THE ORCHID REVIEW. 135 
Agusan, but not crossing that river, P. Aphrodite growsin great abundance, 
and amongst them in the Bahia de Iligana singular variety of P. Aphrodite, 
with flowers more richly marked with yellow, and the plants are generally 
found growing in clumps together. The same island is also the home of 
P. Stuartiana, and we may give the valleys around the lagoon of Meinit 
as their favourite haunt. This lagoon lies at the north-east point of 
Mindanao at an elevation of a few hundred feet above sea-level, having its 
source in the very centre of acrater. P. Stuartiana is also to be found in 
great profusion in the very humid valley of the River Agusan, far into the. 
interior of Mindanao until reaching the rivers flowing south, where some 
strayed P. Sanderiana may be found; hence natural. mules between them 
have already appeared. So far, Mindanao, which in extent is the second of 
- the archipelago, is the richest in species, but a great part of it is not searched 
yet, and there can be no doubt that some new species may yet appear. 
P. Aphrodite grows all over the Philippine Islands, indeed, very few are 
entirely destitute of them, yet its cradle may be traced to the central part 
of Luzon, which is the greatest of the 100 Islands, and lies 300 miles north 
of Mindanao. The central part of Luzon, on the Pacific coast, and a few 
adjacent islands, are the only places where P. Schilleriana is to be found 
growing, and where it occupies amongst its congeners the smallest area, 
and distant from the home of P. Sanderiana, about 350 miles. The latter 
is considered to be a natural cross between P. Aphrodite and P. Schilleriana, 
which it maybe botanically, but it seems to be too far off from at least one 
of its supposed parents for this to be likely. The several groups of volcanic 
islands connecting the Philippine Islands with Borneo, although included 
in the archipelago, yet, judged by their flora and fauna, more belong to 
Borneo ; but here is found the link connecting the Phalznopsis of Borneo 
with those of Java. In the Tawi-Tawi group a form of P. Aphrodite 
grows, and in the island of Palawan the true P: amabilis (grandiflora) 
is found. From these islands a straight line down to Java may be traced, 
around which the different forms of P. amabilis are found. 
It is interesting and instructive to have such a complete outline of the 
distribution of Euphal&nopsis in the Philippines, as it helps us to understand 
which are local forms, and’which natural hybrids, occurring where the 
_ others grow intermixed, and P. Sanderiana must be included among the 
former. The silver grey-leaved form we do not recognize—if, indeed, it has 
been introduced to cultivation—and the natural hybrids which occur with 
it do not appear to have been named, nor yet those mentioned between 
P. Stuartiana and P. Sanderiana. 
It will be observed that the section Euphalenopsis is largely certs a 
__ trated in the Philippines, the single exception being the original P. amabilis, 
Usually known in gardens as P. grandiflora, and this occurs also in Palawan.
