Raddia concinna (Hook, J.). 



Olyra concinna Hook f. 1896, Bot. Mag. Ill, 52 : t. 7469. " 0. concinna, 

 arrived at the Royal Gardens, Kew, in 1891 * * * sent by Mr. C. 

 Winkle, from San Jose in Costa Rica. It flowered in January, 1895." 

 Kfi^f" ^ Olyra sympodica Doell, 1877 in Mart. Fl. Bras. 2 : 2 322. probably belongs 

 Z / (/-*v<' / in this group as suggested by Doell (op. cit. p. 329). It seems likely that 

 il "t^rf^ ^ ie " s y m P 0Cuum " ne describes is not truly a sympodium but that the 

 (y \\r culms simulate this habit by a twisting of the internodes, as not infre- 

 quently occurs in this genus and in Lithachne.
