30 PLANTS FROM NEW CALEDONIA, 
ter incisa ; perianthium ultra bracteas parum emersum longe obconicum, ore 
lato fimbriato segmentis cellulas uniseriatas 5-15 longis. 
Dimensions. Stems 1 inch long, diam. *2 mm. to ‘25 mm. ; with leaves 
2:5 mm. wide; leaves, lobe 1°25 mm.x:85 mm., lobule *4 mm.x-4 mm., 
lobe 1:1 mm.x:9 mm., lobule ‘4 mm.x:4 mm.; cells ‘03 mm. ; bracts, lobe 
2mm.xl mm., lobule 125 mm.x:75 mm. ; perianth 2°25 mm.x1 mm. ; 
fimbriæ at mouth ‘05 mm. to *1 mm. long. 
Obs. There are only 13 species enumerated by Stephani belonging to the 
Acutifolia section of Æadula, to which this belongs. 
It is remarkable in having the free angle of the lobule emarginate ; only 
two such species are recorded by Stephani—R. Delessertii St. from the 
Mascarene Islands, which is described by Stephani as with apex of lobule 
slightly emarginate, and XR. sinuata G. from Brazil with apex of lobule 
narrowly and deeply emarginate. 
I have pleasure in associating with this unique species the name of 
Prof. Farmer, who has named several of the species in this collection. His 
breakdown in health prevented him from completing the work, which I 
much regret, although it has given me the opportunity of studying an 
exceedingly interesting set of plants. 
Hab. Ignambi. On rocks by creek, 3000 ft. 1530. 
RADULA VIEILLARDIL Gottsche ex St. in Hedwigia, xxii. (1884) 150; 
St., Sp, Hep. iv. (1510) 226. 
Dioicous. Small pale brown in colour, epiphytic. Stems irregularly 
branched. Leaves approximate, lobe horizontal (90°), oblong, antical 
(upper) margin covering the stem, lobule patent (50°), roundish-subquadrate, 
with apex obtuse, rarely acute, tumid at the base, extending to the middle of 
the stem, upper portion complanate ; texture delicate, cells medium size 
(03 mm.—04 mm.); cuticle slightly papillose. Bracts very large; lobe 
oblong, erect. Perianth tubular, cylindrical, or narrowly clavate, slightly 
papillose, mouth entire. | 
Male plant more delicate, catkins numerous, 6 to 10 pairs of bracts, lobe 
spreading, apex obtuse, lobules closely imbricating. 
Dimensions. Stems 1 inch long, diam. ‘2 mm.; with leaves 1:75 mm. 
wide ; leaves, lobe *8 mm. x *65 mm., lobule ‘4 mm. x ‘4 mm. ; cells ‘03 mm, 
'04 mm. ; periunth 3 mm. x *8 mm. 
Obs. The strikingly large bracts and the spreading lobes of the male bracts 
readily distinguish this species from others. 
Stephani says (in Hedwigia, 1884, p. 150) that he has never seen the 
plant ; and there are several discrepancies between Gottsche’s description in 
Hedwigia and his own * Species Hepaticarum.’ 
Stephani says perianth clavate ; I find it to be equal in breadth the whole 
length or narrowly clavate: also he says leaves with large trigones; I see 
none.
