THE ORCHID REVIEW. 269 
supply of water during the growing season. The flowers are of a pleasing 
shade of orange-scarlet, with a yellow disc to the lip and the column 
tinged with violet-purple. It is a native of Peru, whence it was sent by 
M. Jean N6tzli to Messrs. Linden, L’Horticulture Internationale, Brussels, 
and was named in honour of the introducer (Rolfe in Lindenia, t. 266), 
though from a mistake in the spelling of this gentleman’s name, it was 
at first spelt ‘“‘ Noezliana.”” It received a Botanical Certificate from the 
Royal Horticultural Society on November 11, 1890, but has since greatly 
improved, though it is doubtful if the inflorescence. will develop the free- 
branching habit originally shown. Messrs. Charlesworth, Shuttleworth, 
and Co., Heaton, Bradford, afterwards introduced it from the same 
locality. 
NOMENCLATURE OF CYPRIPEDIUM. 
THE last-issued part of Engler’s Botanische Fahrbucher contains an article by 
Prof. Pfitzer, of Heidelberg, entitled “ Beitrage zur systematic der 
Orchideen,” chiefly in reply to the startling changes in the nomenclature 
of Orchids proposed by Dr. Otto Kuntze. It concludes with some 
criticisms on the classification of the Cypripedium group. It will doubt- 
less be remembered that some years ago this author proposed a system of 
classification based for the most part upon the vegetative organs, and 
among other changes, transferred the tropical species of Cypripedium and 
Selenipedium with coriaceous leaves to a new genus, which he called 
Paphiopedilum. To this, in my Review of the Apostasiee (Fourn. Linn, 
Soc., XXv. p. 215), I objected, on the ground that the new genus possessed 
no difference in floral structure, being based entirely upon the conduplicate 
leaves (by a slip written ‘‘connivent”’), and, moreover, contained species 
just as diverse as the foliose species of Cypripedium and Selenipedium, 
which he retained as distinct genera. 
Prof. Pfitzer now returns to the question (Engl. Bot. Fahrb., xix. p. 31), 
attempting to vindicate his position, and further giving an enumeration of 
the species. Cypripedium is called Cypripedilum, and is limited to the 
hardy foliose species. The section Diphylle is limited to C. japonicum, 
while its allies are transferred to section Foliose. Selenipedium is reduced 
to the three foliose species, which are called Selenipedilum ; while all our 
familiar cultivated species are transferred to Paphiopedilum. Various 
exploded species are resuscitated, as P. Elliottianum, P. Gardineri, P. 
reticulatum, P. dilectum, and others, and thus unnecessarily increase the 
already too numerous synonymy. The latter is a synonym of P. Boxallii, 
which is wrongly enumerated in the group Tessellate, while P. villosum, of 
which the preceding is scarcely more than a variety, is referred to another 
group called Viridia. P. Charlesworthii is included in Tessellate, while its.
