GESNERIACEAE. 
Two species were collected, and ar,e in the hands of a specialist for determina- 
tion, a Cyrtandra, 10257, and a Trichosporum, 6862. 
ACANTHACEAE. 
Hemigraphis strigosa (Nees) F.-Vill. Noviss. App. (1880) 153. 
This, or an extremely close ally is represented by 6995, the distribution of 
the species, with the same qualification, being Bontoc, Laguna, Masbate, Negros, 
Mindoro, Mindanao. 
Staurogyne debilis (Anders.) C. B. Clarke ex Merr. in Philip. Journ. Sci. 
2 (1907) Bot. 302. 
Represented by 9008; other distribution Cagayan, Benguet, Tayabas, Rizal, 
Negros, Mindoro, Mindanao. 
Other, species : Acanthus ilicifolius Linn., 6961: Blechum brownei A. Juss.,

Willdenow’s and Bartling’s types are extant: of the former we possess a carbon 
impression, of the latter fragments, both secured by Mr. Merrill, who was further 
able to compare them with more recent collections. Both were obtained by the 
same expedition, almost certainly by the same collector, and it is highly probable 
that they are parts of a single collection. Of Meyen’s type, we also have a 
carbon impression, with notes, and it seems to differ only slightly from the older 
species, and then in pubescence. Taken in conjunction with numerous recent 
collections, including 6832, from Polillo, it does not seem possible to maintain 
it as a distinct species. The alliance is unquestionably with H. congesta R. Br., 
but it differs from the only Indian specimen of the latter which we possess, 
Dr. Prain’s collector 57, Andaman Islands, by the thinner leaves with less con- 
spicuous and more arched venation. It has a rather wide Philippine distribution. 
Hydnophytum formicarum Jack in Trans. Linn. Soc. 14 (1823) 124. 
Represented by 9084; other distribution Tayabas, Mindoro, Mindanao, Borneo, 
Java, Sumatra, Andaman . Islands, Malay Peninsula. It may be worth adding 
that although the stem-bases were of large size and characteristically excavated, 
the few ants within were most peaceably disposed. 
Ixora inaequifolia sp. nov. 
Ixorae auriculatae Elmer affinis; sed differt stipulis brevioribus et 
foliis lieterophyllis, oppositis similibus sed parium diflerentium valde 
inaequimagnis, aliis oblanceolatis/ 12 usque ad 20 cm longis, ceteris 
ellipticis, usque ad . 3 cm longis.
