RUMPHIUS'S HERBARIUM AMBOINENSE 



Not represented in our Amboina collections. Loureiro quotes 



Gnemon funicularis Rumph. as a synonym of Abutua indica Lour, 

 in the original description of that species. Louriero's type, 

 in the herbarium of the British Museum, is a leaf specimen, 

 and according to Doctor Rendie, who has examined it for me, is 

 apparently the same as Gnetum funiculare Blume. Roxburgh, 

 Hort. Beng. (1814) 66, based his Gnetum scandens on "H. M. 

 7. t. 22; H. A. 5. t. 7, 8," i. e. the first reference to Rheede 

 Hortus Malabaricus, and the second to Rumphius Herbarium 

 Amboinense ; I believe that the species should be typified by the 

 first reference. However, "Ula. Rheed. mal. 7. p. 41. t. 22" 

 is the whole basis of Thoa edulis Willd. Sp. PI. 4 (1805) 477, 

 so that Gnetum scandens Roxb. becomes a synonym of Gnetum 

 edule (Willd.) Blume, together with Gnetum ula Brongn. The 

 plant that Blume actually described as Gnetum edule seems 

 not to be the same as the Indian Thoa edulis Willd., but the 

 name must go with the Indian plant. It is by no means clear 

 that this continental form, which appears in modern literature 

 as Gnetum scandens Roxb., is specifically distinct from the 

 Malayan Gnetum indicum (Lour.) Merr., but at any rate, 

 Loureiro's specific name is much older than any of the others.

Funis gnemoniformls Rumph. Herb. Amb. 5: 12, t. 8. 



Not represented in our Amboina collections. Gnetum gne- 

 monoides Brongn. was based wholly on the Rumphian figure 

 and description of Funis gnemoniformis. Blume, Fam. Nov. 

 (1834) 31, Ann. Sci. Nat. II 2 (1834) 106, reduced Funis 

 gnemoniforw.is Rumph. to Gnetum edule Blume, a species based 

 on Thoa edulis Willd. and differing remarkably from Rumphius's 

 species, as described, in its fruit characters. Gnetum rumphia- 

 num Becc. was based on specimens from New Guinea, with 

 the addition of a reference to Funis gnemoniformis Rumph. 

 It has seeds 5 to 5.5 cm long, in entire agreement with 

 Rumphius's description of the fruits of Funis gnemoniformis 

 as "tres digitos transversales longi." Gnetum verrucosum 

 Karst. was described from specimens originating in Buru, with 

 fruits 4.5 cm in length, and I have no hesitation in reducing it to 

 Gnetum gnemonoides Brongn.
