lateralibus innovantes, l-rhizæ. Inflorescentiz ex iisdem rimis lateralibus oriundæ, 3-floræ, spatha 
tenui membranacea fulte. Fl. g 2, l-andri; anthera profunde 2-loba, 4-locularis, rimis 2 dehiscens.

viter convexe, crassiusculz, sessiles, apice obtusiuscule; ovulum et semen erectum, hemianatropum. 
—Nomen vernac, Vitiense, * Kala."— Common in stagnant pools of Viti Levu (Seemann! n. 657). 
Also collected in New Zealand, Tasmania, New Holland, and most other parts of the world. 
2. L. melanorrhiza, (sp. nov.) F. Muell. et Kurz in Seem. Journ. 1867, p. 115; frondes 
convexiuscule (texturg L. polyrrhize) oblong: v. subrotund, subtus spongiosz, 1—2-rhizze, radiculis 
nigrescentibus v. brunneis.—Nomen vernac. Vitiense, “ Kala."—Common in stagnant water of Viti 
Levu (Seemann! n. 656). Also found in Western Australia. 
I should add that Dr. Hegelmaier a few years ago communicated the name and description of this spe- _ 
cies to me, which he also regarded as new; but during my absence from Europe, Mr. Kurz published his 
paper on Australian Lemnace@ in my ‘ Journal of Botany,’ and thus forestalled Dr. Hegelmaier, —the editor 
for the time being not being aware that I had previously received Dr. Hegelmaier's name and description. 
Orvo XCVI. SCITAMINEJZE. 
Besides the genera represented in Viti, there are found in tropical Polynesia Phrynium, with one species, 
viz. P. dichotomum, Roxb. (Thalia canneformis, Forst. Prodr. n. 3, et ic. [ined.], t. 1), from Malicolo, 
New Hebrides, and thence extending to the East Indies (Roxburgh !) and the Archipelago (Staunton ! 
Buchanan !) ; and Hedychium, with one undescribed species, collected (in fruit only) in the moùntains of 
New Caledonia (Deplanche! n. 120). |

A great many different kinds of Musa were found cultivated in different parts of tropical Polynesia 
when Europeans first became familiar with them. In Tahiti alone Banks and Solander saw twenty-eight, 
which Solander (Prim. Fl. Ins. Pacif. [ined.] p. 344) enumerates under two different headings, those named 
collectively “ Fei” by the natives (including five kinds), and those named collectively * Maya " by the natives
