Christ — Notes on Genera of Paniceac. II f. 185 



Raddia polypodioides (Triii.). 



Olyra polypodioides Trin. L835, Mem. Acad. Petersb. Ser. VT. 3 : 2 117. 

 "V spp. Bahiens." 



Raddia strictiflora (Fourn.). 



St re phi nut strictiflorum Fourn. 1876, Bull. Soc. Bot. Belg. 15 : 405. 

 "Arroyo Sellero ( Karw. [insky] n. 1473 in herb. Petropolitano)." 



Olyra strictiflora Hemsl. 1885, Biol. Cent. Am. Bot. 3:510; based on 

 the preceding. 



Raddia nana ( Doell). 



Olyra nana Doell 1877, in Mart. Fl. Bran. 2 : 2 :!2!>. "Ad Ega prov. do 

 alto amazonas (Martius)." The type is in the herbarium of the Botan- 

 isches Museum at Munich. 



Raddia concinna (Hook, f. ). 



Olyra concinna Hook f. 1896, Bot. Mag. Ill, 52 : t. 74(39. " 0. concinna 

 arrived at the Royal Gardens, Kew, in 189] * * * sent by Mr. C. 

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



Olyra sympodica Doell, 1877 in Mart. Fl. Bras. 2 : 2 322 probably belongs 

 in this group as suggested by Doell (op. cit. p. 329). It seems likely that 

 the " sympodium " he describes is not truly a sympodium but that the 

 culms simulate this habit by a twisting of the internodes, as not infre- 

 quently occurs in this genus and in Lithachne.
