Abstract

Sarah Agustiorini & Nunik Sri Ariyanti. 2018. New records of Fissidens (Bryophyta: Fissidentaceae) for Borneo. Floribunda 6(1): 12–18. — Two species of the genus Fissidens, namely F. bogoriensis Fleisch. and F. braunii (C. Mull.) Dozy & Molk., are reported as new records for the bryoflora of Borneo. F. bogoriensis was previously reported only occured in Java, Malay Peninsula, New Guinea, Indo-Pacific Islands, China, and Japan. F. braunii was found in Sumatra, Malay Peninsula, New Guinea and Polynesia. In the current exploration these two species were found in the Eastern Borneo. Descriptions, notes, and ilustrations are provided.Keywords: Borneo, Fissidens, New Record. Sarah Agustiorini & Nunik Sri Ariyanti. 2018.

Abstract

Recent more intensive explorations and collections of hornworts in Mt. Slamet indicated that six species can be recognized, namely Anthoceros punctatus, Folioceros fuciformis, Phaeoceros carolinianus, P. exiguus, Dendroceros difficilis, and Megaceros flagellaris. Since originally only one species D. difficilis was recorded from this area, this means that five species represent new records for the area, whereas P. exiguus is not only a new record for Java, but it is also a new record for Malesia.

Abstract

Paku merupakan tumbuhan vaskular penghasil spora yang terdiri atas akar, rimpang dan ental.  Bagian rimpang, stipe dan bagian muda dari helaian daun seringkali ditutupi oleh indumentum (sisik/rambut). Penelitian ini bertujuan untuk mengkarakterisasi mikromorfologi dari 18 jenis paku terpilih yang dijumpai di kawasan kebun teh Kampung Citalahab. Pengambilan sampel dilakukan dengan metode jelajah bebas. Karakter mikromorfologi diamati dan didokumentasikan menggunakan mikroskop. Hasil pengamatan disajikan dalam bentuk gambar dan dianalisis secara deskriptif. Hasil karakterisasi mikromorfologi menunjukkan variasi pada warna sisik dan bentuk sisik. Karakter mikromorfologi yang diamati dapat memperkaya bukti taksonomi setiap jenis paku.

Abstract

Ibna Hayati, Alex Hartana, Nina Ratna Djuita & Nunik Sri Ariyanti. 2022. Morphological Variation of Kedondong  (Spondias dulcis Parkinson) in Central Part of  Sumatra. Floribunda 6(8): 315–323 — Kedondong (Spondias dulcis Parkinson), is widely cultivated in the tropics and reported possibly native plant from Malesia and Pacific. Since a long time several regions in Indonesia has been known as producing area. Around 60s, Sumatra has reputable kedondong from sabang which has sweet flavour and large size. However information on the morphological variation of kedondong germplasm is still limited. The objective of this study was to describe and grouped morphological variation of kedondong germplasm in central part of Sumatra. The specimens were explored and collected from Riau, West Sumatra, and Jambi. Fifty morphological characters were observed and scored for grouping analysis using UPGMA methods. Some characteristics of kedondong from central part of Sumatra are very varied. The kedondong specimens in the cluster analysis grouped into two main groups A and B based on the color of the mature fruit, but these characteristics may not qualify to be used as standard criteria for evaluating cultivated variety because within the group there are still variations in other characters, such as size and shape of the fruits. However based on fruit type, sweet kedondong tends to has oblong type.
