glabree, radice tuberosa subglobosa v. conica; foliis omnibus radicalibus petiolatis palmatis, palmato- 
bi-tripinnatifidis v. indivisis, venosis, scapo radicali indiviso, umbella terminali simplici, involucro

The genus was confounded with Amorphophallus, not only by Rumphius, but also by Solander and 
Forster.

Viti (Seemann! n. 633, 908; Barclay!). Also collected in the Society (Banks and Solander! 
Forster! Barclay!), Tongan (Herb. Hook.), and Samoan Islands (Sir E. Home!), and Straits of 
Sunda (Staunton !). 
G. Forster quotes Rumphius’s Tacca sativa (which is identical with Amorphophallus campanulatus, 
Blume) aud T. sylvatica (which has not yet been identified) as synonyms of his T. pinnatifida ; and Solander 
also refers erroneously Rheede's and Rumphius’s plates to his species. It may be useful to add here 
Solander's description of this species :— 
“Cuaitma (Xaurys, comatus, frondosus, Ic.). Cal. perianthium ovatum hexaphyllum, foliolis ovatis, 
apice conniventibus, tribus exterioribus angustioribus. Cor. petala sex, calyce minora, pileiformi cucullata, 
emarginata: unguibus calycis fundo adnatis. Stam. filamenta nulla. Anthere sex, oblongz, cucullo intus 
adnate, apice deorsum spectantes. Pist. germen inferum, turbinatum, triquetrum. Stylus brevis, erectus. 
Stigma orbieulatum, stellatum, radiis obtusiuseulis, supra convexis. Per. bacca? ovato-globosa, calyci 
marcescenti coronata, sex-carinata, unilocularis. Sem. numerosa, ovalia, compressa, sulcata, involuta sub- 
stantia fungosa singulo semini propria distincta, polyedra.

colarum Oceani Pacifici. Hab. in Tahiti, Huahine, Raiatea, Tahaa, in collibus et locis montosis. Radix 
tuberosa, subrotunda: substantia alba. Folia petiolata, ad basin usque sinuato-tripartita, glabra, rugosa, 
late viridia, pedalia et sesquipedalia. Zobi laterales bipartiti, inzequaliter bipinnatifidi seu lobato-sinuati: 
lobulis ovato-lanceolatis, acutis, integris, bi- et triuncialibus: sinubus latissimis. Lobus intermedius 
eodem modo lobato-sinuatis, non vero bipartitus. -Petioli omnes radicales, pedales et bipedales, teretes, 
mutici, glabri, obsolete striati, herbacei, fistulosi, prope radicem nodo oblongo tumido instructi, pallide 
virides. Seapus herbaceus, fistulosus, bipedalis vel brevior, erectus, strictus, glaber, muticus, inferne levis, 
erassitie digiti minimi, superne angustiores, striati. Umbella simplex, multiflora, comosa, involucro folioso 
et bracteis numerosis crinita. —Zavolucrum polyphyllum. Foliola 6-10, per paria opposita, ovata, acu- 
minata, glabra, interdum extus incisa; externa e connata, interiora basi in ungues breves attenuata 
(2-3 unc. longa, 1i lata). Bractee numerosissime, filiformes, receptaculo inter pedunculos inserta, 
illisque quadruplo longiores; sspe 9- vel 10-unciales, penna passerina graciliores, undique divaricatz, a 
basi ad medium virides, extus purpurascentes. Pedunculi numerosi (10-40), bracteis tamen pauciores, 
teretes, filiformes, glabri, crassitie penne passerinsz, inter bracteas et involucra reflexi (unde flores pen- 
duli) uniflori, unciales et sesquiunciales. Calyx hexaphyllus, ovatus, persistens, circiter semiuncialis. 
-Foliola erecta, apice conniventia, obsolete immarginata; tria interiora ovata, tria exteriora angustiora sed 
paulo longiora; marginibus purpurascentibus. Petala sex, calycis fundo inserta illoque multo minora: 
lamine albæ, pileiformi-cucullate, intus profunde emarginate; sinubus denticulo parvo bifido instructis. 
* Tacea Parkeri (sp. nov.), Seem. ; foliis ovato-oblongis acuminatis in petiolum angustatis integerri- 
mis; involucro 4-phyllo, phyllis valde disparibus et heteromorphis 2 majoribus spathulato-ovatis acumi- 
natis, 2 minoribus sessilibus ovato-acuminatis; stigmata 3, biloba; capsula 1-locularis, loculis oo-spermis ; 
seminibus angulatis striatis.— British Guiana (Parker! Al n. 251). The larger involucral leaves 
twice or thrice the length of the two smaller ones. Possibly the specimens distributed by Dr. Spruce 
under x 3762, and provisionally named T. lanceolata by Bentham, may be merely young plants of my 
T. Parkeri. |
