Unfortunately Tournefort added to his genus a yellow- 
flowered Iberian species of Cistanche. This misappre- 
hension might have been of small account had not 
Linnaeus, half a century later, placed Tournefort’s genus 
in Lathraea, as L. Phaelypaea, including in his species so 
named both the Phelipaea and the Cistanche, and, to make 
matters worse, treating the red-flowered Phelipaca as a 
mere variety of the yellow-flowered Cistanche. The 
extraordinary degree of confusion which resulted from 
this treatment it took nearly a century and a half to 
clear up; the story has been lucidly told by Dr. Stapf 
in the Kew Bulletin for 1915. In the meantime it is 
sufficient to remark that the name Anoplanthus which 
has been used for this genus is a needless innovation and 
that, so far as is known, there are but three species of 
Phelipaea, the species discovered by Tournefort, which 
Desfontaines named P. Tournefortii; the subject of our 
plate, which Lambert named P. foliata; and a third 
species, P. Boissieri, a description of which is to be found 
in Dr. Stapf’s article in the Kew Bulletin. The original 
species has been repeatedly collected in Armenia and 
occurs also in Kurdistan. The one now figured was first 
met with near Tiflis by Giildenstedt and in the northern 
foothills of the Caucasus and in Daghestan and Shirwan 
by Marshal von Bieberstein. It has since been collected 
in various localities on both sides of the Caucasus and in 
the southern Crimea. The area of the genus extends to 
North Syria, through Southern Asia Minor as far as 
Caria, and eastwards to Tabriz. The host-plant of 
P., foliata, so far as is known, is always Centaurea dealbata ; 
P. Tournefortii has been collected as a parasite affecting 
Pyrethrum myriophyllum. 
The plants on which our figure has been based 
were grown at Kew from seeds received from the 
Botanic Garden, Tiflis, in 1911. In this case the host- 
plant was Centaurea dealbata. The seeds of host and 
parasite were sown together in a pot, but only the 
Centaurea came up. Later in 1911 the Centaurea was 
planted in the Rock Garden, where it grew alone until, 
in May, 1914, seven stems of the Phelipaea, each bearing 
a solitary flower-bud, made their appearance, the first 
bud to open doing so in the middle of the month. It is
