CONTRIBUTION TO THE HISTORY OF AROIDEOLOGY. 205 
“ Tapanava. Kitsjil " (nomen Amboinense) (Amb. v. p. 490, t. 184, f. 
1,2, 3). Linnzus, availing himself of the description given by Bur- 
mann (Thes. Zeyl. 197 ; 1737), founded, ten years later, the genus 
crenata, cordata, pinnata, palmata, and scandens. Of these, however, 
only the species first made known, and placed last in the ‘ Species 
Plantarum’ (P. scandens), is a representative of the genus Pothos. All 
the other species are representatives of other genera. Thus P. lanceo- 
lata, crenata, cordata, and palmaía are the first-known species of 
Anthurium ; whilst P. pinnata is the earliest-known Rhaphidophora: 
Three genuine species of Pothos, though figured and described by 
Rumphius, were by an oversight not inserted in the ‘Species Plan- 
. tarum, ed. 2, viz. P. tener (‘ Appendix arborum prima,’ Amb. v. t. 
181, f. 1), P. macrostachyus (‘ Ap. arborum altera, Amb. v. t. 181, F 
2), and P. Rumphii (* A. porcelianica, Amb. v. t. 182, f. 1), one of 
the three species still amongst the least-known AÆroideæ. “ Appendix 
laciniata " (Amb. v. p. 489, t. 183, f. 2) is a synonym of Rhaphido- 
phora pinnata “ Elletadi Maravara”’ (Rheede, xii. t. 20, 31; 1703), a 
second species of Rhaphidophora (R. pertusa). Unnoticed were “ Ap- 
pendix Cuscuaria," of Rumphius (Amp. v. t. 183, f. 1); i.e. what now 
is termed Cuscuaria marantifolia. Plumier’s generic names for the 
above-named Anthuriums were Arum, Dracontium, Dracunculus. 
There is hardly anything to remark about Orontium, the fifth genus 
of 4roideg of the second edition of the ‘ Species Plantarum,’ which, 
although discovered by Banister and described by Ray as early as 1704, 
was only admitted in 1756 in the ‘ Ameenitates,’ vol. iii. Up to this 
time we know only one species. 
Nor is there much to say respecting Acorus, the sixth and last genus 
of Linneeus’s work. The generic character in the second edition of 
the ‘Genera Plantarum,’ with a few unimportant alterations, still holds 
good. Theophrastus, and even Hippocrates, called it KdAapos ; the 
H 
Linnzeus described only one species (4. Calamus), but distinguished the 
plant common with us from that of Indian Asia. In recent times it 
has been ascertained that several species occur in India and the adja- 
cent countries, and as the species enumerated by Rumphius (Amb. v. 
P.178,t. 72) and Rheede (Mal. xi. p. 99, t. 60; 1692) are not yet
