Descr.: The beautiful plant somewhat resembles in its external 

 appearence to Bonnemaisonia Asparagoides. The frond is coespi- 

 tose, attached to substratum by fibrous roots, filiform and com- 

 pressed, 2 — 3 times pinnate, alternate and distichous, about 15 cm. 

 high and 0.5 mm. broad in the lower portion. - The entire plant 

 is primarily divided into some main divisions which ramify in 

 successive order, and the general outline of one main segment is 

 broadly oval or lanceolate. The rachis of main branches are 

 very slightly flexuous. The persistent, coloured, monosiphonous 

 " Uaar bl cittern ' aris.e regularly alternating along both sides of 

 .branches,, in such a manner that those issuing from every two 

 consecutive nodes stand in . alternation on the sides. They are 

 normally branched in a pectinate manner, that is 6-7 laciniae 

 issue from every articulation along the upper side of the mono- 

 siphonous rachis. The latter, when young, is incurved towards the 

 apex of the shoot which bears those " Haarolattern, but soon 

 becomes straight and patent, and then either gradually becomes 

 almost horizontal or curves backwards. Laciniae are directed 

 outwards, standing almost parallel to one another. The rachis 

 and laciniae are all sharply pointed at the ends. " Langtrieb". 

 defiinte or indefinite, developes from the upper one of the two 

 consecutive " Haarblattcrn." Consequently, " Lanp"triebe arise, 

 as a rule, alternately from every 6th joint ； but when they are 

 more widely separated, they sometimes arise from 10th, or when 

 more approached, from 2nd, articulation. Simple, or not pectin- 

 ated " riaarblattern " are of rather rare occurrence except on 

 the fertile branches ； and, when they are present in the sterile 

 portion, they are mostly placed beneath the pectinated one. 

 Again, their disposition is commonly distichous, but not without 

 some irrepfulanties, especially in sporiferous branches where they 

 are arranp-ed on all sides. .
