MARY STRONG CLEMENS, I.

{From the Botanical Section of the Biological Lahoratory, Bureau of Science, 
Manila, P. I.) 
Troin December, 1905, to October, .1907, Cliaplain Joseph Clemens of 
the Seventeenth United States Infantry, accompanied by liis wife, was 
stationed at Camp Keithley, Lake Lanao, Mindanao, and during this time 
Mrs. Clemens made extensive botanical collections which were forwarded 
from time to time to this herbarium for study. In the tAvo years during 
which collections, were made, somewhat over 1,200 numbers of plants 
were sent to Manila, besides a very extensive sup2;)lemcntary collection 
of unnumbered material. 
Lake Lanao is located at an altitude of about 7G0 meters above the 
sea, and Camp Keitliley is situated near the lake on the ridge- between it 
and the Suhi Sea, the highest point on the reservation being about 815 
meters above sea level. The region is subject to heavy rainfall, and 
during parts of the year fogs are ver^j^ prevalent, so that the humidity 
is relatively higli. The district was entirely unexplored botanically, 
and the collection, as was to be expected, has shown an unusually 
liigh percentage of novelties, containing many genera hitherto unknown 
from the Philippines, several apparently undoscribed genera, many species 
new to tlie Arcliipelago, and a great number of undescribed species, while 
the range of many plants, previously known only froui Luzon, has been 
extended to Mindanao. A number of novelties from this collection have 
been included in my previous papers, among them several new species, as 
well as genera and species new to the Philippines. The material still 
contained so much of interest that it was thought advisable to prepare 
and publish a series of two or three papers, for the greater part based 
on this collection. 
The Lake Lanao region, politically, is one of the most turbulent 
districts in the Philippines, and has been under firm control during the 
recent years of American occupation only, and after several campaigns 
against the fanatical Moros who inhabit the region. Spanish authority 
was only nominal before the year 1898, while even at the present date 
the district can not be considered a safe one for the traveler. Minor
