Mr. Lyon says that the flowers are very persistent. According to his notes 
the anterior surface of the column and the lip are rich-purple, otherwise the 
perianth is light-rosy-purple, each segment marked with seven well defined lines, 
those on the lip continuous or uninterrupted, those on the sepals and petals 
broken or formed by dots. The leaves are mottled gray and green and are almost 
identically like those of Phalaenopsis 8 chiller ianaP in coloration. 
In addition to Mr. Lyon’s specimen I have studied three others from the Philip- 
pines which 1 do not hesitate to refer to P. IAndenii. Two of these are in the 
herbarium of the Bureau of Science, the third in the herbarium of the New York 
Botanical Garden. All of these were collected in Benguet Province, Luzon. The 
specimen in the New York Botanical Garden collection has larger flowers than the 
others, these being about 3 cm across, with the rotund apical lobe of the lip 
about 1.3 cm long by 1.2 cm wide. The tip of the lip is in no way divided and 
is not at all in agreement with the lip of P. Veitchiana as represented in plate 213 
of the Floral Magazine. Until more material has been studied it seems best to 
adopt Mr. Lolier’s name for this Phalaenopsis. The specimens in the herbarium 
of the Bureau of Science have a branched inflorescence not unlike that of Ionopsis 
utricularioides Lindl. in general aspect, although much stouter. In Orchis ( 1 : 82, 
fig. 37) this species has been very fully illustrated. The analysis of the flowers 
is very detailed.

In Orchidaceae 2: 249, I listed this species, basing my conclusions on a specimen 
collected by the Rev. R. F. Black in Mindanao. This specimen was fragmentary 
and my identification was in a way provisional. Another specimen has come 
to hand from W. S. Lyon which is undoubtedly A. Lawrenceae. The flowers are 
large, about 2.5 cm in diameter and very ornamental. Unfortunately Mr. Lyon 
forgot the exact locality from which he obtained Iris specimens which flowered 
in his garden at Manila.

This species has been collected in Rizal Province by D. LeRoy Topping who 
found specimens in July, 1908. The type was discovered by J. B. Leiberg on 
Mount Mariveles in 1904. One of the specimens found by Topping shows an 
interesting variation from the type in its larger leaves which measure nearly 1 
dm in length and 4-5 cm in width. On this luxuriant form the flowers are in a 
dense raceme, about 20 in number.
