162 RARE OR CRITICAL W. SURREY PLANTS, 1894. 



No. 222, which is preserved in the British Museum ; this drawing 

 shows the identity of the plant with B. myosuroides Kiltz., as 

 figured in the Tah. Phyc. vi. t. 77, fig. 1. 



Among the algse sent to me some while ago from British 

 Kaffraria by Mr. Flanagan is a new species of Bryopsis, which may 

 be placed in the same division of the genus as B. plumosn, B. pen- 

 nata, and B. setacea, i. e., that devoted to species with a distichous 

 initial plume. It difi"ers from B. setacea in having the whole of the 

 upper half of the stem clothed with ramenta, and tapering at the 

 apex to a point. From B. pennata it may be distinguished by its 

 more robust habit, the gradually tapering apex, and by the long, 

 bare stem below the middle. I have dedicated this species to its 

 finder, Mr. Flanagan, a most assiduous and successful collector, to 

 whom I owe the possession of many interesting and rare forms of 

 Cape algae. The diagnosis is as follows : — 



B. Flanagani, n. sp. Fronde lanceolata, muris ratti caudas 

 simili, erecta, quum adulta sit 11 cm. alta, dimidiam inferiorem 

 partem nuda, superiorem ramulis simplicibus distichis ornata, qui 

 haud amplius quam duo cm. a summo minui incipiunt ; quum 

 adolescat summam quintam partem caulis ramulis vestitam habet, 

 qui ab imo usque ad apicem Bryopsis plumosae more minuuntur.

Among the algfe collected by Ferguson in Ceylon, No. 37, is a 

 form of Bryopsis which appears to unite B. setacea and B. pennata. 

 In some plants the tip only is clothed with ramenta, resembling in 

 shape and size B. setacea ; while other stems have the ramenta 

 continued either with or without intervals nearly to the base. Such 

 plants as these make one realise the truth of what the elder Agardh 

 said of this genus years ago : — " Quid varietas, quid species sit, in 

 hoc genere definitu difficillimum neque adhuc definitum." — Ag. 

 Sp. i. 448.

RAEE OR CRITICAL W. SURREY PLANTS, 1894. 



By the Rev. E. S. Marshall, M.A., F.L.S. 



Dr. Focke and the Rev. W. Moyle Rogers spent a few days with 

 me last August, when a few species of Rubus were added to the 

 county list, and several hybrids were met with which were not 

 previously known to exist. As these have not been mentioned by 

 Mr. Rogers in his recent paper, it may be worth while to record 

 them. The forms of Erophila in my neighbourhood received some 

 special attention, and two of them at least appear to me to deserve 

 segregate rank; but as yet I have failed to identify them satis- 

 factorily with French types. A couple of excursions were made 

 with Capt. Wolley Dod to the Sussex border, near Baynards and 

 Alfold, and to the Hants border, about Blackwater and Frimley.
