507. Northern Island, Colenso. Differs from P. deltoidea in the more oblong periautli and 
rounder softer leaves. 
2/1. TEMNOMA, Mitten (from the truncate mouth of the perianth). — 
To this are referred Jungermannia pulchella and quadrijida (p. 504), together 
with some other not New Zealand plants. 
2/2. CH ANDOBT ANTHUS, Mitten. — From the open plaited mouth 
of the perianth, includes Jungermannia squarrosa (p. 503) of New Zealand, 
and others. 
5. LOPHOCOLEA. — Characterized by its 3-gonous closed perianth. 
L. Colensoi (p. 509) has been found in fruit, and proves to be a Chiloscyphus. 
5/1. TRIGONANTHUS, Spruce, approaches Lophocolea, but the pe- 
rianth is different and the stipules usually wanting on the barren stems. The 
New Zealand species is J. dentata (p. 503). 
2/3. SOLENOSTOMA, Mitten, includes Jungermannia inundata (p. 
502), and rotata (p. 503). The perianth in this genus adheres to the base 
of the uppermost leaves. 
8. CHILOSCYPHUS.— Lophocolea Cplensoi, p. 509, should be 
transferred here ; it resembles C. coalilus, but is larger, more succulent, the 
dorsal angles of the leaves are more widely separate ; perianth short, cam- 
panulate ; lips toothed, not exserted beyond the leaves. 
11/1. TYLIMANTHUS, Mitten, here proposed for Gymnanthe saccata 
(excl. syn. Urmlleana ) (p. 520) and another, — the name Gymnantlie being 
too near Gymnanthes and Gymnanthus. 
11/2. ACROBOLBUS, Lelrn. and Lindb., includes Gymnanthe unguicu- 
lata and G. lophocoleoides (p. 519). (In description of unguiculata, for 
leaves obscurely 12-lobed read 2-lobed.) 
11/3. LETHOCOLEA, Mitten, consists of Gymnanthe Drummondii, 
p. 519. 
11/4. BALANTIOPSIS, Mitten, includes Gymnanthe, G. diplophylla 
(p. 519), and the following. 
3. B. erinaeea, Mitten. Lobes of the leaf free at the base, inferior 
broadly ovate, notched at the apex with 2 teeth, both margins ciliated ; 
superior lobe nearly orbicular, notched at the apex and ciliate. Stipule un- 
equally 6-partite ; lacinise toothed and ciliate. — Mitten. 
New Zealand, Lyall. 
11/5. MARSUPIDIUM, Mitten. — To this genus belong Gymnanthe 
setulosa (p. 519), and the true G. Urvilleana, which was confounded with 
G. saccata at p. 520. 
2. M. Kniglitii, Mitten. Stem short, simple, curved. Leaves largest 
towards the middle of the stem, patent or appressed, orbicular or subquadrate ; 
anterior margin entire, ending in a spine; apex subtruncate; posterior 
margin sparingly toothed. Sac oblong on a very short branch, to which it is
