Type specimen No. 782 (Whitford), Tinuan River, Province of Tayabas 

 (Infanta), Luzon, September 6, 1904. Growing on hilltops at an elevation 

 of about 150 m. Locally known as Calaquimay. Perhaps most closely 

 related to Pandanus conoideus Lam., from the Moluccas. 



GRAMINE^. 



Agrostis elmeri sp. nov. 



A weak, erect, tufted, glabrous, perennial grass about 40 cm. high, 

 with linear, flat leaves, more or less contracted panicles about 20 cm. long, 

 subequal empty glumes and awnless flowering glumes, the palea equaling 

 the glume in length. Culms slender, the nodes glabrous. Sheaths about 

 equaling the internodes, glabrous. Ligule 3 to 4 mm. long, minutely 

 scabrid, entire, obtuse, or slightly lacerate in older specimens. Leaves about 

 10 cm. long, 3 mm. wide, the cauline ones similar in shape and size to 

 the radical. Panicles greenish, the rhachis glabrous, the branches minutely 

 scabrous; branches ascending, subverticillate, 5 to 7 cm. long, the pedicels 

 scabrous, 3 mm. long, filiform, thickened at the base of the spikelet. Empty 

 glumes subequal, lanceolate, acute or slightly acuminate, -2 mm. long, 0.8 

 mm. wide ( when spread ) , the keel scabrous, the margins minutely so. 

 Flowering glume 1.6 mm. long,' acute, awnless, glabrous. Palea equaling 

 the flowering glume. ' Anthers 0.5 mm. long. 



Type specimen No. 6558 (A. D. E. Elmer), Mount Santo Tomas, Province 



of Benguet, Luzon, July 1, 1904. This species grows on the open, grassy 



slopes of the mountain, at an altitude of 2,000 m. and above, forming 



tufts, the weak stems often more or less reclining. Agrostis elmeri is 



according to Hackel, to whom specimens were sent, very closely related to 



Agrostis perennaiis Tuck., a species of the northeastern United States. No 



species of the genus has previously been reported from the Philippines. 



Dinochloa diffusa (Blanco) Merrill, Govt. Lab. Publ. 27:93. 1905. (Bam- 



lusa diffusa Blanco, Fl. Filip. ed. 1, 289; ed. 2, 187; ed. 3, 1:334. 



Dinochloa dielisiana Pilger in Perkins Frag. Fl. Philip. 149: 1904; 



at least in part, Nos. 1408 and 2550 Merrill. ) 



This species was reduced by Fernandez-Villar 1 to Schizostachyum acuti- 

 //onnn Munro, which is apparently an error. The species here considered to 

 represent Blanco's Bambusa diffusa is very abundant throughout the region 

 from which Blanco received his material, and as it apparently produces 

 flowers at least once a year it is very doubtful whether Blanco over- 

 looked it. On account of its diffuse and often somewhat spiny branches it 

 is much used by the natives for making rough brush fences about their 

 clearings as noted by Blanco. It is represented by the following specimens, 

 nil from the Island of Luzon: Province of Bataan, Lamao River, Mount 

 Mariveles: No. 2550 (Merrill), June, 1903; No. 3297 (Merrill), October, 

 1903; No. 519 (Whitford), July, 1904; No. 1261 (Forestry Bureau), 

 collected by Borden, July, 1904. Province of Zambales, No. 388 (Forestry 

 Bureau), collected by Maule, March, 1904. Province of Pampanga, Arayat,
