500 DECADKS PLANTAEUM NOVARUM AUSTRO-AFRICANARUM. 



it grew C. aspera Willd. var. subinennis Kuetz., C. canescens Loisel. 

 (only known before in Ireland from Mr. Scully's Co. Kerry station), 

 and Tohjpclla gloinerata Leouh. — " a form approaching T. nidifica " 

 (Groves in litt.). I l)elieve that this sheet of water requires a more 

 systematic search ; the day of my visit was dull and gusty, and the 

 only available drag was an umbrella, as I had not expected to come 

 across aquatic plants. Chara vulgaris L. var. papillata Wallr. is 

 plentiful in marsh-ditches a little way north of the lake.

 from the latter by the want of the slender horns on the capsule ;
