54 BALFOUR—NEW SPECIES OF PRIMULA. 
below.* The diagnostic characters are these :—P. Engleri, 
Knuth has thin papyraceous leaves which are rarely petiolate. 
Farrer and Purdom say of P. Viola-grandis, Farrer et Purdom that 
the leaves are very thick and flannelly and have fleshy stalwart 
stalks. The interpretation of Knuth’s statement that in his 
plant the scape is destitute of basal scales is not quite clear. 
No Omphalogramma has scales on the scape, and I must assume 
that Knuth refers to the bud scales around the foliage leaf tuft. 
Such scales are distinctly present in P. Viola-grandis, Farrer 
et Purdom. en Knuth says nothing about any capitate 
ae interspersed amongst the long white hairs on the leaves 
his plant. In P. Viola-grandis Farrer et Purdom these 
are abundant and so evident that no careful describer could 
miss seeing them. In the dried specimens they are bright red ; 
whether that is the colour in the living leaf I do not know. 
The scape of P. Viola-grandis, Farrer et Purdom is much 
longer than the leaves. In Knuth’s plant the scape is described 
as se slightly longer than the leaves. Knuth says of P. 
, Knuth that the calyx is widely campanulate. That 
panded fits P. Viola-grandis, Farrer et Purdom where the calyx 
tube is a shallow cup. Lastly, in the corolla—the throat in 
P. Englert, Knuth is said to be densely puberulous with short 
hairs—its colour is not mentioned; in P. Viola-grandis, Farrer 
et Purdom the throat is hairless and is whitish. The corolla 
lobes of P. Englert, Knuth are broadly obovate and retuse 
slightly incised. In P. Viola-grandis, Farrer et Purdom they 
are narrowly obovate or spathulate and are emarginate with 
entire segments. The sum of characters suffices to justify the 
naming of Mr. Farrer’s plant as a new species, and its area, it 
will be noted, is some distance from that of P. Engleri, Knuth.
