§ 305: NOTES ON HEPATICOLOGY by C. F. Austin. 
Frullania Donnellii, ~. sg.—Autoica, rufescens, fere minima 
generis, caule cum filis longissimis nigris cornicularioidis (forsitan 
ad Fungos pertinentibus) intertexto confertim simpliciter pinnatim 
vel subfasciculatim ramoso, ramulis brevissimis subsemierectis obtu- 
sissimis, foliis ovato-rotundis covexiusculis obtusis integerrimis con- 
tiguis vel imbricatis, auricula majuscula oblongo-clavata vel subcy- 
lindrica a caule distante et cum eo subparalleli vel deflexa (haud 
divergente), lobulo interjecto subulato minutissimo, amphigastriis 
caule duplo latioribus subobovatis bifidis, lobis obtusiusculis, peri- 
anthio obcuneato-oblongo, dorso planiusculo, ventre versus apicem 
compressum truncatum apiculatum brcvissime unicarinato, foliis 
amphigastriisque involucralibus magnis profunde inciso-serratis : 
androecium minutum globosum brevipedunculatum. 
East Florida, Mar. 1877. Capt. 7. Donnedl Smith. 
A very small species, readily distinguished by the characters 
above denoted. Auricle longer and more distant from the stem, 
amphigastria wider, involucre larger and incised-serrate, perianth 
less expanded at the apex and somewhat different in texture, male 
spike globose and somewhat hidden under the leaves, otherwise 
much like #. Knuzei, var. (F. Drummondi, Tayl.).—F. fragilifolia, 
TayL., (F. polysticta, Mont, F. Sullivantia, Aust.) is also of 
about the same size, but the ramificationis more vague, leaves nar- 
rower and marked by a medial line or patch of bead-like cells, 
auricle shorter and close to the stem, involucral leaves much 
less deeply serrate, perianth composed of much smailer cells, 
&c.—F. gymnotis, Nees. (F. macularis, Tayu., &. Leaana, AusT., a 
tropical species, erroneously attributed to this country by me, through 
a specimen in Herb Tayt., from Para, Brazil, but labelled ‘“Cincin- 
nati, Ohio,’’) has the leaves apiculate and composed of more oval 
cells, those at the base conspicuously enlarged, auricle twice as dis- 
tant from the stem, branch leaves smaller and more closely imbri- 
cated, &c. 
Frullania (/udu/a) piligera.—F. Hutchinsie var. f, Synop. 
Hepat. p. 426.-—-F. Hutchinste proxima ; differt tamen foliis minus 
rotundis apice magis minusve piligeris (pilis 1-3-6 longis) reti magis 
ovali, auricula magis clavata, amphigastriis angustioribus, etc. 
Sandwich Islands, Baldwin (Eaton). Java: (Synop. Hepat.) 
Radula Caloosiensis, 7. s¢.—Dioica, flavicans; caule brevi 
rigidulo arcte repente parce ramoso vix subpinnato, foliis convexis 
(tumidulis) integerrimis vel obscure crenulatis obtusis, margine 
plerumque gemmiparo, lobulo inferiore majusculo subacuminulato 
vel obtuso sepe subundulato margine interiore cauli adnato et 
supra eum subprotracto, reti fere ut in &. complanata mediocri, 
cellulis subzequalibus hexagono-rotundis supra convexis farctis valde 
opacis intercalaribus angustioribus hyalinis, perianthio breviusculo 
e basi obconica late oblongo-quadrato valde compresso, dorso len- 
issime convexo, ore bilabiato, labiis fere integris subdecurvis; spicula 
masc. longiuscula laxiuscula subinterrupta. 
Caloosa, Florida, March, 1878.
