apex. Corolla-tube very slender, 2.5 cm long, about 1 mm in diameter, 
the antheriferous portion near the apex slightly inflated and about 2 mmi 
in diameter, this portion also densely bearded inside, the outside with 
scattered, short hairs, the lobes linear-lanceolate, 9 to 10 mm long, 2 mm 
wide at the base, gradually narrowed upward to the slenderly acuminate 
apex, more or less pubescent. Anthers 4 to 5 mm long. Style 4 to 5 mm 
long, cleft one-third to one-half into two arms. The persistent leaf-like, 
accrescent calyx-lobe is white, elliptic-ovate, ovate, or oblong-ovate, 
membranaceous, 6 to 9 em long, 3 to 5.5 cm wide, 5- to Y-nerved from 
the base, the nerves more or less hirsute, the reticulations lax, the apex 
shortly and sharply acuminate, the base acute or rounded, the stipe about 
2 am long. Fruit fleshy, narrowly obovoid, about 1.3 mm long, black 
when dry, with few, long, scattered hairs, the calyx-lobes, other than the 
accrescent one, early deciduous.

A species well characterized by its long, slender, corolla-tubes which are white 
instead of yellow, differing in these characters from all Philippine species known 
to me.

Mussaenda frondosa Auct. Philip., non Linn. 
There are at present about 60 sheets in the herbarium of the Bureau of Science 
that are apparently referable to a single variable species, or perhaps to several 
closely allied ones. The material has been identified at various times, some 
specimens as Mussaenda frondosa Linn., some as M. grandiflora Rolfe, and some as 
M. glabra Vahl. Rolfe in 1884 stated that he had seen no Mussaenda frondosa 
Linn., from the Philippines, and I can only agree with him in considering that 
the typical form of Linneus’ species does not extend to the Archipelago. The 
type of Mussaenda frondosa Linn., was from Ceylon, and the Director of the 
Botanic Garden at Peradeniya has kindly supplied me with a full series of 
Specimens representing the Ceylon plant, presumably some of which are typical 
Mussaenda frondosa Linn. None of this Ceylon material matches any of our 
Philippine specimens. Mr. Rolfe transferred Calycophyllum grandiflorum Meyen 
to Mussaenda, to supply a specific name for the Philippine plant, but overlooked 
the fact that the above specific name was invalidated in Mussaenda by the earlier 
M. grandiflora Benth. I have accordingly adopted for the Philippine species the 
name Mussaenda philippica A. Rich., which was based on material secured in the 
Philippines by Perrottet. Whether or not it is the oldest valid name for the 
species, I am unable to determine at the present time; some of our Philippine 
specimens apparently closely match some Javan and Caroline Islands material 
distributed as M. frondosa Linn., and M. glabra Vahl. Mussaenda philippica 
A. Rich. is an erect shrub or small tree, not at all scandent, and as at present 
interpreted, extends from northern Luzon to southern Mindanao, and will probably 
be found to extend to other parts of Malaya.
