x,C,2 Merrill: Erroneous Credits to Philippine Flora 185 
pelago by the manifestly erroneous labeling of Lobb’s specimens. 
On the other hand, specimens that Lobb certainly collected in 
Luzon have been described as new species and accredited to 
other regions. As an example may be cited Antidesma lob- 
bianum Muell.-Arg., much better A. rostratum var. lobbianum 
Tul., as originally described, which was credited to Java, with 
the citation of Lobb 460, this specimen in the Paris herbarium 
appearing as Javan; in the Kew herbarium the same number of 
Lobb’s collection is labeled Luzon. The species, or variety, has 
never been found in Java,'! but has been collected several times 
in the vicinity of Manila. It is very similar to the Philippine 
Antidesma rostratum Tul., and I believe it to be merely a form 
or variety of Tulasne’s species. It was probably separated from 
Antidesma rostratum by Tulasne merely because A. rostratum 
was Philippine, and the variety lobbianum Tul., was supposed 
by him to have originated in Java. Hydrangea lobbii Max. in 
Mém. Acad. Pétersb. VII 10 (1867) 15 was credited by Maximo- 
wicz to Java on the basis of his specimen of Lobb’s collection 
so labeled; the Kew specimen of the same collection is labeled 
Luzon, and this is certainly correct, as the species is common 
and widely distributed in the mountains of the northern Philip- 
pines, but has never been found outside of the Archipelago. 
Clethra lancifolia Turcez. in Bull. Soc. Nat. Mosc. 36 (1863) 231 
was based on Cuming 855 from Luzon, with the citation of Lobb 
449 from Singapore. Lobb’s specimen was certainly from Lu- 
zon, as the species is quite unknown from Singapore, but is a 
common endemic species in the mountains of the Philippines. 
It is evident that species that are credited to Luzon, Borneo, 
Singapore, or Java, solely on the authority of Lobb’s specimens 
so labeled, should not be adopted as belonging to the floras of 
the respective islands without in each case a critical considera- 
tion of the floras of the other three islands involved. 
While it is, of course, quite impossible to prove absolutely that 
the species enumerated below actually do not occur in the Philip- 
pines, at least there is no botanical material extant, that we know 
certainly to be from the Philippines, representing any species 
of the entire list, except Neptuma oleraceae Lour., Eranthemum 
crenulatum Nees, and Clerodendron villosum Blume. All the 
evidence at present available leads me to exclude all the species 
enumerated below, with these 3 exceptions. The present list of 
species excluded on account of erroneous or insufficient labels
