TETRAPLASANDRA A. Gray. 

 (Triplasandra Seem.) 



Calyx border undulate or denticulate, petals 5 to 8, valvate in the bud. Stamens as 

 many as petals or 2 to 3 times or even 6 times as many, arranged in 1 or 4 series, with 

 rather thick filaments and ovate or lanceolate anthers. Ovary quite inferior, ovate, 13-7-5-2 

 eelled. The stigmas on a short stylopod or subsessile; drupes globose to ovate-elongate 

 or cylindrical, with a somewhat fleshy covering. Pyrenae chartaceous, crustaeeous or 

 coriaceous, compressed. Seeds often ribbed or furrowed. Unarmed glabrous or tomentose 

 trees or shrubs with a glutinous sap. Leaves large, alternate impari-pinnate, with 5 to 13 

 entire leaflets; petiolule of the terminal leaflet usually articulate. Stipules wanting or 

 rudimentary. Inflorescence a racemose umbellate panicle or a simple or compound umbel; 

 bracts caducous, small or larger; peduncles not articulate, often very thick. 



The genus Tetraplasandra derives its name from the Greek TerpaTrAastos 

 (tetraplasios), fourfold, and avhpa (andra), stamens, having four times as many 

 stamens as petals. It consists of possibly 12 species, two of which are not found 

 in the Hawaiian Islands; T. paucidens Miq. occurs in New Guinea, while T. 

 Koerdersii Harms is found in Celebes. Of Hawaiian species, only two were de- 

 scribed originally, T. Jiawaiiensis A. Gray and T. Waimeae Wawra. All the 

 species of Triplasandra (established by Seeman) have been merged into Tetra- 

 plasandra by H. Harms. The writer has since added two new species : T. 

 Lanaiensis and T. Waialealae.
