NicoTiANA Greeneanum Rosc, C.N.H. 1:18. 1890. 



Agua Verde Bay, March 10, Rempel 127, wash. 



Known previously only from Cedros Island and the adjacent western 

 part of the peninsula, this appears to be the first record of the plant from 

 the gulf side of the peninsula. The annual habit, nonclasping and non- 

 auriculate leaves with ovate to lanceolate blades, the small corolla with 

 very narrow limb (3 mm wide in the dried specimen), and the dull 

 light brown muriculate seeds relate it pretty definitely to Rose's plant. 



NicoTiANA TRiGONOPHYLLA Dunal in DC, Prodr. 131:562. 1852. 



San Carlos Bay, Sonora, February 8, Dawson 1023, 1059, Near 

 Guaymas, February 9, Dawson 1078. Tortuga Island, March 17, 

 Rempel 217. 



Mostly in the coarse alluvial soils in arroyos and valleys in Desert 

 Shrub and Thorn Forest from Texas to California and south to Nayarit. 

 This is a common member of the tobacco genus in the arid gulf region. 

 It appears to be perennial in the lower latitudes of its range, as shown 

 by the woody base of Dawson 1023. Another sheet, Dawson 1078, repre- 

 sents a young plant in its first season of spring flower, indicating it as 

 having germinated during the preceding early fall or late summer rains.
