LiNDLEYELLA 



This genus has been known as Lindlcya II.B.K. (1823). But 

 the name Lindlcya had been used twice before, viz., in 1 821-2 by 

 Kuntli* and by Nees.f The former is supposed to be a synonym 

 of Casearia Jacq. and the latter of Laplacca H.B.K.J; pubh'shed 

 the same year. Which of the two was first pubh'shed can scarcely 

 be decided, and Lindlcya Nees may replace Laplacca H.B.K. 

 Following the rule, ''Once a synonym, always a synonym," the 

 writer was forced to propose a new name. 



That the genus contains more than one species is evident. If 

 anyone compares the illustrations cited in the North American 

 Flora under L. nicspiloidcs with those in the Botanical Register 

 and the Fleurs des Serres, cited under A. Scliicdcana, he will see 

 that they can scarcely represent the same plant. Z. incspi'oides 

 has been described as a very variable plant, perhaps partly on 

 account of these very unlike illustrations. There are perhaps 

 more than two species included, but the author has no evidence 

 that proves the existence of more than two. All the specimens 

 found in the herbaria of the New York Botanical Garden, Harvard 

 University, and the United States National Museum, except one,, 

 agree fairly well with the original illustration in Humboldt, Bon- 

 pland & Kunth's Nova Genera et Species. The only exception 

 is Schiede's plant and this agrees fairly well with the illustrations, 

 in the Botanical Register and in the Fleurs des Serres. 



Vauquelinia 



When the author began the revision of this genus, he had two- 

 species at hand, which had been named V. corynibosa, but the 

 first glance at the original illustration of the latter showed him 

 that neither of the two could belong to it. One of these was- 

 referred to V. corymbosa by Torrey in the Botany of the Mexican. 

 Boundary Survey. This error was corrected by Watson, who- 

 renamed the plant V. Torreyi. The plant had been collected 

 earlier, however, during Emory's Reconnoissance and had beeni 

 described by Torrey as Spiraea californica. For this reason the-
