united petals, forming a cylindric tube quite closed at the apex by an 
appendag'e from each corolla-lobe uniting to form a conical body at the 
mouth, the four free spreading lobes being broad and very short. This 
description is true of the original specimens, but quite mature flowers on 
recently collected material shows them not to be cleistogamous, and the 
corolla to be composed of four entirely free petals, and hence the species 
being referable to Loranthus, § Heteranthus. 
Specimens from Malamey, Bontoc Subprovince, Luzon, collected by 
Father Vanoverbergh, in June, 1911, (no. 1293) match the type of Cleis- 
toloranthus verticillatus in all respects except that some of the flowers 
are quite mature and open. The original description of the species must 
be emended as follows: 
Inflorescence solitary or fascicled at the nodes, the flowers in 
umbellately disposed triads, or by reduction, in diads. Calyx 
2.5 to 2.8 mm long. Petals 4, free, valvate, 1.6 cm long, about 
1.7 mm wide, the reflexed part above the insertion of the stamen 
narrowly oblong, 5 mm long, about 2 mm wide, each petal with 
a somewhat triangular, thick appendage on the inner surface 
near the apex, the four appendages forming a conical body that 
closes the corolla in bud, the petals in bud with a spreading, 
2 to 2.3 mm broad, short, truncate tip. Stamens 4 mm long, 
erect; filaments 2.5 mm long; anthers 1.5 mm long, continuous 
with the filaments and of the same diameter. 
In spite of the reduction of Cleistoloranthus to Loranthus the species 
is a very distinct one in the latter genus, characterized by the peculiarly 
appendaged petals. In the generally accepted interpretations of the genera 
of Loranthaceae, Cleistoloranthus cannot be considered to be generically 
distinct from Loranthus, but with any treatment of genera approaching that 
proposed by Van Tieghem, it would probably rank as distinct as most 
of the genera indicated by that author. 
Unfortunately the specific name originally used by me is not valid in 
Loranthus, hence the necessity of coining a new specific name under the 
latter genus.
