192 DR. $. O. LINDBERG ON ZOOPSIS. 
Turneri and dentata, which possess subcomplicate leaves, nearly 
as in Jungermania Helleri &c., C. byssacea ,islandica, and albescens 
seem to have the female inflorescence in the very apex of the 
stem, 7, e. acrogynous, although, by the growing-out of long 
branches from the lower axils of the vegetative leaves, it soon 
becomes lateral; I have at least never found on them a gastrogy- 
nous perichztium ; this fertile branch very often gives rise, from 
a lower axil, to a second of the same nature, and this to a third 
one; and the colesula is never trigonous, but always terete and 
plicate. These species, forming the latter series, may be, I think, 
taken out from Cephalozia and brought over again to Jungermania. 
In the description of C. argentea Y have used a new term for 
the calyptra (gynomitriea), which wants illustration. 
In ‘ Synopsis Hepaticarum ’* we find the Liverworts divided into . 
five tribes: Jungermaniee, Monoclee, Marchantiee, Anthoce- 
rotes, and Ricciew. Dr. Gottsche, who is best acquainted with 
these plants, has proved (see ‘ Botanische Zeitung, 1858, nn. 38 
and 39) that Monoclea is most allied to Blasia, and must thus be 
among Jungermaniee frondose, and Calobryum is a very dubious 
plant. In my ‘Musci Novi Scandinavici’ (1868), p. 296, I have 
pointed out that Ricciee bear the same relation to Marchantiee T as 
Phascee do to more highly developed Mosses. Of five tribes, thus 
but three are left, viz. Marchantiee, Jungermanniee, and Anthoce-

- t On this subject my Md Dr. Carrington, of Eccles, makes the following 
very important remark in a letter of Aug. 21, 1870 :—“ I see you arrange Sphe- 
rocarpus among the Marchantiacee. Most people have been misled by the ex- 
ternal resemblance to the Ricciee ; but the structure of the frond is altogether 
simpler, wanting the pores and lacunose stratum of the Marchantiacee ; and, 
after careful study, I believe its true place is with Jungermanniacea, of which it 
is a gymnocarpous form, holding the same relation to Aneura &c. that Riccia 
does to Marchantia. There is another solution of the question: it may be 
placed with Anthoceros as a degraded form of the Hepatice.” The former of 
these two interpretations is, I think, an ingenious and natural one, especially as 
Iam unable to discover onthe underside of the thin frond any cells with clavu- 
late incrassations on their inside, which cells are peculiar to all the Marchan- 
tiee and Ricciee (Marchantiacee); but the latter is quite opposed to the struc- 
ture and development of the fruit in the Anthocerotacee.
