ILLUSTRATIONS. 
On the left is a large tree of Shorea polysperma (tanguili), on 
the right in background is Hugenia glaucicalyx. Other smaller 
trees are Cinnamomum mercadoi and Baccaurea tetrandra. 
Rattans (Calamus) are also present. Dipterocarpus-Shorca 
formation. 
Narrow ridge between two ravines on the slopes of the main 
ridge. See Table XIX, Plot F. On the left is a tree of 
Cryteronia cumingii, in the center is Hopea acuminata (dalin- 
dingan), and on the left is Quercus sp. Young trees of 
Ardisia, Cinnamomum, Hopea, and Cryteronia are present. 
A very unstable habitat in the Shorea-Plectronia formation. 
A side ravine near the habitat shown in Plate XXIX. The 
large fern is a Dennstaedtia species. The habitat is a newly 
formed one well protected from strong insolation. 
View of the eroding bank of the Lamao River at 100 meters 
altitude. At the base Nephrodium philippinense, above this 
the aroid Schizmatoglottis rupestris. Freycinetia ensifolia 
is on the left. Begonia rhombicarpa is also present. Com- 
pare with Plate XXXII. Anisoptera-Strombosia formation. 
Side ravine in Shorea-Plectronia formation. Altitude about 600 
meters. On the face of the damp rocks Gymnopteris incon- 
stans is abundant, with a small species of Selaginella. In the 
center is Schizmatoglottis rupestris, to the right is Polybotrya 
appendiculata, and above is Freycinetia ensifolia. Compare 
with Plate XXXI. 
View in the bed of the cafion of the Lamao River. On the left 
is a dry rock mostly showing lichens, on the right there is 
more or less seepage from the rock. Here are found NSchiz- 
matoglottis rupestris and the delicate urticaceous shrub 
Elatostema whitfordii. On a tree in the background is 
shown a specimen of the bird’s-nest fern, Asplenium nidus. 
View of the “elfin” forest at 920 meters’ altitude. Trees are 
Eugenia acuminatissima var. parva, Machilus philippinensis, 
Canarium villosum, Hacoecaria philippinensis, Clethra lanci- 
folia, and others, HEugenia-Vaccinium formation. 
View of rock outcrop. See Plot B, Table XXIII. Note the 
manner in which the roots of a Ficus sp. hold the rocks. Tree 
in center is Hugenia acuminatissima. Polypodium meyenia- 
num on the rocks above, Note lichens on the rocks. Hugenia- 
Vaccinium formation, 
View on the ridge at 1,100 meters. The grass-like orchid Acori- 
dium tenellum is growing on Eugenia congesta. Above 
Acoridium is another orchid, Cestichis sp.; on the left below 
is a young specimen of the fern Cyathea caudata. Note 
mosses and liverworts. MWugenia-Vaccinium formation.
