2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 98 



NYCTAGINACEAE 

 Boerhaavia tuberosa Lam. 111. Gen. 1 : 10. 1791. 



Charles Island (no. 120). This species is common in the Galapagos 

 Islands and occurs also in Peru. Records for B. scandens L. in the 

 Archipelago evidently apply to B. tuberosa. 2 



AIZOACEAE 

 Sesuvium edmonstonei Hook. f. Trans. Linn. Soc. 20: 221. 1847. 



Sulivan Bay, James Island (no. 106). Endemic to the Islands. 



CAESALPINIACEAE 



Emelista tora (L.) Britton & Rose, ex Britton & Wilson, Sci. Surv. Porto 

 Rico & Virgin Is. 5: 371. 1924. 

 Cassia tora L. Sp. PI. 376. 1753. 



Charles Island (no. 125). Common throughout the Tropics and 

 in warmer parts of temperate regions ; apparently not before reported 

 from the Galapagos Islands. 



Parkinsonia aculeata L. Sp. PI. 375. 1753. 



Charles Island (no. 114). A common tree of the American Tropics. 



PAPILIONACEAE 



Parosela parvifolia (Hook, f.) Macbr. Contr. Gray Herb. 65: 23. 1922. 

 Dalea parvifolia Hook. f. Trans. Linn. Soc. 20: 225. 1847. 



Charles Island (no. 112). Species not previously represented in the 

 National Herbarium. 



The writer has given 3 reasons for retaining for this genus the name 

 Parosela, in general use among American botanists. Dalea has been 

 proposed as a conserved name by the International Committee on 

 Nomenclature. 



Galactia velutina Benth. in Tayl. Ann. Nat. Hist. 3 : 437. 1839. 

 Galactia jussiaeana var. volubilis Benth. in Mart. Fl. Bras. 15 *: 143. 1859. 



Elizabeth Bay, Albemarle Island (no. 109). Also in northern and 

 eastern South America. In reports on the Galapagan flora this plant 

 is listed as G. jussiaeana var. volubilis, but special studies which the 

 writer has made of South American Papilionaceae indicate that it rep- 

 resents a species distinct from G. jussiaeana.
