Mr. Lambert's Observations on the Zizania aquatica. 265 
Canada; and the seeds, which are as large as oats, and perhaps as 
nutritive, are used by the Indians for food ; as may be seen in Carver's 
Travels in America, and also in Kalm's Travels, vol. 3. p. 32 and 54. 
This species has been so fully described already by Linnaeus in 
his Mantissa, that any further description would be superfluous : 
but as the figures which have been hitherto given of it are very 
imperfect, I beg leave to present the Society with a plate engraved 
from a drawing made from a plant growing at Spring-Grove. 
Dr. Smith, on the authority of the Linnaean Herbarium, informs 
me that this is certainly what Linnaeus meant by Zizania palustris 
in his Mantissa, although it is what he had previously described 
in both editions of his Species Plantarum under the name of 
Z. aquatica, as the original specimen shows. It seems however that 
he latterly intended Sloane's plant, Hist, of Jamaica, tab. 67. to 
remain as the aquatica, conceiving that, on account of its great . 
spreading panicle, to be a different plant. Linnaeus notes in his 
manuscript that Z. terrestris of Ilort. Malab. v. 12. t. 60. should 
be examined, in order to be distinguished from this in the specific 
character. He further remarks, that the above plant, Zizania 
palustris, which he had in his garden, was well figured in a dis- 
sertation de Alimentis farinaceis, published at Leyden in 1760 by 
J. Scheuchzer. Probably Browne's synonym belongs rather to 
Sloane's plant.
