sissimis integerrimis." — Mountains of Kauai. This was doubtfully 

 referred by Gray to D. Delessertiana, Gray, 1. c., which is Rollandia 

 Dehssertiana, Gaud. Bot. Bonite, t. 75, which again appears to be iden- 

 tical with R. lanceolata, Gaud. I have httle doubt that it is a variety 

 of D. coriacea, but only some leaves have been collected.

 pubescentibus ; racemis plurifloris petiolum gracilem baud superanti- 

 bus ; calycis limbo minuto vel fere obsoleto ; corolla gracili subpollicari

 petiolatis ; pedunculis paucifloris petiolo brevioribus ; lobis calycis 

 lanceolatis ovario multo brevioribus. — Mountains above Waimea, 

 Kauai. — A large branching shrub, 20 feet high, hirsute with short 

 rusty hairs. Leaves 7 to 10 inches long, 2 to 3 wide. Petioles about

 vioribus ; pedicellis filiformibus nudis, floribus racemosis; calycis lobis 

 lanceolatis puberulis ovario dimidio brevioribus; corolla (12-16 lin. 

 longa) glabrata ; columna staminea hirtella; seminum testa l^evissima
