<strong>Enumeration</strong> <strong>of</strong> <strong>Thai</strong> pteridophytes collected<br />
<strong>during</strong> <strong>1965</strong>-<strong>66</strong><br />
by<br />
Matazi TAGAWA and Kunia IWATSUKI<br />
From November <strong>1965</strong> to February 19<strong>66</strong>, the Center for Southeast Asian Studies<br />
sent a botanical party to <strong>Thai</strong>land and the first <strong>Thai</strong>-Japanese Botanical Expedition<br />
was begun in cooperation with the Royal Forest Department in Bangkok. During<br />
a sojourn <strong>of</strong> more than one hundred days, we observed and collected a comprehensive<br />
number <strong>of</strong> fern species as well as flowering plants and mosses. Here is given an<br />
enumeration <strong>of</strong> all pteridophytes collected on this trip. In this paper, however,<br />
only a list <strong>of</strong> the specific identifications <strong>of</strong> the collections has been made. In the<br />
course <strong>of</strong> the investigation <strong>of</strong> the fern flora <strong>of</strong> <strong>Thai</strong>land, we met with a good many<br />
facts new to science. This information will be forthcoming in other publications.<br />
The field work <strong>of</strong> the Expedition was accomplished by the following four<br />
Japanese botanists and a <strong>Thai</strong> entomologist, who accompanied the Japanese group<br />
from beginning to end:<br />
Motozi T AGAWA, the leader, on pteridophytes and general botany<br />
Kunio IWATSUKI, on pteridophytes<br />
Na<strong>of</strong>umi KITAGAWA, on bryophytes<br />
Nobuyuki FUKUOKA, on flowering plants in general<br />
Dumrong CHAIGLOM, on entomology in relation to forestry.<br />
The itinerary <strong>of</strong> the Expedition was as follows (with the vascular plant col-<br />
lectors' names following the location) :<br />

The approximate locations <strong>of</strong> the places cited above are shown on the map.<br />
(Fig. 1). In the specimen citations following, no collectors' names will be given<br />
and specimens will be indicated only by their T -numbers, which are the field numbers<br />
<strong>of</strong> the specimens collected by the <strong>Thai</strong>-Japanese Botanical Expedition.<br />
About 300 species <strong>of</strong> pteridophytes have been recorded so far in <strong>Thai</strong>land. In<br />
our enumeration, 116 genera and 442 species are listed. In order to keep our report<br />
as short as possible, the references cited have been restricted to only those necessary<br />
to understand the fern flora <strong>of</strong> <strong>Thai</strong>land. Frequently cited literature will be referred<br />
to in abbreviated forms: e.g.<br />

vol. II. Singapore.<br />

Within the range <strong>of</strong> one genus, the revisions will be cited in shortened forms,<br />
as in the case <strong>of</strong> the florae and the lists, by authors' names and the year <strong>of</strong><br />
publication.<br />
In our enumeration, the genera and species are arranged mainly in accordance<br />
with the system <strong>of</strong> Holttum (1954), though the names and circumscription <strong>of</strong> some<br />
genera have been changed in the light <strong>of</strong> recent literature. This does not necessarily<br />
mean that we consider Holttum's system as the best ever proposed. In our<br />
opinion, the florae should be published with the aim <strong>of</strong> usefulness, especially for<br />
those concerned. In the case <strong>of</strong> <strong>Thai</strong> ferns, their close relationship to well-known<br />
Malayan ferns cannot be denied; therefore, we have used Holttum's system for<br />
24 - 24-
authorities. Especially, the botanical team received various aid and assistance from<br />
the National Research Council and the Royal Forest Department. Mr. Tern Smitinand,<br />
the curator <strong>of</strong> the Forest Herbarium <strong>of</strong> the Royal Forest Department, kindly<br />
suggested interesting localities and made ideal arrangements for which we are very<br />
grateful. Mr. Dumrong Chaiglom accompanied the group from beginning to end<br />
and we appreciate his invaluable aid. Without their hearty and consistent support,<br />
our expedition would not have been as fruitful as it was. Pr<strong>of</strong>. T. Motooka and<br />
Mr. S. Iijima <strong>of</strong> the Center for Southeast Asian Studies <strong>of</strong> Kyoto University aided<br />
the botanical team greatly by arranging for the field work in <strong>Thai</strong>land. Pr<strong>of</strong>essors<br />
S. Iwamura, J. Ashida, T. Shidei and R. Yoshii, all <strong>of</strong> Kyoto University, generously<br />
supported our botanical trip. Pr<strong>of</strong>essor S. Kitamura and the staff members <strong>of</strong> the<br />
laboratory <strong>of</strong> plant taxonomy at Kyoto University rendered all kinds <strong>of</strong> assistance.<br />
We would like very much to express our most sincere thanks to all who helped<br />
to make our trip a success.<br />

such characters as: the axes <strong>of</strong> fronds densely and persistently hairy, the teeth on<br />
segments larger, the internal cell walls <strong>of</strong> the laminar part thick and wavy, and<br />
the receptacles lengthened to some extent. We are not certain whether it is correct<br />
or not to refer our materials to such a variable species, but at present they may<br />
better be placed tentatively in H. barbatum.<br />

There remain some doubts to refer the above materials to the nominal species.<br />
With narrower segments and irregular false veinlets, our specimens accord well<br />
with the Philippine plants <strong>of</strong> C. brevipes which is known to be much variable in its<br />
size and accordingly in the construction <strong>of</strong> fronds. In the presence <strong>of</strong> the occasional<br />
submarginal false veinlets and in the form <strong>of</strong> sari, especially in not so long tube,<br />
our plants differ from C. megistostomum, from which, however, we can not distin<br />
guish C. brevipes sufficiently.<br />
