A PRELIMINARY REVISION Off PHILIPPINE MYKTAChVE. 335 



Genus best developed in Australia and New Caledonia, but extending through 

 the Malay Archipelago to the Malay Peninsula and Burma. 



The flowers are white or yellow; the degree of pubescence of the inflorescence 

 is variable. 



5. EUCALYPTUS L'Herit. 



Eucalyptus naudiniana P. Muell. Australas. Jour. Pharni. 1 (1886) 230; 

 Maiden in Proc. U. S. Nat. Mus. 26 (1903) 691, 692. 



Eucalyptus multiflora Rich ex A. Gray Bot. U. S. Expl. Exped. (1854) 554; 

 non Poir. Suppl. 2 (1811) 594; Merr. in Philip. Jour. Sci. 3 (1908) 83, pi. 2. 



Mindanao, District of Zamboanga, Caldera, U. B. Expl. Exped. (Wilkes) s. n. 



It has not as yet been possible to obtain additional Philippine material of 

 this species, although it is believed to be still abundant near the locality where 

 the Wilkes Expedition made its collections. 



New Britain. 



Eucalyptus tereticornis Sm. Bot. New Holl. (1793) 41. 



Luzon, Manila, Philip. Normal School 829, 830 Aurclia Malvar. Cultivated on 

 the grounds of the Normal School. Both specimens were collected on the same 

 day, from the same clump of trees, probably but not certainly from the same 

 tree. Mr. J. II. Maiden, Director of the Botanic Gardens, Sydney, N. S. W., has 

 very kindly confirmed the identifications, positively for no. 329 (flowering), and 

 probably for no. 330 (fruiting). It is also grown elsewhere in Manila. 



G. LEPTOSPERMUM Forst. 



Leptospermum flavescens Smith in Trans. Linn. Soc. 3 (1797) 2(52.

Even within our geographical limits, this is a most variable species, especially 

 as concerns the numbers from Malindang and Pulog, which have wider leaves 

 attaining 8.5 mm, definitely 3-nerved. Taken in its whole range, Tasmania to 

 Malacca, the range of variation has been even more widely interpreted, and I find 

 no sufficient warrant for segregating any of the Philippine material. It is uncer- 

 tain what may be finally agreed upon as the specific name, as L. porophyllum Cav. 

 Ic. 4 (1797) 17, pi. 330, f. 2, and L. thea Willd. Sp. PI. 2 (1799) 949, based 

 upon Melaleuca thea Wendl. Sert. Hannov. (1795-1798) 24. pi. 13. are both 

 considered to be cospecific with L. flavescens. 



As a mountain top tree or shrub this is not likely to receive local names, 

 the only one recorded, by Borden, from Mariveles, being Malasulasi. No economic 

 uses are noted, doubtless on account of its habitat. 



The generic distribution range hardly exceeds that of this species, being from 

 New Zealand to Burma.
