JjUZON, Province of Benguet, Biieil Kiver (4288 Merrill) November 14, 11105, 
altitude 1,200 m. 
Thi.s species was reported from tlie Philippines by F.-Villar, who states that 
he saw living specimens in Luzon and Panay. 1 have never seen specimens of 
this grass from regions at low elevations in the Philippines, and it is possible 
that F.-Villar’s record was based on an erroneous identification. Poa annua was 
found along the new Benguet road near some of the construction camps, the 
seeds undoubtedly having been introduced in American hay, used for food for 
the horses and ninles utilized in the construction work. It was well established, 
and will undoubtedly persist. 
Among other weedy plants collected on the same trip which were certainly 
introduced by the same means are TrifoUum pratense Linn., T. repens Linn., 
Cerastium. vidgatum, Linn., Hpergula arvensis Linn., Rumex acetoselhi Linn., and 
Rumex crispus Linn. All of these plants were found in cultivated places or in 
waste lands near construction camps, and some of them will undoubtedly persist. 
With the exception of Rumex acetoseUa Linn., none of the above species have 
])i'eviously been reported from the Philippines. Trifolium pratense Linn., has also 
been collected in Mindanao, Camp Keithley (Mrs. Clemens), April, 1000.

No species of this small genus has previously been discovered in the Philip- 
pines, the abovm specimen agreeing perfectly with authentic material of Joinvillea 
malayana in the Herbarium of this Bureau, received from the Botanic Garden, 
Singapore, collected at Perak. The species Avas described from material collected 
in Perak and Selangor, Malayan Peninsula, and Mount IMatang, Sarawak, .British 
North Borneo. 
As noted by Ridley, this form is most closely related to one of the ITaAvaiian 
si>ecies, there being two of the genus known from Hawaii, and one from New 
Caledonia. For parallel distribution Ridley cites only the genus Gyrtandra of 
the Qesneriacece, which reaches its maximum development in the Sandwich 
Islands, extending to the Malayan Ai’chi|)elago and Peninsula. For the Philip- 
pines a ])arallel case of distribution is represented by Tetraplasandra philip- 
pinensis Mer. of the Araliucece (see p. 219). In this very characteristic genus, 
one species is known from the Island of Palawan in the Philippines, one from New 
Guinea, one from Celebes, and six from the HaAvaiian Islands. Another case is 
represented by the genus Sclvistostege Hillebr., of the Polypodiacece, of its three 
knoAvn species, one being from Hawaii and tAVo from the Island of Mindanao, 
southern Philippines.® Rolfe“ cites Asplenium. persicifoliuni J. Sm.. as being 
confined to the Philippines and liavvaii, but this species is apparently endemic 
in the Philippines, as Hillebrand“ considers the Hawaiian form distinct from 
A. persicifolium.
