that Pavetta palawanensis Elm. must be removed from this 
genus; see Tarenna palawanensis Merr., page 471. The descrip- 
tion of Pavetta palawanensis Merr. (non Elm.) cited above is 
typified by Bur. Sci. 326 Bermejos, this specimen thus becoming 
the type of Pavetta phanerophlebia Merr. 
PAVETTA LUZON 1ENSIS (Vid.) comb. nov. 
Webera luzoniensis Vid. Phan. Cuming. Philip. (1885) 119, 179, 
Rev. PI. Vase. Filip. (1886) 152; Merr. in Philip. Journ. Sci. 1 
(1906) Suppl. 133; Elm. Leafl. Philip. Bot. 1 (1906) 40. 
The type of this is Cuming 1323 from Cagayan Province, 
Luzon. It is one of the forms having 5-merous flowers, falling 
in the group that some botanists have placed in Webera. While 
the specimens cited below present some variations from the 
type, they are in most respects fairly uniform and I believe 
all represent Vidal’s species: 
LUZON, Cagayan Province, Adduru 66, 120, 192, 26U: Apayao 
Subprovince, Bur. Sci. 281U6 Fenix: Pangasinan Province, Al- 
berto 29: Nueva Vizcaya Province, Merrill 1U2: Bataan Province,

PAVETTA MEYERI (Elm.) Elm. Leafl. Philip. Bot. 3 (1911) 1015. 
Ixora meyeri Elm. Leafl. Philip. Bot. 1 (1908) 68. 
Webera meyeri Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 133. 
Tarenna meyeri Elm. Leafl. Philip. Bot. 5 (1913) 1898. 
This species is still known only from a single collection, For. 
Bur. 276A Meyer, from Mount Mariveles, Bataan Province, 
Luzon. The flowers are not mature, so that the styles are not 
exserted as is the case with Pavetta in full anthesis. The 
specimen is, however, a typical Pavetta; it cannot possibly be 
referred to Tarenna as the cells are but 1 -ovulate. 
PAVETTA PUBESCENS (Bartl.) comb. nov. 
Stylocoryna pubescens Bartl. ex DC Prodr. 4 (1830) 377. 
Webera sp. Vid. Phan. Cuming. Philip. (1885) 42. 
I have seen two specimens of Haenke’s collection on which 
this species was based, one in the Prague Herbarium, in flower, 
and one in the Herbarium of the Missouri Botanical Garden, in 
bud. Haenke’s specimen was unquestionably from northern 
Luzon, as it is closely matched by several specimens from this
