Apocynaceae-Apocynoideae)
THE NERIEAE (APOCYNACEAE-APOCYNOIDEAE) A. J. M. LEEUWENBERG1 ABSTRACT The genera of tribe Nerieae of Apocynaceae are surveyed here and the relationships of the tribe within the family are evaluated. Recent monographic work in the tribe enabled the author to update taxonomie approaches since Pichon (1950) made the last survey. Original observations on the pollen morphology ofth egener a by S.Nilsson ,Swedis h Natural History Museum, Stockholm, are appended to this paper. RÉSUMÉ L'auteur étudie lesgenre s de la tribu desNeriea e desApocynacée s et évalue lesrelation s del a tribu au sein de la famille. Un travail monographique récent sur la tribu a permit à l'auteur de mettre à jour lesapproche s taxonomiques depuis la dernière étude de Pichon (1950). Lesobservation s inédites par S. Nilsson du Muséum d'Histoire Naturelle Suédois à Stockholm sur la morphologie des pollens des genres sontjointe s à cet article. The Apocynaceae have long been divided into it to generic rank and in his arrangement includ two subfamilies, Plumerioideae and Apocynoi- ed Aganosma in the Echitinae. Further, because deae (Echitoideae). Pichon (1947) added a third, of its conspicuous resemblance to Beaumontia, the Cerberioideae, a segregate of Plumerioi it may well be that Amalocalyx (Echiteae— deae—a situation which I have provisionally ac Amalocalycinae, according to Pichon) ought to cepted. These subfamilies were in turn divided be moved to the Nerieae. into tribes and subtribes. Comparative studies Pichon's system is artificial, because he used have shown that the subdivision of the Plume the shape and the indumentum of the area where rioideae is much more natural than that of the the connectives cohere with the head of the pistil Apocynoideae. -

V ESSEL GROUPING PATTERNS IN SUBFAMILIES APOCYNOIDEAE AND PERIPLOCOIDEAE CONFIRM PHYLOGENETIC VALUE OF WOOD STRUCTURE WITHIN APOCYNACEAE 1 Frederic Lens, 2,7 Mary E.

Based on LM and SEM observations of 56 Apocynoideae species — representing all currently recognized tribes — and eight Periplocoideae, we found strik- ing differences in vessel grouping patterns (radial multiples vs. large clusters) between the mainly nonclimbing apocynoid tribes (Wrightieae, Malouetieae, Nerieae) and the climbing lineages (remaining Apocynoideae and Periplocoideae). The presence of large vessel clusters in combination with fi bers in the ground tissue characterizing the climbing Apocynoideae and Periplocoideae clearly contrasts with the climbing anatomy of the rauvolfi oids (solitary vessels plus tracheids in ground tissue), supporting the view that (1) the climbing habit has evolved more than once in Apocynaceae, (2) the three nonclimbing apocynoid tribes are basal compared to the climbing apocynoids, and (3) Periplocoideae belong to the crown clade. -

ENDRESS,3 AND BIRGITTA BREMER2 2 Department of Systematic Botany, Uppsala University, Villav. 6, S-752 36 Uppsala, Sweden; and 3 Institute of Systematic Botany, University of ZuÈrich, Zollikerstrasse 107, CH-8008 ZuÈrich, Switzerland The monophyly and classi®cation of the tribe Wrightieae of the subfamily Apocynoideae (Apocynaceae) are cladistically investigated. Nine taxa from the Wrightieae sensu Leeuwenberg, nine from other Apocynoideae sensu lato (s.l., including two from the traditional Asclepiadaceae), and two outgroup taxa from the Plumerioideae (Apocynaceae) were scored for rbcL sequence data and morphological data, mainly ¯oral characters, and analyzed using successive weighting parsimony analysis. The Wrightieae sensu Leeuwenberg are shown to be largely paraphyletic, the constituent taxa being dispersed among four monophyletic clades. Previously not suggested relationships indicated by the study are the association of Pachypodium with Funtumia, Holarrhena, and Mascarenhasia and the position of Beaumontia close to Trachelospermum. A reclassi®cation of the Wrightieae is discussed, in which three of the identi®ed clades are recognized as tribes, the Wrightieae sensu stricto (s.s.), the Nerieae, and the Malouetieae. The support for the Wrightieae s.s. is very strong, as evaluated with Bremer support and bootstrap analysis. The Malouetieae are also strongly supported, but the Nerieae less so. Using potential morphological synapomorphies identi®ed in the study, circumscription of the tribes is discussed. A potential pseudogene of rbcL is reported for Beaumontia.

The data were analyzed by using independent-samples t-test, one way ANOVA, cultural importance index (CI), informant consensus factor (ICF), and fidelity level (FL %). The results showed that there were 329 plant species from 89 families used in the daily life by the Phu Thai.The largest number of plant species were from Fabaceae (42 species, 12.77 %), followed by Zingiberaceae (20 species, 6.07 %), and Poaceae (15 species, 4.56 %). One hundred and ninety nine species were edible and used for consumption, 176 species for medicine, 56 species for cultural purposes, and 79 for other uses. The highest informant consensus factor (ICF) of medicinal plants were calculated for injuries (ICF = 0.961) indicating the highest degree of agreement among the informants knowledge of medicinal plants used to treat disorders in this category. -

Plant Diversity in Burapha University, Sa Kaeo Campus
doi:10.14457/MSU.res.2019.25 ICoFAB2019 Proceedings | 144 Plant Diversity in Burapha University, Sa Kaeo Campus Chakkrapong Rattamanee*, Sirichet Rattanachittawat and Paitoon Kaewhom Faculty of Agricultural Technology, Burapha University Sa Kaeo Campus, Sa Kaeo 27160, Thailand *Corresponding author’s e-mail: [email protected] Abstract: Plant diversity in Burapha University, Sa Kaeo campus was investigated from June 2016–June 2019. Field expedition and specimen collection was done and deposited at the herbarium of the Faculty of Agricultural Technology. 400 plant species from 271 genera 98 families were identified. Three species were pteridophytes, one species was gymnosperm, and 396 species were angiosperms. Flowering plants were categorized as Magnoliids 7 species in 7 genera 3 families, Monocots 106 species in 58 genera 22 families and Eudicots 283 species in 201 genera 69 families. Fabaceae has the greatest number of species among those flowering plant families. Keywords: Biodiversity, Conservation, Sa Kaeo, Species, Dipterocarp forest Introduction Deciduous dipterocarp forest or dried dipterocarp forest covered 80 percent of the forest area in northeastern Thailand spreads to central and eastern Thailand including Sa Kaeo province in which the elevation is lower than 1,000 meters above sea level, dry and shallow sandy soil. Plant species which are common in this kind of forest, are e.g. Buchanania lanzan, Dipterocarpus intricatus, D. tuberculatus, Shorea obtusa, S. siamensis, Terminalia alata, Gardenia saxatilis and Vietnamosasa pusilla [1]. More than 80 percent of the area of Burapha University, Sa Kaeo campus was still covered by the deciduous dipterocarp forest called ‘Khok Pa Pek’. This 2-square-kilometers forest locates at 13°44' N latitude and 102°17' E longitude in Watana Nakorn district, Sa Kaeo province.
