THE ORCHID REVIEW. 45 
violet colour. It is said to be ‘‘a splendid thing,” but seems still to be 
known only from description. 
5- P. Wattisii (Lind. & Rchb. f. in Gard. Chron., 1869, p. 1710) was 
introduced by M. G. Wallis, “no doubt from Western New Grenada or 
Ecuador,” and flowered with M. Linden, in 1869. A coloured figure in 
Flore des Serres, t. 1828, shows the flower to be cream white, with the apex 
of the sepals, petals, and lip violet-purple. 
P. Dayana (Rchb. f. in Gard. Chron., 1872, p. 1618) is a New 
Grenadan species which was discovered by M. Gustav Wallis, and flowered 
in the collection of J. Day, Esq., at Tottenham, in 1872. It is very variable 
in colour. The original form had milk-white flowers with green tips to the 
sepals, and the crest purple-violet. Var. candidula is quite white; var. 
thodacra (Bot. M ag., t. 6214) has purple tips to the sepals and petals, and 
the disc of the lip also reddish purple ; while var. splendens has still more 
and darker colour on the same parts. 
7- P. Ruckertana (Rchb. f. in Gard. Chron., 1885, xxiv, p. 424) was 
described as “‘ much in the way of P. Dayana, but entirely distinct in the 
very acute undulate sepals and petals, which appear to be fond of twisting, 
Which produces an entirely novel appearance.” Colour white with green 
apex and a large, light purple area near it; lip purple, with a white callus, 
and some yellow on the side lobes. It was imported by Messrs. Linden, 
and flowered in the collection of Mr. Rucker-Jenison, of Flotbeck Park, 
‘Hamburg, in 1885. 
8. P. BELLA (Rchb. f. in Gard. Chron., 1878, ix, p. 492) was described 
as a grand beauty, having light whitish violet sepals and petals, with a very 
broad band of the darkest purplish violet at the apex, and a light whitish 
yellow lip, with a violet blotch at the apex. Its history is that it was sent 
to the author by Mr. Harry Veitch, and ‘may be Neo-Grenadan.” 
Reichenbach, while placing it between P. Roezlii and Dayana, added— 
“We have had nothing comparable in colour, excepting Bollea ccelestis. I 
— havea melancholy fear it is a mule between this and some Pescatorea. 
As it is, we must wait and observe—laboremus; there may come the day 
when we, or those who will come afterwacds, may get the necessary light.” 
9. P. Rogezii (Rchb. f. in Gard. Chron., 1874, i, p- 755), is a nafive of 
Ecuador, collected by M. Roezl, and was originally described from dried 
Specimens; afterwards flowering in the collection of Sir Trevor Lawrence, in 
December, 1876. It is allied to P. Dayana, and has cream-coloured flowers, 
with large violet blotches at the apex of the sepals and petals, and a lip of 
the latter colour. P. euglossa (Rchb. f. in Gard. Chron,, 1876, vi, p- 808), 
Was discovered by M. Edward Klaboch, who thought it identical with P. 
Roezlii, though Reichenbach, in 1876, pronounced it to be very distinct in 
the structure of the lip. In 188z, however, he mentioned a P. Roezlii var.
