MARTELLI. 
§ SUSSEA ? 
(13) Pandanus pallidus Merr. in Govt. Lab. Publ. 29 (1905) 5. 
Luzon, Province of Benguet, Baguio, Elmer 581/0, March, 1904. 
At first Sight this species seems to belong to the section & lussea, but a careful 
study of the disposition of the locules as well as a section of the phalanges, 
leaves me somewhat uncertain about this classification. Perhaps it may be a 
type of a new section, but I require complete material and especially the male 
flowers to allow me to solve the question. All the species of 8 ussea hitherto 
known grow in Africa. 
§ BRYANTIA. 
(14) Pandanus gracilis Blanco FI. Filip. (1837) 778; ed. 3, 3: 182, t. 1/1/6 ; 
Merrill in Govt, Lab. Publ. 27 (1905) 89. 
Pandanus Whitfordii Merrill 1. c. 17 (1904) 7. 
Luzon, Province of Bataan, Mount Mariveles, Whit ford 50, 351, 507; For. Bur. 
291/4 Borden: Province of Rizal, Montalban, Loher 1573 (in Herb. Kew). Min- 
danao. District of Davao, Baroring River, Copeland 11/37, October. 1904. 
Mr. Merrill has already recognized the similarity between his Pandanus Whit- 
fordii and Pandanus gracilis Blanco, and placed the former in the section Sussea, 
but it is better perhaps to ascribe it to Bryantia. 
(15) Pandanus paloensis Elmer, Leafl. Philip. Bot. 1 (1906) 75. 
Leyte, Palo, Elmer 731/3, January, 1906, very common in the shrubby forests 
of the low hills and in the Barringtonia formation near the seashore and along 
the larger rivers. 
This species seems to me to be closely allied to Pandanus gracilis Blanco and 
perhaps not sufficiently distinct, or only a variety of Blanco’s species. To de- 
termine its validity, well prepared and complete specimens are necessary.

Sci.), March, 1905, in high forests at the top of the mountain at 900 m alt. 
(IS) Pandanus lateralis Martelli sp. nov. 
Prostratus vel erectus, 1-6 m altus. Folia ad extremitates ramorum

usque ad medium auguste plicato-eanaliculata, dein plicato-expansa, 
apice sensim attenuata, acuta, in pagina inferior! minutissime longitu- 
dinaliter venulosa, snperne nitida, plicis lateralibus apicem versus, longo 
tractu, minute acuteque aculeatis; marginibus, ima basi excepta, acute 
serratis; costa media, in parte apieali, subtiliter prominula, acuta, spinis 
sparsis minutissimis serrulata; in parte inferiori evanida et inermi ; in
