EAST RIDING BOTANICAL NOTES, 1905. 



DURING 1905, a quiet but steady season's work has 

 been accomplished. Little tracts of slightly fresh 

 ground have been visited near Houghton Woods, 

 Figham Common, Beverley Long Lane, Beverley Parks, &c. 

 Several new stations for East Riding plants have been made 

 out, e.g., the Greater Burnet, Poterium officinale, in an old 

 sandvlane near Hotham ; Viola tricolor in the same place ; 

 Nepeia Cataria in Beverley Long Lane (pointed out by its 

 first finder there, Miss Jackson, of Thearne Hall) ; Astragalus 

 danicus on Garton Wold, near the Sykes Monument ; Allium 

 vineale near Saltend Common ; . isplenium Ruta-muraria on an 

 old bridge near Figham Common. New localities have also 

 been found for Polystichum aculeatum near Birkhill ; the Petty 

 Whin (Genista anglica) among the heather between Snake 

 Hall and Duck Nest and Bucla rubra in sandy fields at Snake 

 Hall. The Marsh Pea [Lathyrus palustris) vegetated luxuri- 

 antlv in its only Yorkshire habitat this spring, flowered 

 plentifully in early July, and was in fruit in August. The 

 Bee Orchis, at Kelsey Hill, was seen in June last. 



One plant, quite a new record for the East Riding, viz., 

 Leonurus cardiaca, was discovered at Barlby, near Skipwith 

 Common, in August last by Mr. Wm. Bromby. 



The West Dock Extension is no longer available as a 

 productive alien botanical garden. The North Eastern 

 Railway Company have killed that, but the scientific pure 

 and simple must give way to the economic, and we must not 

 crumble, for there still remains an immense amount of work 

 "to be done in many departments of botany.
