Tyssen gre Falkland Sands; January, 1868, Cunningham 
106 in Her 
interstate These specimens have been named by Stephani 
Lophocolea humilis, Hook. f. & Tayl. It is a true Lophocolea 
but widely different from L. hrceniite 
The nearest species from the Antarctic according to the 
description is Lophocolea microstipula, St., also collected by 
Cunningham (Fretum magellanicum), which has obovate entire 
leaves with a narrow base. Nothing is said of any retuse, leaves 
and the underleaves are described as free. 
Conoscyphus flaccidus, Pearson, sp.nov. Dioicous. Small ; 
pale brown in colour, apices dark brown; loosely caespitose. 
Stem on cross-section slightly angular and frontally compressed ; 
simple or slightly ramose, soft, flaccid, delicate texture; branches 
postical, erect, almost equal in size to stem, rhizoids delicate, 
hyaline, arising from the base of the underleaves in bunches. 
Leaves secund, imbricate or amplexicaul, erecto-patent (30°), 
reniform or orbicular, margin entire except that at the antical 
(lower) base there are usually 1 to 4 teeth, antical margin decurrent, 
crispate; postical (upper) margin rotundate, slightly ampliate, 
extending to beyond the stem, rarely furnished with 2 very 
minute teeth; texture soft, flaccid; cuticule papillose; cells 
small, irregular in size, roundish, walls thick, trigones large. 
Underleaves free from the leaves, large, concave, broadly oval, 
bifid to 1/3rd, unidentate on both sides, segments acute, sinus 
wide, rounded. No antheridia or archegonia were seen. 
Dimensions. Stems 2 em. long; with leaves 1 mm. wide; 
diameter 0-1 mm. to 0-2 mm.; leaves 0-9 mm. high x 1-25 mm. 
broad; cells 0-02 mm.; underleaves 0-5 mm. X 0-4 mm., 
segments 0-15 mm., 0-45 mm. X 0-4 mm., segments 0-15 mm.

Observations. The soft, flaccid texture of the plant with the 
reniform or orbiculate leaves and their dentate, crispate base 
distinguish this species from any other; some cells are free from 
enna mS and are larger, giving the leaves an ocellate 
appearan 
Its suns ally is Conoscyphus trapezioides, Sande-Lacoste, 
from Java, from which it differs in the shape of its leaves and 
underleaves. Conoscyphus trapezioides (Sande-Lacoste) St. 
(= Chiloscyphus trapezioides, Sande-Lacoste,) has been made a 
synonym of Conoscyphus inflexifolium, Mitten, by Stephani, to 
which species he also refers Diploscyphus borneensis, De Notaris ; 
if the descriptions and figures of Sande-Lacoste and De Notaris are 
of any value this reference is difficult to understand. 
Specimens of Conoscyphus borneensis collected by Prof. 
Setchell in Tutuila agree exactly with De Notaris’s neces 
and figures. The specimens named by Stephani Lophoco
