FLOWERING PLANTS AND FERNS OF ARIZONA 869 



1. Lobelia fenestralis Cav., Icon. PL 6: 8. 1801. 



Chiricahua and Huachuca Mountains (Cochise County), near 

 Patagonia (Santa Cruz County), also a collection by Lemmon labeled 

 as from Oak Creek (Coconino County), 5,000 to 6,000 feet, meadows 

 and swales, August to November. Western Texas to Arizona and 

 southward to Oaxaca. 



2. Lobelia anatina Wimmer, Repert. Spec. Novarum Regni Veg. 



19: 385. 1924. 



Apache County to Coconino County, south to the mountains of 

 Cochise and Pima Counties, 5,600 to 8,600 feet, meadows, marshy 

 places, and stream banks. July to October. Southern New Mexico 

 and Arizona, and southward to Durango. 



A species quite distinct from L. gruina Cav., to winch most of the 

 United States material has previously been referred. 



3. Lobelia laxiflora H. B. K., Nov. Gen. et Sp. 3: 311. 1819. 

 Sycamore Canyon, near Ruby, Santa Cruz County, about 4,000 



feet (Goodding in 1936) , the only known locality in the State. Southern 

 Arizona and throughout most of Mexico and Central America. 



A polymorphic species. Many so-called species have been segre- 

 gated from it, but the better course appears to be to regard them all as 

 varieties of the original L. laxiflora , the typical form of which is found 

 in the region of Vera Cruz and southward. The plant of Arizona, at 

 least for the present, is best referred to var. angustijolia A. DC. 



4. Lobelia cardinalis L., Sp. PI. 930. 1753. 



Throughout most of the State, 4,000 to 7.000 feet, frequent in moist 

 soil, especially along streams, July to October. Widely distributed 

 in the United States, Mexico, and Central America. 



Cardinalflower. Represented in Arizona by subsp. graminea (Lam.) 

 McVaugh. Plants of this subspecies have previously been reported 

 as L. splendens WiUd. or L. julgens Willd. 



5. PORTERELLA 



Plant annual, diffuse, weak-stemmed; leaves lanceolate to linear, 

 entire or essentially so, the lower leaves often submersed and early
