ABSTRACT

The study on Pteridophytes in West Timor was conducted in January to September 2001. The identification of collected specimen and cytological observation were perfomed in Herbarium Bogoriense Bogor. The objectives are to make an inventory to the pteridophytes species and their distribution on different ecosystem types.

Based on this study there are 58 species belonging to 36 genera. They are

Achrosticum (1 species), Adiantum (5 species), Amphineuron (3 species), Asplenium

(4 species), Athyrium (1 species), Belvisia (1 species), Botrycium (1 species),

Ceratopteris (1 species), Christella (4 species), Ctenitis (1 species), Ctenopteris (1 species), Cyathea (1 species), Davallia (2 species), Dennstaedtia (1 species),

Diplazium (2 species), Doryopteris (1 species), Drynaria (2 species), Dryopteris (1 species), Gleichenia (1 species), Heterogoniurn (1 species), Humata (1 species),

Lycopodium (1 species), Microlepia (1 species), Microsorium (1 species),

Nehprolepis (2 species), Oleandra (1 species), Platycerium (1 species), Pleocnemia

(1 species), Pteris (5 species), Pyrrosia (1 species), Sellaginela (1 species), Selliguea

(1 species), Sphaerostephanos (2 species), Tectaria (1 species), Trichomanes (1 species), and Vittaria (1 species).

There are various fiecquency distribution patterns of fern species in West Timor which are depended on their ecosystem. The savanna ecosystem has a lower number of species (12 species), and the mixed tropical monsoon forest ecosystem (26 species), and montane ecosystem (30 species) have higher number species of fern.

Cytological observation show that, at West Timor there are no different on chromosome number in different ecosystem types. Based on cytological study from eight species show that Adiantum cuneatum 2n = 60; Christella parasitica 2n = 140;

Drynaria sparsisora 2n = 74 in two ecosystem types (savanna and mixed tropical monsoon forest); and on the other hand chromosome number of Nephrolepis biserrata 2n = 82 and Pteris vittata 2n = 60 at the three ecosystem type.

Di Timor Barat terdapat pola variasi jenis yang beragam, pada setiap tipe ekosistem tempat diiana tumbuham paku hidup. Tipe ekosistem savana memiliki jumlah jenis yang paling sedikit (12 jenis), sedangkan tipe ekosistem hutan monsun tropis campuran merniliki jumlah jenis yang banyak (26 jenis), demikian pula pada tipe ekosistem pegunungan memiliki jumlah jenis yang paling tinggi (30 jenis).

Pengamatan sitologi menunjukkan bahwa di Timor Barat perbedaan tipe ekosistem tidak mempengaruhi jumlah kromosom. Jumlah kromosom Adiantum cuneatum 2n = 60; Christellaparasitica 2n = 140; Drynaria sparsisora 2n = 74, pada dua tipe ekosistem (savana dan hutan monsun tropis campuran), sedangkan jumlah kromosorn Neprolepis biserruta 2n = 82, dun Pteris vittata 2n = 116 pada tiga tipe ekosistern (savana, hutan mosun tropis campuran dan pegunungan).
