BOTANICAL NOTES. 187 
To this should be added about 30 numbers of pahns and oi-diids, wliich 
will show similar proportions between duplicated and single collections, 
with a small balance in favor of the later months. The mosses, 28 num- 
bers, and the fungi probably contain little of interest. On the other 
hand, the lichens are expected to add materially to tlie list of I'liilippine 
species. In spite of the disparity in numbers, Mr. McGregor's collection 
was the more interesting of the two. 
As practically all belong to the Bureau of Science series, tliey will be 
cited by number only, except in the case of new species. Mr. McGregor's 
numbers are from 10210 to 10574 and 10761 to 10783, mine are U<i)2, 
G831 to 7000, 9001 to 9308, and 9592 to 9597. 
The island is peculiarly rich in epiphyllous hepatics and lichens, the 
former much the more abundant in August, the latter forming a greater 
percentage later in the year. This feature had been noted by Mr. 
J. B. Leiberg, who had previously visited the island. They occur at all 
elevations, but are somewhat most abundant just within the outer frmge 
of vegetation along the coast. They are practically always confined to 
the upper surface of mature leaves, and in the humid atmosphere of 
PoliUo seem to lu^^•e no difficulty in reaching the fruiting stage withm 
such a period as the length of the life of the leaf will permit. As yet, 
the detenni nations of the lichens have not been received, but the hepatics 
have yielded a high percentage of novelties. 
On the other hand, but one genus of flowering plants was obtamed 
which was not previously recorded from the Philippines, and it has_ since 
been found bv two collectors on other islands. There are herein indicated 
as endemic to Polillo only 1-1 species of flowering plants, to which a 
very few may subsequently be added where the material is m the hanas 
of specialists, or is insufficient for certain determination, ^one of tue 
ferns are endemic, and with hardly an exception, they are of wide distri- 
bution. In the enumeration of the species, those that are known to be 
of general or wide distribution in the Philippines are merely hst«L 
However, when the species has previously l)een collected on but few 
occasions, or when the collections, however numerous, st«m to lia%e 
confined to definite regions, tlie range is given.
