Freziera , which lie regarded as synonymous with Froteum, though 
his diagnosis excludes F. theceoides Sw. It’ De Candolle had been 
consistent, he should have used the name Froteum for this genus. 
It is a nice point whether we can regard Freziera as dating from 
De Candolle, or whether we must wait till Choisy’s Memoir for a 
diagnosis of it as a genus distinct from Froteum. Sprague suggests 
that Lettsomia Ruiz and Pa von (1794) is an earlier name for 
Freziera Choisy. Choisy regarded Lettsomia as a distinct genus, 
though botanists generally take Bentham’s view that the two are 
congeneric. But Lettsomia Roxb., a later name for a group of 
species of Convolvulacece , has been used in that sense by Clarke in 
the Flora of British India, and it is conceivable that botanists may 
prefer to retain it as a nomen conservandum, in which case Lettsomia 
Ruiz and Pavon is ruled out. In any case, it is antedated by 
Froteum Swartz. 
3. Laplacea or Lindleya. 
We referred to these names as illustrating a rather nice point. 
Both Blake and Sprague assume that Lindleya should be accepted as 
the earliest published name, but the circumstances of the publication 
are so unusual that we thought them worth recording more fully than 
had been done by either of the two previous writers. We can imagine 
a lover of nomenclature discussion taking up the position that Lind¬ 
leya Nees was not legally published in Flora, 1821. We agree 
with Mr. Sprague’s concluding remarks: we did not propose to use 
the name Lindleya nor to make new combinations. 
THE DISTRIBUTION OP EUPHRASIA IN CORNWALL. 
By F. Rilston.

Eleven species of Fuphrasia have been recorded for Cornwall, 
viz. F. stricta Host., F. borealis Towns., F. occidentals Wettst., 
F. curta, Fries, F. brevipila Burnat and Gremli, F. Vigursii Davey, 
F. nemorosa H. Mart., F. gracilis Fries, F. confusa Pugsley, 
F. Kerneri Wettst., and F. Rostkoviana Hayne. 
Of these, F. gracilis and F. Vigursii are distinctly heathland 
species. The former, a very distinct and easily-recognized plant, 
occurs with considerable frequency, but is always, I believe, confined 
to peaty or heathy ground. F. Vigursii is a plant of similar, 
though somewhat wider, range of habitat, but more restricted terri¬ 
torial range, occurring chiefly on more or less level heathy places 
north of the watershed. In respect of habitat it differs from F. Rost¬ 
koviana , which is usually a plant of rough hillsides, occurring thus 
on the granite slopes of Kit Hill, Cheese wring, Caradon, and Helman 
Tor in East Cornwall, as well as in steep uncultivated slopes nearer 
the coast. I have also seen specimens collected by Rev. H. H. 
Harvey from Carnmenellis, another granite hill, near Redruth. 
F. Rostkoviana grows also on roadside and other banks, but, though 
occasionally found on level spots, seems never to luxuriate there.
