5S FRULLANIA. [ DIASTALOBA 
rotunda ad 4 acute bifida, segmentis acutis. Flores dioici. Bractez 
bijuge foliis sat majores, lobo elongato obovato-ligulato, lobulo angustiore, 
omnibus lobis apice ineurvo cuspidatis; bracteola angusta profunde 
bifida, segmentis rectis subulatis acuminatis, hinc connata. Perianthia 
magna pyriformia, basi attenuata, compressula alte 5-carinata, facie antica 
lata depressa. 
Obs. The perianth seems to have become 5-angled (from 3-angled) by 
the duplication of the lateral keels, for all five keels belong to the convex. 
postical face ; while the broad, plane, or depressed antical face is entirely 
ecarinate. 
Fr. myosota is referred by Mitten, in Hooker’s Handbook of the New 
Zealand Flora, to Fr. ptychantha Mont. The latter is, however, described 
by himself, and by the authors of the ‘Syn. Hepat.’ to have obovato- 
cuneate leaves.and a 9-plicate perianth, and must therefore be distinct 
from the “ Fr. myosota” I had trom Taylor himself. 
Fr. pentapleura H. f. et T. (Handb. Fl. N. Z. 537) might seem, from the 
name, to be the same as our Fr, myosota, but is in reality far removed by 
the semi-orbicular leaf-lobules.

Gracillima rufeseens, tenui strato arcte repens. Caules pollicares laxe 
pinnati et subbipinnati, ramis brevibus, raro superne microphyllis. 
Folia pellucida subimbricata patula decurvula oblique ovata abrupte sub- 
acuta vel brevissime acuminulata, basi antica dilatata caulem haud 
transeuntia ; lobulus ad } lobi altitudinis adstans obliquus saccatus

lobulum et caulem plerumque interjecto ; cellule parvee, pariete

esque coloratee. 
Foliola plus duplo breviora, caule vix latiora, lanceolata vel rectangulari- 
oblonga, fere plana, ad 4 acute bifida, segmentis acutis. 
Flores monoici : 2 incaule ramisque terminales. Bracteee 3-jugee sensim

Andrcecia ramulo brevi plerumque constantia. 
Obs. Ir. subtilissima Syn. Hep. eadem species videretur, descripta est

distantibus,” quum in nostra folia basi vix cordata, lobulique etiamsi 
obliqui nunquam horizontales. Quoad involucrum serratum ete. sat
