BLECH NUM Linnaeus 
BLECHNUM INDICUM Burm. f. FI. Ind. (1768) 231. “Habitat in Java.” 
This is almost certainly identical with Blechnum serrulatum 
Rich. Act. Soc. Hist. Nat. Paris 1 (1792) 114, and if this proves 
to be the case Burman’s name should be adopted for this pan- 
tropic species. It is the only Malayan species of the genus to 
which Burman’s description applies. 
BLECHNUM ORIENTALE Linn. Sp. PI. (1753) 1077. 
Polypodium simplex Burm. f. FI. Ind. (1768) 235. “Habitat in Ara- 
boina.” 
Burman apparently had a Javan specimen collected by Klein- 
hof. Lonchitis amboinica rubra Rumph. Herb. Amb. 6; 70, t. 
30, f. 1, cited as a synonym, is clearly identical with the common 
and widely distributed Blechnum orientale Linn. 
STENOCHLAENA J. Smith 
STENOCHLAENA PALUSTRIS (Burm. f.) Bedd. Ferns Brit. Ind. Suppl. 
(1876) 234. 
Polypodium palustre Burm. f. FI. Ind. (1768) 234. “Habitat in indiis.” 
Burman apparently had a Javan specimen, as he cites the 
local Javanese name as daun peekou, although his description is a 
compiled one from pre-Linnean authors. The species is perhaps 
typified by the reference to Linn. FI. Zeyl. 200 and to Burm. 
Thes. Zeyl. 100, t. 46. The species is a well-known one of wide 
distribution in the Indo-Malayan region. 
HEMIONITiS Linnaeus 
HEM ION ITIS ARI FOLIA (Burm. f.) Moore Index (1859) 114. 
Aspleniuvi arifolium Burm. f. FI. Ind. (1768) 231. “Habitat in India.” 
A well-known characteristic species of wide distribution in the 
Indo-Malayan region. 
ADIANTUM Linnaeus 
ADIANTUM PHILIPPENSE Linn. Sp. PI. (1753) 1094. 
Adiantum ( Adianthum ) lunulatum Burm. f. FI. Ind. (1768) 235. 
“Habitat in Malabara & Java.” 
The actual type was apparently a Javan specimen, the Malabar 
reference being apparently added either from Avenka Rheede 
Hort. Malabar. 12: 72, t. 40, or from Petiver Gaz. t. 54, f. 10, 
both cited as representing the species. The Linnean binomial
