Sindora stipitata (Detarioideae, Leguminosae), a new species from Thailand

Sindora stipitata, a new species in the subfamily Detarioideae (Leguminosae), collected from Nakhon Phanom Province, Thailand, is described and illustrated. The new species is morphologically similar to S. leiocarpa but differs in its smaller stature (3–5 m high), 6-foliolate paripinnate leaves, falcate persistent stipules, presence of a petal auricle, absence of a petal claw, stipitate ovary and capitate stigma. A key to the Thailand and Malesia species of Sindora is provided

Effects of dietary supplementation of spray dried hog plum (Spondias pinnata (L.f.) Kurz) fruit powder on growth, digestive enzyme activity, and skin mucus immune parameters of climbing perch (Anabas testudineus (Bloch, 1972)

The effects of dietary supplementation of spray-dried hog plum (Spondias pinnata (L.f.) Kurz) fruit powder (SPP) on growth, digestive enzyme activity, and skin mucus immune parameters of climbing perch (Anabas testudineus (Bloch, 1972)) were examined. The fish (N = 330; 2.00±0.1 g) were assigned to five groups in triplicates. They were fed different SPP levels at 0, 5, 10, 15, and 20 g/kg diet for eight weeks. Flavonoids, terpenoids, phenolic compounds, tannins, steroids, glycosides, and glycosides were detected in SPP. The SPP containing diet significantly improved growth parameters (P 0.05). Intestinosomatic and hepatosomatic indices significantly declined in the fish fed SPP added diets (P < 0.05). There were significant elevations in digestive enzyme activities, amylase, protease, lipase, trypsin, pepsin, and esterase, in the tested fish compared to the control fish (P < 0.05). Additionally, fish fed SPP containing diets showed a significant enhancement of total protein, immunoglobulin M, lysozyme, antiprotease, alkaline phosphatase, and esterase in the skin mucus compared to the control group (P < 0.05). Significantly higher levels of superoxide dismutase, catalase, and total antioxidant capacity were detected in fish fed SPP containing diets compared to the control (P < 0.05). These findings suggest that dietary SPP supplementation can effectively enhance fish growth, digestive enzyme activities, and mucosal immune parameters in the climbing perch. The suitable level of SPP observed in this present study was 13.00 – 15.88 g/kg diet

A new species of Amorphophallus (Araceae) from northeastern Thailand

Amorphophallus sakonnakhonensis Chatan &amp;amp; Promprom, a new species from northeastern Thailand, is described and illustrated. The new species is most similar to A. harmandii Engl. &amp;amp; Gehrm. and A. linearis Gagnep., but it is distinguished by the combination of characters as follows: clear differences with A. harmandii are shorter style; disc-like, slightly smooth surface, concave centre, ca. 0.2 × 0.1 mm stigma; slightly cylindrical, slightly narrower upper part of staminate flower zone; slightly cylindrical to elongate-fusiform, erect or slightly erect, creamy white appendix. The clearly distinct morphology with A. linearis are disc-like, slightly smooth surface, concave centre, ca. 0.2 × 0.1 mm stigma; elliptic or obovate leaflet; 1–3 cm long, creamy white appendix. The preliminary conservation status was assessed, and the distinct characteristics of similar species were discussed

A new species of Dischidia (Apocynaceae, Asclepiadoideae) from North-eastern Thailand

Dischidia phuphanensis Chatan & Promprom, a new species from north-eastern Thailand, is described and illustrated. The new species is similar to D. tonkinensis Costantin, but is distinguished by the shape of its leaves, the apices of the staminal corona lobes, the colour of the corolla and the absence of a corolline corona. The distinguishing characters of similar species are discussed. A key for the identification of those species in Thailand without pitcher-like leaves is provided

A new species of Bauhinia L. (Caesalpinioideae, Leguminosae) from Nakhon Phanom Province, Thailand

A new liana species of the subfamily Caesalpinioideae (Leguminosae), namely Bauhinia nakhonphanomensis, collected from the Phulangkha National Park, Nakhon Pranom Province, Thailand, is described and illustrated. It is easily recognized by the following combination of characters: tendrilled liana, entire leaves, acuminate or caudate leaf apices, oblong or elliptic floral bud, floral bud 25–35 mm long, raceme or panicle inflorescence, 10–13 mm long hypanthium, anther opening by longitudinal slits. Important comparative morphological characters with some closely related species are discussed
