102 CONTRIBUTIOTSTR FROM THE NATIONAL TIKRBARIUM, 



much longor than the loaves; pediceLs 1 to 1,5 mm, long; calyx bearin;^ yellow stiff 

 hair?; sepals linear, the lower mnch longer; banner brown, orbicular, jmbescent 

 without; pods pubescentj 2 cm. long; mature seeds nut seen. 



Type U. S* National Herbarium no. 40237, collected by Dr, E. Palmer near 

 Tequila, Jalisco, 1886 (no. 2fi9). Also collected near the same station by C. G. Prin- 

 gle, September 25, 1893 (no. 4597). 



This species was distributed as Rliynchmm phascololdes DC, from which it is 

 very distinct in foliage, pods, distribution, etc. This species is named for ]Miss Aiuia 

 Murray Vail, who ^^ Ih^st called attention to the fact that Doctor Palmer's }>lant had 

 been wrongly distributed. 



WITH 



The g'onus Odonia w;is first described by Bcrtoloni in 1822 jind 

 afterwards taken up by DeCandollc in 1825 and Sprcngol in 1827- 

 Bentham and Hooker, however, combined it with Galactia, where it 

 has since remained. Tt is true that many supposed species of Galactia 

 are congeneric with Odonia and this Is probably the one reason why 



the two genera have been combined. The true type of Galactia is the 

 large scarlet-flowered species from Jamaica long known as Galactia 

 pendida but now as Galactia galactia. It is very different from all our 



United States and Mexican species in its corolla. The Mexi(*an specdes 

 of Odonia will be as follows:
