Island. It differs from typical P. crassifolia in having a funnelform co- 

 rolla as long as or longer than wide, rather than a rotate corolla. 



Physalis GLABRA Bcnth., Bot. Voy. Sulph. 39. 1844. 



Punta Frailes, February 16, Dawson 1128. 



Known only from the Cape District of Baja California. 



Physalis pubescens L., Sp. PI. 183. 1753. 



Canyon above Puerto Escondido, March 13, Rempel 157; April 22, 

 Gentry 3764, riparian in canyon bottom. 



A mesophytic to hydrophytic annual with pale yellow flowers, purple 

 stamens, and pubescent viscid herbage, widely distributed across southern 

 United States and southward in Mexico ; Galapagos Islands. 



Physalis purpurea Wiggins, Cont. Dud. Herb. 3;74. 1940. 



San Carlos Bay, Sonora, February 8, Dawson 1063. 



Known only from the vicinity of Guaymas, Sonora. This perennial 

 Physalis with its bright purple corolla and rather open habit with remote 

 leaves is not easily confused with any other members of the genus in the 

 gulf area. Its apparent very limited distribution, which kept it from 

 being discovered so long, probably marks it as an endemic of the coastal 

 mountains near Guaymas, and which for a period in the Tertiary may 

 have been insular. 



SoLANUM HiNDSiANUM Bcnth., Bot. Voy. Sulph. 39. 1844. 



Tiburon Island, January 25, Dawson 1011. San Carlos Bay, Sonora, 

 February 8, Dawson 1052, Punta Frailes, Baja California, February 16, 

 Dawson 1142. San Jose del Cabo, February 17, Dawson 1192. 



Baja California and Sonora; type from Magdalena Bay. This plant 

 is a low openly branched shrub rather closely related to S. elaeagnifolium, 

 but in the field is at once distinguished by its larger size and larger 

 corollas. It becomes abundant locally in the southern part of the gulf 

 region, but is infrequent in the northern part. 



Scrophulariaceae 



Antirrhinum cyathiferum Benth., Bot. Voy. Sulph. 40. 1844. 



Near Guaymas, Sonora, February 9, Dawson 1084. 



Southwestern Arizona, Sonora, and Baja California; type from Mag- 

 dalena Bay. Guaymas appears to be about the southern limit for the 

 species on the mainland.
