1. c, from Ternate; and C. silvestris Rumph. 1. c. 171, from Ceram. 

 These are entirely undeterminable from the material and data 

 now available, and their identity must await the results of field 

 work in the two islands mentioned. 



ABROMA Jacquin 

 ABROMA FASTUOSA Jacq. Hort. Vind". 3 (1776) 3, t. 1. 



Abroma (Ambroma) augusta Linn. f. Suppl. (1781) 341. 

 Gossypium daemonis Rumph. Herb. Amb. 4: 38, t. 1^. 



No representative of the genus Abroma occurs in our Amboina 

 collection, yet Gossypium daemonis Rumph. is manifestly an 

 Abroma. Linnaeus, in Stickman Herb. Amb. (1754) 15, Amoen. 

 Acad. 4 (1759) 126, erred in reducing it to his Hibiscus zeyla- 

 nicus. Roxburgh, Fl. Ind. ed. 2, 3 (1832) 156, seems to be 

 the first author to make the reduction to Abroma, by referring 

 it to Abroma augusta Linn. f. The form described by Rumphius 

 is manifestly what is currently named Abroma fastuosa R. Br.; 

 that is, the form with spiny branchlets. Abroma mollis DC, 

 Prodr. 1 (1824) 485, is described from specimens originating in 

 the Moluccas, and is unquestionably the same as the spiny form 

 currently named Abroma fastuosa R. Br. I have adopted the 

 oldest name, Abroma fastuosa Jacq., but if this smooth-stemmed 

 form be really specifically distinct from the form with the spiny 

 stems, some adjustment of the synonymy will be necessary. 



H ERITI ERA Dryander 

 H ERITI ERA LITTORAL IS Dryand. in Ait. Hort. Kew. 3 (1789) 546. 

 Atunus litorea Rumph. Herb. Amb. 3: 95, t. 63. 



This common and widely distributed strand plant is not rep- 

 resented in our Amboina collections. The reduction was first 

 suggested by Lamarck, Encycl. 4 (1797) 228, and has generally 

 been accepted by subsequent authors. Roxburgh, Fl. Ind. ed. 



2, 3 (1832) 142, erroneously reduced it to Heritiera minor Roxb., 

 and by others it has been referred to Heritiera fomes Ham. 

 It is, however, unquestionably Heritiera littoralis Dryand.
