170 HARROW PLANTS. [June, 



HARROW PLANTS. 



Remarks on the List of Harroiv Plants reprinted in ' Phytologist,' 



p. 110. 



Corydalis lutea, from what is said at p. 118, requires the "^. 



Coronopus didyma. The omission of C. Ruellii renders it pro- 

 bable that the former name has been misapplied. 



Barbarea arcuata. There is a variety of 5. vulgaris with patent 

 pods liable to be mistaken for the true B. arcuata, which has 

 much larger flowers than B. vulgaris. Which of the two occurs 

 at Harrow ? 



Brassica Rapa and B. Napus surely require the ^, if not the 

 brackets of exclusion. 



Sinapis nigra. Is this ever grown as a crop at Harrow ? 

 Usually found along damp hedges rather than as a colonist. Is 

 S. alba absent ? 



Viola tricolor. " In gardens," yet the ^ is omitted. Is this 

 the degenerated garden pansy ? 



Sagina. Is S. apetala not found upon the same '' old walls" 

 that produce S. procumbens ? 



Acer Pseudoplatanus probably requires the *. 



Prunus insititia seems also very dubiously wild. The Bullace 

 is apparently often supplied by nurserymen for planting in field 

 hedges along with the blackthorn. 



Rosa villosa. Can this be R. tomentosa, of which there are so 

 many varieties? 



Cratagus. Is it intended to press its claims to rank as a dis- 

 tinct species? Few English botanists are likely to accept it as 

 more than a var. 



Ribes rubrum and R. Grossularia. It would be interesting to 

 know something of their title to be considered wild. 



Sedum reflexum. The '^ is surely required for such a locality 

 as " old walls." It is to be remembered this Sedum is, in its 

 native habitat, a subalpine species. 



Viburnum Opulus. Why should this of the two pass as native, 

 when its stations are usually in damp woods ? If the objections 

 to admitting V. Lantana as indigenous depend upon its being a 

 " chalk plant," there are several others in the list to show the 

 presence of calcareous ingredients in the soil, e.g. Hypericum
