[ii. p. 456.] BUCHNERA. 



In a revision (Proc. Am. Acad. xix. p. 93) of the North-American species of this 

 genus, Dr. Gray restores B. pilosa to specific rank, and excludes as well B. lithospermi- 

 foha, H. B. K., from the synonymy of B. elongata. He also refers Hartweg's 100 

 and Botteri's 583 and 794 to our B. mexicana; and he doubtfully adds B. disticha, 

 H. B. K., to the Mexican species (Ghiesbreght, 8260), with B. tinctoria, BertoU, for a 

 synonym. 



[ii. p. 456.] 32*. ALECTRA. 



Alectra, Thunb. Nov. Gen. p. 81 ; Benth. et Hook. Gen. Plant, ii. p. 966. 



About fourteen species, spread over Tropical Asia, Africa, and America.

 xviii. p. 131. 



Noeth Mexico, in the Sierra Madre south of Saltillo, Coahuila (Palmer, 2024), 

 without locality (Gregg). 



We had wrongly referred Palmer's specimens to G.grandiflora, Benth., which species 

 is not known to occur in Mexico.

 Acad, xviii. p. 133.

 xviii. p. 132. 



South Mexico, Guanajuato (Duges). 



[ii. p. 468.] CONOPHOLIS. 



Until it was too late we had overlooked the publication by Liebmann of two new 

 species of this genus ; and since the appearance of that part of our work containing 

 Conopholis, S. Watson, on the authority of an herbarium specimen named C. mexicana 

 by A. Gray, has published a new species for some at least of the Mexican specimens in 

 the Harvard herbarium. We must leave unanswered the question of the number of 

 species of Conopholis in Mexico ; but as Liebmann's descriptions were published in a 

 book that has been entirely overlooked in this country and America, and is very rare, 

 it will be useful to repeat them here.
