ON THE NATURAL ORDER TACCACEA; WITH 
DESCRIPTION OF A NEW GENUS. 
By Henry Fuercuer Hance, Ph.D., F.L.S., &e. 
Tue small order of Taccacee ne consisted hitherto of but two 
genera, mintaiding about a dozen or rather more beer distributed 
throughout the sre beeps reigioil of India, the Malayan arehi- 
pelago, the Philippine ae , Polynesia, MaAaieaacae: and 
wana. Its relationship s been diversely interpr reted. Tacca 
was placed by A. L. de Jussieu, together with Hypowis, Pontederia 
Polianthes, and ‘Alstr emeria, amongst the ‘ genera Narcissis non 
omnino affinia,”’ of the Precise position of which he felt no doubt.* 
obert Brown remarked—* Inter Aroideas et Aristolochias locanda 
sit Tacca, illarum nonnullis foliis peculiaribus similis, nec seminum 
germinatione multum diversa ; his tamen floris et pericarpil 
structura propius accedens” +; and a similar view was taken by 
Blume. The elder Deichenbevl located Tacca in his family 
Aroidee, associating with it Acorus, Orontium, Peliosanthee, ght 
spermea, and Tupistree, as W . as Nepenthes, Sarracenia, — 
later peri 
cenia to Cistinee. @.§ Rroebee: vane it as a eae shh of his 
ivision n Asarinea, in 
his class Aristolochiea, and Saururea in that of Leaping || Lindley, . 
in his ‘ Nixus Plantarum’ (1883), placed it next to Burmanniacee, 
at the = of his ee in the epigynous cohort of Endogens, 
and touching Irideew in Iviales; but in his latest work re con 
sidered the true relation to be with Araceae, or at least with ike 
classed in his cohort Stegocarper hexandre, betw 
Hypowidea ;** whilst aaat though he ‘joubtfully enumerated
