 planis ; coronee stamineae foliolis incrassatis, disco obovato concavo 

 angulo interno longiuscule acuminato, marginibus baud revolutis, dorso 

 eximie bicarinato. — Samoan, Tonga, and Feejee Islands. This may 

 be Forster's Asclepias voluhilis (non Linn.), from Tanna. It is the 

 Hoya Billardieri, no. 319, of Dr. Seemann's list ; but hardly that of 

 Decaisne. For the pieces of the stamineal crown are strikingly acu- 

 minate, instead of " angulo interiore obtuso." 



HoTA DiPTERA, Secmaun, no. 320, we have also from the Feejee 

 Islands, along with other indeterminable specimens equally without 

 flowers or fruit.

 Convolvulus ovalifolius, var. ? Hook. & Am. — Maui, Remy, no. 420. 



We have abundant ripe fruit and a few flower-buds. Remy's no.

 covering a hard seed-coat. If Brown has rightly stated the difference
