368 MR. JAMES GROVES: 
collected by Professor Agharkar io 1912, in Kathiawar, agrees with 
N. batrachosperma in having the branchlets usually only twice forked, with 
gametangia produced at the first forking, but has 6 branchlets in a whorl, 
and lacks the characteristic broad flanges of the oospore ridges. 
The distribution of the species as at present known is very disconnected, 
but it is probably often overlooked on account of its diminutive size. It has 
been found ina number of European countries, in Japan, North America, 
and Australia. 
11. NITELLA OLIGOSPIRA Braun. 
6. Bengal. Griffith (Herb. Calcutta). 
Sucksagur, near Calcutta, no. 308. Sir G. Watt. 
Recorded by Braun from (2) Lahore and (10) Pegu, also so named by 
him from Nowkreem, Khasia, 5000', Herb. Hooker, and from Nicobar I. 
by Nordstedt. 
N. oligospira is characteristically a tropical species, occurring in Ceylon, 
Java, Japan ; Comoro Islands; Texas ; West Indies ; Venezuela and Brazil. 
12. N. MICROGLOCHINX Braun. 
A specimen collected by G. M. Woodrow at Ratnagiri, 1893, no. 2, has 
the remarkably short dactyls of this species, but I have not seen ripe fruit. 
N. microglochin was described by Braun from a plant collected by S. Kurz 
in the Kolodyne Valley, Aracan, and I do not know of any other record of it. 
Tt may possibly be merely an extreme form of one of the other species of 
the Brachydactyla.

Perak, 1896, no. 7144. H. N. Ridley. 
Penang, no. 1887. 77. N. Ridley. 
Occurs also in Ceylon and Java; South Africa and Madagascar ; North 
and South America, and West Indies.

11%, Singapore, 1896. T. B. Blow, 
Recorded by Braun from (5) Coromandel Coast, (10) Pegu, and the 
Nicobar Islands. Roxburgh recorded it from (6) “tanks and stagnant sweet 
water near Calcutta.” Although there seems to have been some confusion 
as to the earlier plants circulated under this name, I think there can be none 
as regards the identification of Roxburgh’s plant, and therefore that of 
Agardh and Bruzelius based thereon. Both the latter authors say “ nueulis
