May 31, 1919] Zingiberaceae of the Sorsogon Peninsula 2971 



Forestry number 4574 collected by Mearns and Hutchinson 

 on mount Malindang, I noticed a big difference, not 

 only in the specimens compared but also a difference 

 in the flower of 4574 when compared with the descrip- 

 tion of Alpinia flabellata Ridl. who writes that the flow- 

 er of his Alpinia flabellata major are the same as in 

 the species. The lip of our specimen is entirely differ- 

 ent than those on the type specimens of Dr. Bidley^s 

 species and variety. 



Alpinia vulcanioa Elm. n. sp. 



Small few stemmed clumps. Stems unequal in length, 

 closely connected and enlarged at the base, averaging 

 2 m. long, ascending and recurved toward the top, 1.5 cm. 

 thick, very pale green and covered with shredded old 

 sheaths, subcompressed toward the top; roots profuse, 

 terete, rigid. 3 to 8 dm. long, yellowish brown, arising 

 from the stem bases. Leaves above the middle or toward 

 the distal end only, submembranous, nearly flat, ascending 

 from the base, otherwise gracefully recurved, pleasing 

 green but lighter beneath, the sharply acuminate tips 

 recurved, glabrous, drying greenish brown, the larger 

 ones 6 dm. long by 8 cm. wide across the middle, edg- 

 es with a faint brownish line, base acute, gradually 

 tapering toward both sides, distinctly petioled, linearly 

 oblong; midvein very stout especially toward the base. 

 stramineus when dry. carinate, sunken above, also gla- 

 brous; lateral nerves faint yet numerous, much ascend- 

 ing, straight; petiole 5 to 7 cm. in length, ascending, 

 green, fluted and stramineus, deeply grooved and com- 

 pressed on the upper side; sheaths tightly folding the 

 stem except at the oblique throat, glabrate, strongly 

 carinate, the narrow margin membranous and reddish 

 brown; ligule similar in texture and color to the sheath 

 margin, adnate and extended from the upper sheath 

 margin along the edges of the basal portion of the pet- 

 iole, 2 to 3 cm. long and lanceolately linear. Inflores- 

 cence terminal, asc^ndingly curved, rigid, 3.5 dm. long, spi- 

 cate though larger ones may be few short branched 

 toward the base, the basal one third fiowerless; rachis 

 5 to 8 mm. thick, terete, pale or yellowish green, gla- 

 brous, flowers scattered along the under or outer side, 

 upon few mm. long stout pedicels which are subtended 

 by short but sharply pointed bracts; floral base obconic, 

 1.33 cm. high and nearly 1 cm. across the truncate apex, 

 thick, isabellinus, composed of the thick transversely 

 imbricated and persistent bracts, usually with 2 flowers
