 If, however, the American rule, " Once a synonym always a 

 synonym," be followed, the name piirpiirascens must entirely dis- 

 appear, and A. amplexicauUs Smith must be retained. The plants 

 will then stand : —

Glycine elliptica. 



" This Glycine, received from Kalm, is referred in the Linnean 

 herbarium to comosa, which species Linnaeus took up entirely from 

 Gronovius, without having seen it, and which indeed we believe, on 

 the authority of original specimens in the Gronovian herbarium, to 

 be by no means distinct from G, monoica of Linn^us (bracteata of Sp. 

 PI. ed. i.). As, however, all that Linnaeus has said of this species 

 refers to the plant of Gronovius, and even the short observation in 

 Syst. Veg. is taken from the Flora Virginica, and not from Kalm's 

 specimen, we have thought it best to give a new name to that 

 specimen and our figure, and to define it foliis ternatis : foliis 

 cUipticis siibtus pilosis glands, racemis axillaribus, leguminibus line- 

 aribus.'' (Vol. i. t. xxi. p. 41). 



This plant — I think in consequence of a misunderstanding of 

 Smith's meaning — has been generally treated (e. g. in S. Watson's 

 Bibliographical hidex and in the Index Kewensis) as a synonym of 

 Amphicarycea monoica. A mere glance at the figure, however, 

 shows that Smith had a very different plant in view ; and Miss 

 Vail, who has examined with me Smith's type in the Linnean 

 Herbarium, agrees in referring it to Galactia glabella Mich. 



SpERMACOCE HYSSOPIFOLIA. 



** The plant here delineated appears to be a new species of 

 Spermacoce, which is preserved, without a name, in the Linnean 

 Herbarium. Mr. Abbot calls it wild thyme, probably from its 

 habit, for it has no other affinity to any plant of the thyme kind. 

 The root is strong and woody, the stem shrubby, and somewhat 

 diffuse. It may be characterized as follows : — 



" Spermacoce HYSSOPiFOLiA,/oZm lijieari-lanceolatis revolutis ynargine 

 scahris, verticillis paucifloris.'" (Vol. i. t. xxxviii. p. 75.) 



This name (which is in the hidex Kewensis) was not taken up in 

 the Frodromus; a fuller description of the plant is given in Eees' 

 Cyclopmlia. The plant is in the Linnean Herbarium, but I have 

 not been able to compare it with other species. 



Quercus lobulata Soland. MSS.

 one, and may be characterised foliis subtus pubescentibus duplicato
