Lindsaya Nitens, Blume.—The simple form L. Recurvata is rare in Ceylon. It is found in the 
southern province. 
Lindsay a Lanceolata, Lab.—The simple fronded form L. Griffithiana occurs in the southern 
province, growing along with the typical form. At Etangwella, in Matale, this fern 
approaches L. Heterophylla, the pinnae being very distinctly again pinnate, but the pinnules 
are rounded, and have no main vein. In this respect they differ from the typical form of 
L. Heterophylla, and are probably distinct. 
Lindsaya Heterophylla, Dry.—The true typical form of this species, as distinguished from the 
abnormal form of L. Lanceolata, above mentioned, is rare. The venation is distinctly 
anastomosing; therefore the fern is a true Schizoloma, in which our species differs from 
that figured by Beddome. 
Adiantum Catjdatum, L., varies considerably from the densely villous, typical form, to the 
almost glabrous form of A. Rhizophorum; and from the almost entire form of pinna of 
A. Edgworthii, Hk., to the Matale type, in which the pinna is cut down nearly to the 
rachis. Specimens of all intermediate forms exist at Kew, and they are therefore united 
under one species in the Synopsis. 
Cheilanthes Mysurensis, Wall., attains a most luxurious growth on the road from Battotta to 
Oodelamana, with fronds 18 inches in height. 
Cheilanthes Thwaitesii, Kuhn.—Dr. Kuhn, ‘Linntea,’ vol. xxxvi., p. 82, is of opinion that our 
Ceylon species, hitherto referred to C. Varians, Hk., is, in fact, distinct; and, as Mr. Baker 
agrees in this opinion, the new name is adopted in my list on their authority. My own 
specimens of the typical Himalayan plant do not enable me to discover any specific 
difference between the two. The Ceylon plant is said to have a tendency to he white 
farinose underneath. 
Pteris Hookeriana, Agardh., regarded by Dr. Thwaites as a variety of P. Cretica, is distin¬ 
guished by its having a distinct involucre independent of the edge of the frond. The 
involucre of P. Cretica is the revolute margin of the frond. This character is constant in 
the specimens at Kew, and in very numerous other specimens to which reference has been 
made. The species seems otherwise distinct, and is so regarded in the Sjmopsis. 
Pteris Quadriaurita, Betz, is extremely variable. In its simplest form it resembles P. Crenata 
in having its pinnae quite entire. Between this and the typical form of the plant, there 
exists in Ceylon every possible intermediate form. Perfectly simple and partly compound 
forms have been found growing from the same caudex. The greatest variety may be found 
in the Matale and Kurunagalla districts. One of these abnormal forms is figured by 
Beddome, who regarded it as a new species, and called it P. Otaria. Some specimens 
very closely resemble P. Semipinnata, from which species, however, all the forms of 
P. Quadriaurita are distinct. A specimen sent to Kew from Peradeniya by Gardner, under 
the name of P. Semipinnata, is clearly one of these abnormal forms of Quadriaurita. This 
specimen being the only authority for attributing the species to Ceylon, it is omitted in 
this catalogue.
