SHORT NOTES. 



Bedfordshire Plants. — Fuutinalis dolosa is plentiful in ponds 

 at Limhury, occasionally fruiting. First record, 1882. I owe it to 

 Mr. H. N. Dixon that this form has been distinguished by Mr. 

 Cardot from F. antipijretlca. — Orthotriehuut. pu'chtiluui ft. Winteii. 

 On elder trees near water, Luton Hoo Park ; July, 1892. First 

 discovered by my son Edgar. — Riccia Jiuitans. Plentiful in a pond 

 by the island in Luton Hoo Park; Sept. 1896. Specimens of the 

 above three species are sent for the British Museum Herbarium. —

Hybrid Forms of Pyrus. — At the meeting of the Edinburgh 

 Botanical Society on Jan. 11th, a communication by Prof. Koehne 

 on some forms of the Aria section of Pyrus was read. The ob- 

 servations were made on a number of specimens collected by Dr. 

 Landsborough of Kilmarnock, in Arran, last year (which were 

 transmitted by Prof. Balfour to Prof. Conwentz, of Dantzic, an 

 authority on the genus), and also on specimens collected by Kev. 

 Augustin Ley in Breconshire. According to Prof. Koehne, the 

 wbole of the forms received by him from Breconshire and Arran 

 belong to two species, viz. (1) Aria siiecica Koehne [Cratceyus Aria 

 var. suecica L. ; Pyrus intermedia Ehrh. ; Surbus scandica Fries ; 

 /'. decipiens Bechst. ; Aria scandica Decne. ; P. scandica Babingt.) ; 

 {ind (2) Surbm Auciiparia (Pyras Aucuparia Gnevtn.). Of the two 

 specimens mentioned by Prof. Koehne as having been received from 

 Breconshire, one (collected from a limestone cliff near Merthyr 

 Tydvil by Mr. Ley on May 28tb, 1896) he believes to be the typical 

 Aria suecica Koehne; while the other he considers to be a hybrid 

 between that species and Sorbus Aucuparia, but very closely related 

 to the former. All the Arran plants he declares to be hybrids. 

 Two from Glen Catacol he considers to be the typical hybrid Aria 

 suecica x Surbus Aucuparia [Cratceyus Aria vav. fennica Ij. ; Sorbus 

 hybrida L. & W. Koch ; S. fennica G. Koch) ; while all the others hp 

 considers to be intermediate forms between this and A. suecica. It 

 would therefore appear that A. suecica Koehne had not been collected 

 in Arran by Dr. Landsborough ; and as Prof. Conwentz, when he 

 visited the Royal Botanic Garden, Edinburgh, last year, did not find 

 that species in the herbarium, there seems to bo some doubt as to 

 its occurrence in Arran, especially as the collection contains a con- 

 siderable number of specimens of what are supposed to be that 

 species from various parts of the island. Prof. Koehne further 

 remarks that, he is persuaded that if a careful search be made,
