Leaflets of Philippine Botany 



[Vol. VII I, Art. 119 



Field-note for 15900: — Tufts in wet gravelly earth 

 of very steep densely wooded ravines at 1000 feet alti- 

 tude. Stems few to several, bulbose at the base, ascend- 

 ing from the ground, otherwise much recurved, .5 inch 

 thick, terete, dark green, 5 to 8 feet long, the upper 

 two thirds leaf bearing; blades darker green above, flat 

 but wavy edges, tips much recurved, coriaceous, reduced 

 and scattering toward the base; flower cluster from the 

 rhizome near the stem base; stalk subcompressed, red, 

 its fleshy bracts whitish; flowers several or more, sue 

 culent, the boot reddish tinged; corolla yellowish white 

 or white and with a yellow center and purplish spotted, 

 the lateral appendages of the staminode broad; fruit 

 nearly 1 inch long, purplish black, prickly. 



Represented by numbers 15614 and 15900, Elmer, Irosin 

 (Mt. Bulusan), Province of Sorsogon, Luzon, December 

 1915, and April 1916 respectively. 



In May, 1904 I collected at Baguio flowering clus- 

 ters of a Zingiberaceous plant under number 6284 and upon 

 which Dr. Ridley founded his species Amomum propinquum. 

 A month earlier Dr. Copeland also collected typical flow- 

 ering specimens without leaves at Davao under his num- 

 ber 843. Since then no flowering specimens were col- 

 lected. In the genus covers of the Bureau of Science 

 are two leafy specimens determined by Ridley as Amomum 

 propinquum— nAme\y 2866 Williams from Davao and 7664 

 Elmer from Lucban. Neither of these sheets are Amomum 

 propinquum Ridl., but rather represent Amomum muricarpum 

 Elm. Under the same covers are eight other sheets with 

 flowers only, and which appear to be a saprophytic species 

 of Orobanchaceae. The type sheet of Hornstedtia philippinensis 

 Ridl. or Clark 1704 from Masbate contains the fruit of 

 Amomum propinquum Ridl. Hornstedtia propinqua (Ridl.) Elm. 

 has different flowers, narrower leaves and entirely too 

 long stipules to be classed with Hornstedtia muricarpa (Elm.) 

 Elm. n. comb. (Amomum. muricarpum Elm. Leaf Philip Bot 

 vui, 2896, 1915). 



Hornstedtia philippinensis Ridl. 



Field- note:— Rank and scattering perennials, in wet 

 more or less compact soil of light woods at 750 feet 

 altitude facing the Pacific ocean. Rhizome long, few to 

 several from each of the bulbose stem bases, terete, hor 

 izontal, tough, rebranched, .5 to .75 inch thick, yel- 

 lowish; stem erect, terete, dull green, with a much 

 enlarged base, mostly above ground, 15 feet long, the 

 basal one half leafless, the upper part ascending or even
