This specimen is unfortunately incomplete, the flowers being in poor con- 

 dition. It is an interesting plant and differs in several points from the 

 normal Hornstedtias but may belong to that genus. 

 Hornstedtia philippinensis Ridley, n. sp. 



Stems 2 m. tall. Leaves oblong lanceolate, caudate, glabrous, narrowed 

 to the base, 10 inches long, 2 inches wide, paler beneath. Ligule bilobed, 

 oblong, obtuse, one-fourth inch long. Inflorescence 2 inches long, bracts 

 thin, lanceolate, ribbed, hairy at the tip, the largest about an inch long. 

 Flowers scarlet, 3 inches long. Bracteole oblong lanceolate, strongly nerved, 

 three-fourths inch long, margins ciliate. Calyx tubvilar, 11 inches long, the 

 trifid lobes acute, one-fourth inch long. Corolla tube 2 inches long, slender, 

 lobes linear oblong, narrow, obtuse, one-fourth inch long. Lip 1 inch long, 

 fleshy, linear oblong, obtuse, entire, narrow. Stamens crestless, one-fourth 

 inch long, apex retuse. Fruit on a peduncle one-half inch long, stout, 

 elliptic, obtuse, 1 inch long, covered with short simple and forked processes. 



Island of Masbate (1704 Clark) ; Davao, Mindanao (416 Copeland). 



This species is remarkable for the fruit which resembles more that of 

 Amomum. Fruit edible, "Tugis." 

 Kolowratia elegans Presl. 



Lamao River, Mount Mariveles, Province of Bataan, Luzon (7.3 Whit- 

 ford) ; 6 to 8 feet high. An unripe fruit over an inch long, glabrous, 

 elliptic, narrowed upwards and terminated by the withered flower is with 

 the specimen. This plant is referred to the genus Alpinia by Schumann, a 

 suggestion I am unable to endorse. 

 Alpinia Haenkei Presl. 



Plant 2 m. tall. Leaves oblong, acuminate, 25 inches long, 5 inches wide, 

 glabrous on both surfaces except on the edges and at the base which are 

 pubescent silky, base narrowed ; petiole 4 inches long, pubescent ; ligule 

 oblong, half an inch long, pubescent. Peduncle stout, 7 inches long, pubes- 

 cent. Bract large, spathaceous, three-fourths of an inch long, scabrid pubes- 

 cent. Calyx spathaceous urn-shaped, cleft on one side, irregularly toothed, 

 as long as the corolla tube, half of an inch long. Corolla tube broad, lobes 

 white silky, broad, oblong, obtuse, white, three-fourths of an inch long, one- 

 fourth inch wide. Lip IJ inches long, broad, apex narrowed (apparently 

 bifid) yellow with purple spots. 



Baco River, Mindoro (4047 Merrill), March, 1905. In very humid forest; 

 fragrant. 



I take this to be Presl's Alpinia Haknkei, which he first referred to A. 

 malaccensis. There is indeed but little diflTerence between the two species. 

 The original A. malaccensis Roscoe is a native of India and does not occur 

 wild in Malacca so far as is knoA^Ti, nor in the Malay archipelago. 

 Alpinia philippinensis Ridley, n. sp. 



Plant 12 feet tall, leaves lanceolate linear, 19 inches long, 2J inches wide, 

 acuminate caudate, hairy on both surfaces, hairs longer and scantier on edge 

 and upper surface; petiole 1 inch long, hairy; ligule bifid, hairy. Raceme 

 2 feet long, rhachis fairly stout, densely rufous hairy with rather bristly 

 white hairs. Pedicels one-half inch long, scattered to base of raceme.
