18 PLANTS FROM NEW CALEDONIA. 
maxima cylindrica levis paulo clavata, medio cellulas 6 crassa, ore parvo, 
umbilicata. 
Andreecia ramis binis brevibus sita, alveolis in 3 paria dispositis. Capsulee 
valve bistratæ, sectione transversä cellulas quadratas, cellularum interiorum 
pariete exteriore crenulato, exhibentes. Spore verruculosæ fusco-brunneæ. 
Elateres angusti attenuati pallide lutei monospiri, spirå 10-plo cireumvoluta. 
Dimensions. Fronds 1 to 14 inch long, 5 mm. wide, *6 mm, thick. at the 
middle; calyptra 10 mm. long x1°5 mm. thick ; wall of capsule ‘03 mm. 
thick ; spores ‘02 mm. ; elaters ‘223 mm. long x ‘01 wide. 
Obs. The very large calyptra for this medium-sized plant is exceptional. 
In the whole of Stephani’s ‘Species Hepaticarum ’ he describes only a few 
with very large calyptra (5 mm. long); A. longiflora St. from Tasmania, 
8 mm. long; A. pulvinata from Bolivia (Herzog), veered as with 
* ealyptra gigantea, 3 mm. long ” [ Printer's mistake probably !] ; A. maxima 
(Schiffner) from Java and Sumatra, a plant 10 cent. long aud n mm. wide 
having a calyptra 15 mm. long x 2 mm. thick; my A. macrantha cannot be 
a small form of this, for it is monoicous with calyptra smooth. 
Hab. Tgnambi. On rocks by creek, 3000 ft. 1530. 
ANEURA LOBATA (Schiffn.), St. in Bull. Herb. Boiss. vii. (1899) 761. 
Riccardia lobata Schiffn. in Denkschr. Kais. Ak. Wien, Ixvii. (1899) 178. 
Hab. Mont Koghi. From bark and rocks, near stream, 1000 ft. Forest. 
METZGERIA LUCENS St., Sp. Hep. Suppl. vi. (1917) 54. 
Sterile; small; flaccid; ramose, branches postical; costa delicate, 
3 to 4 cells thick, 2 antical and 2 postical cells, narrowly elliptic ; 
antical plane, postical projecting ; costa, wings, and margin without setze ; 
cells very large. 
Dimensions. Stems 1 inch long, 1:5 mm. wide ; costa *2 mm. wide ; cells 
*15 mm. x 125 mm. 
Obs. Stephani records in Sp. Hep. Suppl. three species without setze, two 
of which have very large cells, and one of them, M. marginata St., has very 
narrow (‘036 mm. x:09 mm.) marginal cells; he does not mention this 
character in his description of M. lucens, although he gives the size of the 
marginal cells of this species as 027 mm. x:09 mm. Prof. Compton's plant 
agrees best with the brief description of M. lucens. 
Endemic. 
Hab. Ignambi. On gneiss rocks, in moist air, 3000 ft. 1531. 
METZGERIA MARGINATA St., Sp. Hep. Suppl. vi. (1917) 55. 
Dioicous ; fronds 1 mm. wide ; setæ on costa and margins only ; cells 
+1 mm. x:075 mm., marginal cells very small ; only young 9 seen. 
Hab. Mont Arago. Bark of tree, in moist forest, 2000 ft. 1450.
