66 MISS L. S. GIBBS ON THE FLORA AND PLANT FORMATIONS 
Professor Radlkofer, who kindly determined the above specimens, writes 
as follows :—“ If one distinguishes, as I did ‘many years ago (Sitzb. Math.- 
Phys. Acad. Muench. ix. (1879) 552), Arytera rufescens, Radlk. (Zygolepis 
rufescens, Turez. 1848, Ratonia rufescens, Turez. 1863), A. littoralis, BI., and 
A. angustifolia, Radlk., n. 4332 of your plants may be considered as belonging 
to the first, n. 2664 to the second, n. 2697 to the third. 
« But in the meantime I have got so many intermediate modifications, that 
I am now inclined to consider not only A. angustifolia as a mere form of 
A. littoralis, but also A. rufescens, distinguished only by a more compact 
inflorescence and rather reddish (than yellowish) ferruginous flower parts. 
* The exact names would then be :— 
4339. Arytera littoralis, Bl., forma rufescens, Radlk. in Sitzb. Math.-Phys. Acad. Muench. ix. 
(1879) 555.—Syn. A. rufescens, Radlk. 
2664. ^ " forma genuina, Radlk, ibid. 
2697. " " forma angustifolia, Radlk. ibid.—Syn. A. angustifolia, Radlk. 
l. c. 502. 
“There is also a var. major, King, which will become a ‘forma major, 
Radlk.’ and to which may be adjoined a ‘forma minor, Radlk., repre- 
sented by some specimens from Cochinchina and so on." 
OropHora FRUTICOSA, Blume, Rumphia, iii. 142. 
About Tenom and Kaningau, general as undershrub in the sec. forest. FI. 
Jan. 2625. 
Distrib. Borneo (B. N. B. Kudat, Fraser ; Kudat, Banguey, Tandjong 
Batu, Creagh). Java, Moluccas, and Philippines. 
OroPHoRA IMBRICATA, Blume, Rumphia, iii. 144. 
Tenom, 700—1000', general in the sec. forest. Fl. Fr. (young), Jan. 2863. 
Distrib. Borneo (Labuan, Motley ; Sarawak ; D. Borneo). 
A most characteristic shrub, +4 m. high, Aralza-like in habit, consisting 
of several simple stems with huge leaves about a metre long, aggregated at 
the apices, and a terminal inflorescence as long as the leuves. The perianth 
of the flowers is red and the fruit yellow in colour when collected. Motley 
notes on a specimen (808, Herb. Kew.) that “ the wood is exceedingly hard 
and is preferred above all others to make hooks for catching alligators’; he 
gives the native name as “ Kayu Mata Hari." 
HARPULLIA ARBOREA, Radlk, in Sitzb. Math.-Phys. Acad. Muench, xvi. 
(1886) 404. 
Kaningau plain, 1000’, near Station, in sec. jungle on banks of stream. 
d. Feb. 2955. 
Distrib. Philippines. 
This plant was kindly determined for me by Mr. Wright, as closely allied 
to H. arborea, Blume. On dissection of a flower (52081, Loher, Herb. Kew.)
