ad AMES. 
Phreatia Mearnsii is nearly related to P. aristulifera Ames and P. 
Vanoverberghii Ames, but differs from them in details of the flowers. The 
petals of P. Mearnsii are not unguiculate nor in any sense rhombic in 
outline. 
Phreatia (§ Euphreatia) Ramosii sp. nov. 
Planta parvula. Folia linearia. Pedunculus folio longitudine 
fere aequalis vel longior. Flores albi. Sepala lateralia trian- 
gulari-lanceolata, obtusa. Sepalum superius ovatum, obtusum. 
Petala ovata, ad apicem rotundata. Labellum oblanceolatum vel 
obovatum. Mentum obtusum. 
In habit similar to Phreatia myosurus (Forst.) Ames. 
Plants about 1 dm tall. Leaves linear, asymmetrical at the tip, 4 
to 9 cm long, up to 5 mm wide, spreading, equaling the peduncle 
or slightly shorter. Peduncle slender, 5 to 10 cm long, bracts 
sheathing, about 5 mm long, acuminate, aristate. Raceme 2 
to 4 em long, about 7 mm through when the flowers are open. 
Flowers white, diminutive, about 1 mm apart. Floral bracts 
rounded, prolonged at the tip, aristate, 3 mm long, aristate tip 
1.5 mm long. Pedicel and ovary 3 mm long. Lateral sepals 
about 2 mm long (forming a blunt mentum 0.5 mm long), 
triangular-lanceolate, obtuse. Upper sepal 1.75 mm long, 
broadly ovate, obtuse. Petals ovate, rounded at the tip, 1.5 mm 
long, about 1 mm wide. Labellum 2.5 mm long, oblanceolate or 
obovate, about 1 mm wide at the middle. Column simple. 
LUZON, Province of Abra, Maximo Ramos, Bur. Sci. 7140, February 8, 
1909. Epiphyte, found on small trees in forests. 
Phreatia sulcata J. J. Smith. 
In a preceding paper * I described a new species from the Philippines as 
P. bracteata. An examination of additional material from Luzon convinces 
me that the specimens cited under P. bracteata are conspecific with P. 
sulcata J. J. Smith. A series of specimens from Bontoc Subprovince, Luzon, 
collected in June, 1911, by Father M. Vanoverbergh, No. 1289, are most 
certainly referable to Phreatia sulcata and compare well with specimens 
from Sumatra. 
Phreatia (§ Euphreatia) Vanoverberghii sp. nov. 
Habitu P. densiflorae (Bl.) Lindl. haud dissimilis sed in foliis 
angustior et in racemo gracilior. Folia linearia. Racemus 
densiflorus. Bracteae inflorescentiae aristatae. Sepala late- 
ralia ovata. Sepalum superius ovatum, obtusum, concavum. 
Petala unguiculata, rhombico-spathulata. Labellum unguicu- 
latum, ad basim cuneatum, super medium dilatatum, ad apicem 
in laminam subrhombicum dilatatum.
