labeled “Luzon.” No representative of the genus has been found in the 
Philippines, and Lobb’s specimen was probably from Singapore or Borneo, 
where the species is common. 
VIOLACEAE 
Ionidium thymifolium Presl Rel. Haenk. 2 (1835) 97 “Habitat in insula 
Luzon.” No representative of the genus is known from the Philippines. 
Presl himself later (Bot. Bemerk. 11) credits I. thymifolium to the Cape of 
Good Hope. 
Viola philippica Cav. Ic. 6 (1801) 19, t. 529, f. 2. “Habitat in Insula 
Luzon tertio a Manila lapide, ibique Oxalis sensitiva; Morinda axillaris; 
Iusticia nasuta; Mogorium sambac; Scirpus dipsaceus, barbatus, miliaceus, 
et dichotomus.” This was certainly very definitely localized by Cavanilles, 
yet there is every reason to believe that Viola philippica was not from the 
Philippines, but probably from South America, Mexico, or California. The 
indigenous species of Viola in the Philippines are all from high altitudes, and 
none of them approach the species figured and described by Cavanilles; none 
occur within many miles of Manila except the cultivated Viola odorata L. 
RHIZOPHORACEAE 
Anisophyllea DISTICHA Hook.; Rolfe in Journ. Bot. 23 (1885) 212. This 
was admitted as Philippine on the basis of a Lobb specimen labeled “Luzon.” 
No representative of the genus is known from the Philippines, and A. 
disticha can safely be eliminated from the Philippine list. Lobb’s specimen 
was probably from Singapore or Borneo, where the species is common. 
MYRTACEAE 
Baeckea frutescens Linn.; F.-Vill. Novis. App. (1880) 82. “Philipp. 
(Cuming).” The genus has no representative in the Philippines. The 
Cuming specimen mentioned by F.-Villar is Cuming 2269, and is from 
Malacca. It is correctly localized by Schauer in his description of Baeckea 
cumingeana (sic!), which was based on this collection (Walp. Ann. 2: 920). 
Rhodamnia trinervia Blume; Duthie in Hook. f. FI. Brit. Ind 2 (1878) 
468. The Philippine record is based on a Cuming specimen from Malacca; 
no representative of the genus is known from the Philippines. 
EPACRIDACEAE 
Leucopogon malayanus Jack; Vidal Rev. PL Vase. Filip. (1886) 173. 
This was admitted as Philippine on the basis of a specimen collected by 
Lobb and labeled “Luzon,” with the qualifying statement by Vidal: “Como 
se ha indicado ya, las localidades de las plantas de Lobb no merecen entera 
confianza, asi toda especie con solo ejemplares de ese colector queda algo 
dudosa para nuestra flora.” The species can with safety be excluded from 
the Philippine flora, as it has not appeared in our comprehensive collections. 
Lobb’s specimens were probably from Borneo, Singapore, or Java. 
MELASTOMATACEAE 
Marumia zeylanica Blume; ,C. B. Clarke in Hook. f. FI. Brit. Ind. 2 
(1870) 542 credits this species to the Philippines, citing no specimen, but 
Cuming 2383 in the Kew Herbarium under a Philippine label, accounts for 
132966 3
