19,3 Merrill: Burman’s Flora Indica 335 
is the oldest one for this well-known species, which is very com- 
mon and widely distributed in the Philippines. 
CHEILANTHES Swartz 
CHEILANTHES TEN Ul FOLIA (Burm. f.) Sw. Syn. (1806) 129, 332. 
Trichomanes tenuifolia Burm. f. FI. Ind. (1768) 237. 
The type is an actual specimen from Pry on, probably of Javan 
origin. Dryopteris campestris Rumph. Herb. Amb. 6 : 77, t. 3 A, 
f. 2, is cited by Burman as representing his var. (3. The 
Rumphian figure is an excellent illustration of the common and 
widely distributed Cheilanthes tenuifolia Sw. 
PTERIS Linnaeus 
PTERIS ENSIFORMIS Burm. f. FI. Ind. (1768) 230. “Habitat in Zeylona 
& Java.” 
This is a common and well-known species of wide distribution 
in the Indo-Malayan region, extending to China, Polynesia, and 
Australia. 
PTERIS VITTATA Linn. Sp. Pi. (1763) 1074. 
Polypodium trapezoides Burm. f. FI. Ind. (1768) 233, t. 66, f. 2. 
“Habitat in Java.” 
Burman’s figure clearly represents a juvenile form of the very 
common Indo-Malayan species currently known as Pteris longi- 
folia Linn. Hieronymus considers that the Old World Pteris 
vittata Linn, is specifically distinct from the tropical American 
Pteris longifolia Linn. 
POLYPOD I UM Linnaeus 
POLYPODIUM SCOLOPENDRIUM Burm. f. FI. Ind. (1768) 232 ( scolo - 
pendria) . “Habitat in India.” 
Polypodium phymatodes Linn. Mant. 2 (1771) 306. 
The actual type of the species is doubtless Pryon’s Javan 
specimen for which the local name daun sembang is cited. Pre- 
Linnean references are given to Burman Thes. Zeyl. 196, t. 86, 
Breynius Cent. 190, t. 98, f. 1-3, Morison Hist. 3, /. 1A, t. 1, f. 
17, Plukenet Mant. 82, Almath. 94, and Phyt. 404, f. 1, 5. Bur- 
man’s specific name will replace the Linnean one for this very 
common and widely distributed species. Linnaeus in his de- 
scription of Polypodium phymatodes gives the same References 
as does Burman f. to Burman and to Plukenet. It is probable 
that his actual type was material transmitted to him by Burman.
