 10 to 60 mm. long, linear or narrowly lanceolate; pedicels reflexed in

1. Talinum paniculatum (Jacq.) Gaertn., Fruct. et Sem. 2: 219. 1791. 



Portulaca paniculata Jacq., Enum. PL Carib. 22. 1762. 



Greenlee County to Cochise, Santa Cruz, and Pima Counties, 3,500 

 to 5,500 feet, rich soil among rocks in partial shade, August to Sep- 

 tember. Florida to Arizona, south to tropical America. 



Easily distinguished from the other Arizona species of this genus by 

 its relatively tall leafy stems, broad flat leaf blades, and large open 

 panicle of small flowers. 



2. Talinum validulum Greene, Leaflets 2: 270. 1912. 



Coconino County, in the Tusayan (now the Kaibab) National 

 Forest (Hill in 1912, the type collection), and at Rattlesnake Tanks, 

 5,900 feet (Leiberg 5966). Known only from Arizona. 



3. Talinum parviflorum Nutt. ex Torr and Gray, Fl. North Amer. 



1: 197. 1838. 

 Showlow, Apache County (Peebles and Smith 13974), near Prescott, 

 Yavapai County (Peebles et al. 2695), 5,000 to 6,200 feet, yellow pine 

 forests. Minnesota and North Dakota to Arkansas, New Mexico, 

 and Arizona. 



4. Talinum gooddingii P. Wilson, North Amer. Fl. 21: 287. 1932.

 Known only from Arizona. 



The specimens from Nogales have shorter and stouter cusps of the 

 sepals than in the type collection. Traces of such appendages are 

 occasionally seen in specimens of T. parviflorum from farther east, and 

 the two species are not distinguishable by the shape of the capsule, 

 as indicated in the key in North American Flora.
