stalk in the month of March and is mature in April.” This, 
it hardly needs to be remarked, much excels any description 
of Hepaticse that we have seen up to thistime. The allusions 
to the areolz and pores of the thallus and to the spore-dust 
are especially noteworthy. The paragraph has the heading 
“Lichen Plinii primus,” to which title Colamna adds the 
word “ pileatus.” 
The Pellia, supposed by Lindberg to be endiviefolia, is 
described under the heading “ Lichen alter minor caule cal- 
ceato brodedeuevw.” It is said that “ this delights in the same 
places and arises in a similar manner, but is smaller in every 
part, on account of which difference we have called it ‘the 
less.’ The stem is irodcdenevo, that is tosay, calceate. It has 
a more delicate and smaller leaf, very thin, translucent, so 
that it is indistinctly seen in the shade; when it is older, it 
passes from purple to blackish. It is smooth and not’ 
squamous, but from the back something almost like a scab- 
bard or calceus, with a fimbriate mouth, arises a little, from 
which at the Ides of March there springs forth a smooth, 
blackish-green little ball of the size of the chick-pea [ Orobus]. 
This afterwards leaps upward, supported by a stem four 
fingers high; it is now a little lutescent and dehisces into a 
yellow flower of four leaflets, containing within a great quan- 
tity of very fine impalpable threads. The stem which was 
round, smooth, naked, juicy, diaphanous, white, and easily 
injured by the touch, falls to the ground on drying. The 
roots are silky-villous—none more delicate can be found. 
This plant is smaller by a fourth part than the one described 
above.” 
Targionia hypophylla is saluted as the “Lichen alter 
acaulis tropvAAoxapros” and is described in words which we 
translate as follows: ‘This delights in a habitat like those 
of the former species and is met with at the same time in 
mossy places and others such as have been mentioned above. 
This kind is the smallest, for its leaves rarely equal in mag- 
nitude the nail of the little finger. It is green and is
