          Cambridge, Saturday afternoon 


 My Dear Friend 


 Yours of the 23rd has just come to hand. 
 I begin to make notes of reply. Thanks for the nos. [numbers] 
 of Fremont's plants. 


 As to no. 86, of 1844 (which is Collinsia bartsiaefolia)
 I find a little discrepancy between the date (March 25th) &
 the locality on the Rio de las Americanas. See the Report,
 p. 248, Senate Edition. But it is little matter. 


 Friday Evening. 


 The little Texan & Coulter plant which bothered
 us so, has a plicate aestivation to the [corolla?], 
 and is the Salpiglossis? Prostrata, Hook. & Arn. bot. 
 Beechey [Hooker and Arnott's Botany of Captain Beechey's voyage]. It is however excluded from that genus,
 and left in true Solanaceae!
