaryophyllacea 

 agrees very nearly with O. major in habit and fize, as well as the 

 appearance of its nowers ; but differs from the litter in having the 

 three fegments of the lower lip obtnfe, and much more fringed and 

 curled. The germen alfo is entirely fmooth, which in O. major is 

 hairy in the upper part, and the ftyle is much lefs downy than in 

 that fpecies. The moft finking mark, however, of O. caryophyllacea 

 confiffs in the lower part of the flamina, on the mfide, being thickly
