MR. G. MURRAY ON BOODLEA. 243 
Hab. Perak, at Ulu Batang Padang; Wray, n. 1605 ; Scorte- 
chini, n. 868. Hb. Kew. 
A most distinct species. The leaves are much broader than in 
any other, also fewer and more distant, while the bracts at the 
base of the inflorescence are not so distinctly developed. Wray 
notes the plant as “3 ft. high,” but his specimen (with roots 
attached) is but little over half this height. His specimen is in 
fruit only, but Scortechini’s has both flowers and fruit. 
On Boodlea, a new Genus of Siphonocladacez.

A FEW weeks ago Dr. G. B. De Toni, on receiving a paper on 
Struvea recently published by Mr. Boodle and myself (‘ Annals of 
Botany,’ vol. ii.), suggested to me in a letter that a species of 
Cladophora collected by the * Challenger’ Expedition on the coast 
of Japan, and described in our Journal (vol. xv. p. 451) by Professor 
Dickie as a new species, viz. C. coacta, Dickie, would be worth 
examination, since, so far as he could judge from the reference to 
* anastomosing filaments " in the description, it appeared to be a 
Struvea. Thetypeis in the British Museum— both Prof. Dickie's 
own specimens and the distributed ‘Challenger’ series. It was 
therefore hardly likely that it could have escaped us in our recent 
work at the genus; but the allusion to its “ anastomosing ” fila- 
ments certainly excited curiosity. The specimens had not been 
long under examination when it appeared that the so-called 
** anastomosing ” was in a double sense like that of Struvea—first, 
it was not true anastomosis, but adhesion without open commu- 
nication ; and, secondly, this adhesion was effected by tenacula 
remarkably like those of Struvea (compare * Annals of Botany, 
vol. ii. pl. xvi. figs. 1f, 3d, 3e, 3f, with figs. 2 and 3 of the 
Plate accompanying this paper). At the same time it became 
apparent that this alga possessed no regular frond or stalk like a 
Struvea, but resembled Microdietyon more strongly in this respect. 
The tenacula, however, are very different from those of Micro- 
dictyon, and, more important still, the branching also. In Miero- 
dictyon the filaments spread out in one plane and form a definite 
net; in this organism they run in all directions (Pl. XLIX. fig. 1),
