and general appearance of the two plants being quite simi- 
lar ; but besides the minor differences mentioned below, the 
present is abundantly distinct as a species, having a straight 
and regular (not oblique irregular) flower, and a four-winged 
(not wingless) ovary; thus affording a good example of 
closely allied species, representing each other in different 
regions or elevations. The E. truncatum 1 have never 
observed growing at a greater height on the mountain than 
about four thousand five hundred feet ; while above that 
line, and to an elevation of nearly six thousand feet, nothing 
but E. Russedlianum is to be found. 
The brilliant flowers are produced in the month of May, 
and had not my visits to the Organ Mountains been fortu- 
nately made at that season, I certainly should have passed 
by this species as E. truncatum. G. Gardner. 
(We can readily participate in the pleasure Mr. Garpner 
must have experienced in discovering this beautiful Epi- 
phyllous plant and dedicating it to his distinguished patron, 
the Duke of Bedford, a nobleman, who, in the short time 
of Mr. Garpner’s absence (scarcely three years) has amass- 
ed such a collection of Cactoid Plants at Woburn Abbey, 
as must be seen to be appreciated, and with which none in 
the kingdom, that I know of, can be compared, except it 
be that of Harris, Esq., of Kingsbury, near Hendon. 
In the stoves at Woburn, the great columnar kinds of 
Crrevs, thirty feet high, (and, especially the noble speci- 
mens of C. senilis two of which have attained to twelve 
feet, and are clothed with long, pendent white hairs) con- 
_ trast admirably with the strangely broad and depressed 
forms of the Metocacrus and Ecuinocactus group, beset, 
too, as these are, with spines of every shape and size and 
colour :—again, the latter kinds present a most curious 
difference of aspect from the flattened and jointed stems of 
the Opuntiz and Epipnyrta; while the magnitude and fra- 
grance of the blossoms of some, and the brilliancy of colour 
in others, are surpassed by few vegetable productions. 
The arrangement and high health and vigour of the plants 
at Woburn reflect the utmost credit on the able gardener, 
Mr. Forses.*
