262 FLORA VITIENSIS. 
Varies with glabrous and pubescent leaves. 
3. P. Macgillivrayi, Casim. DC. mss. (Tab. LXXV.); foliis ovatis acuminatis basi rotundatis 
cordatisve 5-9-nerviis supra glabris subtus reticulatis pubescentibus v. glabris, petiolis ad medium 
anguste membranaceo-alatis; amentis 9 elongatis solitariis. —Macropiper puberulum, G. Bentham in 
Hook. Lond. Journ. of Bot. 1843, p. 235 ; Miquel, Syst. Pip. p. 221. Nomen vernac. Vitiense, *Yago- 
yagona.” In woods, Viti Levu, Taviuni, and Kadavu (Seemann! n. 567; Barclay!). Also collected 
in the Tongan (Capt. Cook! Nelson! Barclay! Home!) and the Society Islands (Barelay !). 
There are two varieties of this species; one, confined to Viti, has the leaves pubescent, below; the 
other, found in Tonga and Tahiti, has the leaves glabrous on both sides. 
This plant is not used for any purpose; but in the belief of the people of Viti Levu it is sacred to the 
Veli (spirits of the woods),—in fact, their Kawa plant, which mortals cannot destroy or injure without 
exposing themselves to the danger of being severely punished by them.

*N. 569 of your Viti Collection (writes M. Casimir De Candolle) is a new species described in my 
manuscript under the name of P. insectifugum. It is evidently related to P. methysticum, Forst. (M. 
methysticum, Miq.), though differing from that species by the number of its stamens as well as by its 
nervation. P. Siriboa, Forst., to which you provisionally referred it, is the same as a Piper collected by 
Vieillard in New Caledonia, and which I describe under the name of Austro-Caledonicum.”
