1863.] ON THE BOTANY OF MALHAM. 579 



Hellehorus foetidus, L. I have a specimen which is said to have been 

 " gathered below Malham Cove, 1839." No botanist of my acquaint- 

 ance professes to have seen the plant in situ. 



Adcea spicata, L. Gordale ! Top of Malham Cove ! " A few plants at 

 the side of the brook below Malham Cove," Dr. Windsor. 



CRUCIFER.E. 



Thlaspi alpestre, L. Malham Cove, /. Tatham. Near Malham Tarn ! 



"Very plentiful by the lead-mines betwixt Stockdale and Malham," 



Dr. TFindsor. The Malham plant is T. occitaniim, Jord. Probably 



all of Dr. Windsor's stations for T. alpestre belong to this species. 



Has he not mistaken T. occitammi for T. virens in the note to T. 



alpestre (p. 350) ? The last-mentioned variety has not been found 



in Craven. Jordan, and not Babington, is responsible for the division 



of T. alpestre. 

 HutcJiinsia petrcea, Br. "On the higher part of the furthest east cliff in 



Awes Scar, near Malham Tarn," Dr. Windsor. I have found this 



plant at the height of 450 yards. 

 CocJdearia officinalis, L. (Var. alpina,'Qah. C. groenlandica, Sm., not Linn.) 



Kirby Fell ! Hawkswick Clowder ? 

 Draha incana, L. Gordale ! Hawkswick Clowder ! Kirby Fell ! 

 D. muralis, L. Walls in the village of Malham, /. Noioell. Eocks near 



the foot of Malham Cove ! Gordale ! Under Malham Cove, Dr. 



Windsor. 

 D. verna, L. A specimen in herbarium, named D. irtjlata, Hook., but 



difficult to identify in the dried state. 

 Arabis Jdrsuta, Br. Frequent on the limestone. Several unimportant 



varieties occur. 



CISTACEiE. 



HeliantJiemum vulgare, Gsert. Gordale ! Malham Cove ! 



H. canurn. Dun. Malham Cove ! This plant, subdivided by Linnaeus 

 into Cistiis marifolitis, anglicus, etc., is by others regarded as merely 

 a dwarf form of H. vidgare. This would be difficult to prove. I 

 have seen the two plants growing side by side under precisely similar 

 conditions, nor has any intermediate form been observed. The fol- 

 lowing diagnosis was made upon fresh specimens. (August, 1859.) 



Helianthemum canum, Dun. H. vulgaee, Gcert. 

 Hoot — Long, woody. 



Stem — Decumbent, shrubby, covered Stem — Procumbent, shrubby. 



with numerous miniite scars. 



Leaves — Without stipules, ovate, op- Leaves — ^Witli stipules, ovate, opposite, 



posite, flat, hoary beneath, hairy flattish, hoaiy beneath, thinly covered 



above. with adpressed hairs above, margin 



slightly reflexed.
