132 THE ORCHID REVIEW. [JUNE, 1917. 
the plant. To begin with, Hartweg’s plant is not C. caudatum at all,. 
but C. Hartwegii, Rchb. f., a member of the longifolium group, which 
was discovered near Quito, about the year 1842, when Hartweg was 
collecting for the Horticultural Society. To it belongs the great sheathing 
bracts mentioned by Lindley. In fact, Lindley’s woodcut shows a plant. 
of C. caudatum, with the scape of C. Hartwegii, on which are inserted four 
flower of C. caudatum. The corresponding sheet in Lindley’s Herbarium 
shows a flowerless scape of C. Hartwegii, with a drawing of the original 
flower of C. caudatum from Ruiz and Pavon. The bracts in the coloured 
plate, mentioned as mere abortions, are quite normal. There is thus no 
evidence that Hartweg ever met with C. caudatum. It is stated that he 
did not send it home, and as the dried specimens, both in Lindley’s and 
the Kew Herbarium, belong to C. Hartwegii, the evidence seems 
conclusive. The locality ‘‘ Peru” belongs to the dried specimens collected 
by Ruiz and Pavon and by William Lobb. As to where Linden’s plant 
{the one represented in the plate) was collected there is no evidence, but 
‘we suspect it to have been New Grenada, where Linden had a collector at 
about this period, and where Lehmann subsequently collected it. The 
light colour rather recalls the variety Wallisii, but we think the evidence is 
against it being this. Unfortunately no flower was preserved, but the New 
Granadan form agrees well, so far as we can see on comparison. As to 
Warscewicz’s remark that the flowers are very much larger and finer- 
coloured in its native swamps, we believe that this refers to the Central 
American variety, Warscewiczii, to be presently noticed. There is thus no 
evidence of the introduction of the original Peruvian form, which we are 
inclined to think is due to M. Forget. 
We now come to two very distinct local varieties, as they are now 
generally considered. In 1852, Reichenbach described, under the name of 
Cypripedium Warscewiczii (Bot. Zeit., 1852, p. 692) a plant that had been 
collected by the Polish botanical explorer, Warscewicz, on the mountains 
of Chiriqui, Central America. This was ultimately introduced, and after- 
wards figured under the name of C. caudatum roseum (Rev. Hort., 1867, 
p- 133, with plate), a name which very well describes its difference from 
the original form. It soon became generally cultivated, and now bears the 
name of C. caudatum var. Warscewiczii. 
The variety Wallisii, which is characterised by its rather smaller 
flowers and lighter colours, was originally described as Selenipedium 
Wallisii (Rchb. f. Xen. Orch., ii. p. 189, t. 181), from materials obtained 
by Gustav Wallis in Ecuador, gies Lehmann subsequently collected it. 
The latter's specimens are localised as Rio Zamona, at 800-1000 métres. 
The plant collected by Davis at Huanaco, Peru, which was subsequently 
referred here, belongs to typical C. caudatum. R.A.R.
