114 THE ORCHID REVIEW. 
purple tips, and the lip sulphur- yellow and white tipped with bright rose. 
As in the case of the seed parent, the deep maroon blotch is absent; but 
close to the base, on either side of the pinkish white fleshy disc, are a 
number of radiating deep maroon lines, just where some lighter streaks 
occur in D, primulinum. With the exception of colour these characters are 
well shown in our figure. This flower was taken from a plant from the 
same batch of seedlings, kindly sent by Messrs. Sander, but it is not equal 
to the original form, now in the collection of W. R. Lee, Esq., of Auden- 
shaw, Manchester, having ‘both smaller flowers and narrower petals. 
Whether the difference is permanent we cannot say. It is surprising how 
small is the resemblance which this hybrid bears to the seed parent, the 
only obvious character being the absence of the maroon disc. We may 
point out that the dark throat of the lip seen in our figure arises from shade, 
this being one of the drawbacks of the photographic process, though it is 
more than compensated for by superior accuracy in other respects. D. x 
Rolfez is as free growing and floriferous as D. nobile, and is a very charming 
plant. 
D. x RoLFE# VAR. ROSEUM.—Fig. Io represents a very interesting 
plant from the collection of Major-General E. S. Berkeley, of Bitterne 
Park, Southampton, who informs us that it appeared among some imported 
D. nobile sold by Messrs. Protheroe and Morris about three years ago. It 
was a tiny little piece, but produced a flower on the imported stem, and 
though weak it was at once seen to be very distinct, and probably a natural 
hybrid. It has now developed into a respectable plant. Like the preceding, 
it has no maroon blotch on the lip, while the radiating lines near the base 
are also very similar, and the habit quite that of D. nobile. It shows such 
a substantial agreement in character with D. x Rolfez as to leave little 
doubt of its being a natural hybrid derived from the same two species, which 
are known to grow together in Sikkim. The present form is considerably 
brighter in colour than the original, and, as the figure shows, is also more 
like D. nobile in the shape of the lip. The segments would appear to be 
less spreading, but this is partly due to the fact that the flower was scarcely 
as fresh when photographed. It is a very beautiful variety, and owing to its 
brighter colour may bear the name of variety roseum. Before the preceding 
was known it might perhaps have passed as a variety of D. nobile. 
DENDROBIUM NOBILE is represented in Fig. 11—a good well-shaped 
flower, though not quite identical with the original Chinese form. The fact 
is this species is excessively variable, and we have received from Messrs. 
Sander at least a score of forms from recent importations, no two of which 
are alike. One of them is here represented. The remaining four varieties 
figured are from the collection of W. Thompson, Esq., Walton Grange, 
Stone, Staffordshire, kindly sent by Mr. W. Stevens, gardener, with a few 
of the more typical forms.
