EUPHRASIA NEMOROSA AND E. CURTA 75 



to be expected that these sHghtly hairy forms of nemorosa should 

 occur in this country. 



A careful examination of the plants in my own herbarium has 

 failed to find any absolutely glabrous-leaved plants of nemorosa, 

 and it may be indeed that in England this plant is generally slightly 

 hairy, perhaps often rather more so than in the plants with which 

 Wettstein was familiar. This hairiness, however, as Wettstein 

 himself implies, does not make these plants curta var. glabrescens, 

 this last-named plant being something other than merely slightly 

 hairy nemorosa. 



If a name is necessary, the following may be suggested : 



E. NEMOROSA var. ciLiATA nov. var., a 7iemorosa typica diagno- 

 scitur foliis bracteisque, raro et calycibus ciliatis vel leviter hirsutis. 



In my opinion, however, it would be better to extend the 

 diagnosis of weworosa to read : " Folia omnia . . . glaberrima 

 rarius ciliata vel leviter hirsuta . . . Calyx glaber rarissime 

 ciliata vel leviter hirsuta . . ." 



The possibihty of a hybrid origin of both these slightly hairy 

 forms must not be overlooked. The hairy nemorosa form, at 

 least, how^ever, grows in great quantities in districts from which 

 both curta and ordinary glabrous nemorosa appear to be absent 

 entirely, and thus its hybrid nature seems so extremely unlikely 

 that it need not be further considered.

A NEW HYBEID WILLOW-HERB. 

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



Epilobium hirsutum X palustre, n. hybr. (x E. Waterfallii). 



Plantse hujus pars superior tantum a me visa est. Caulis 

 ramosissima, tenuior, teres, villosa. Folia sessilia, lineari- 

 lanceolata, admodum villoso-pubescentia, margine plus minus 

 revoluto ; media subintegra, superiora denticulata. Flores majores ; 

 sepala anguste lanceolata, apiculata, petalis speciosis saturato 

 roseis subduplo breviora. Capsulae abbreviatae, graciles, villosis- 

 simae. Semina sterilia.
