The glabrous species of this group are represented by two 

 widely distributed species, T. gracilentum T. & G. and T. cilio- 

 Icttinn Benth. The original description of the former by Tor- 

 re}- and Gray seems to be good, but the plant is quite variable 

 as to the size of the flowers and the comparative distance that 

 the vexillum exceeds the calyx teeth. We find also a consider- 

 able variation in the breadth and length of the calyx teeth. The 

 vexillum, wings and keel, are frequently tipped with cream- 

 white, the remainder of the flower being some shade of purple, 

 usually bright. The reflexed character of the flowers in the 

 head at maturity is omitted from the original description. The 

 legume is more frequently two than one-seeded.
