THE ORCHID REVIEW. 269 
but this is effectually precluded by the terms of Reichenbach’s will, by which 
his whole collection remains sealed at Vienna for twenty-five years from the 
date of his death. It is a question whether the botanical world generally 
would not have promoted the true interests of the science, and discouraged 
similar unworthy vagaries for the future, by agreeing at the recent Genoa 
Congress that the usual rule of priority in nomenclature should not hold good 
in any case where the only type specimen existed in Reichenbach’s 
herbarium, and where no other specimen named by him was available for 
reference elsewhere. At present it can only be said that this is probably 
Reichenbach’s plant.” Pterygodium Newdigate, Bolus (t. 99), is remarkable 
for having a cleistogamous form, which is also represented. This is noted 
as abundant, while the normal form is rare. This cleistogamous form is 
very curious. ‘‘ No opened or punctured flower has, as yet, been observed ; 
no pollen has in any case been found upon the stigma; yet the ovaries have 
swollen, producing abundance of seed, and Dr. Schoenland, who examined 
them, found the seeds to contain a perfect embryo. The question remains, 
* How is the fertilisation effected ??” We can only suggest that at some 
stage before the buds are fully developed the pollen-tubes begin to grow, 
and find their way to the stigma, thus effecting fertilisation, after which the 
development of the other organs of the flower is arrested, as in the case of 
other cleistogamous flowers, while in the unfertilised flowers they continue 
to develop in the normal way until mature. As regards the plates generally 
it may be said that they will be invaluable as aids to the identification of 
these interesting but difficult plants. Future parts will be awaited with 
interest, and we venture to express the hope that in time most of, if not all, 
the South African species will be represented by a good figure. 
An appendix to the work enumerates thirteen additions to the same 
author's Orchids of the Cape Peninsula, published in 1888, making a total of 
II5 species known from the Cape Peninsula, a tract of land about 40 miles 
long and varying from three to eleven broad—about a fourth larger than 
the Isle of Wight—which is‘a remarkably large number for so small an area. 
The third part devoted to the Orchidee of Martius’s Flora Brasiliensis, 
by Prof. Cogniaux, has appeared, and is devoted to the Pleurothallea—or, 
Tather, to part of that group. It contains four species of Cryptophoranthus, 
Seventeen of Masdevallia, seven of Ph iphon, forty-four of Stelis, two of 
Scaphosepalum, and about half the genus Pleurothallis, which from the 
Synopsis is seen to number 226 species. Lepanthes, Restrepia, and idl 
Meria stand over for the next part. As before, a number of prea = 
included which have not yet been found in Brazil, though it is anticipate 
that some day they may be detected there. Thus, no less than nine of the
