Abstract:
Morphological variation in northern Australian Drosera indica L. specimens, mainly from northwestern Australia, was studied by cluster analysis and ordination (MDS). Sixty-two accessions were scored for 26 morphological characters representing five vegetative, nine floral and 12 seed features. The accessions were differentiated into three distinct morphotypes mainly on the basis of seed and stamen characters. These morphotypes occurred sympatrically at a number of localities over a wide area across northern Australia, but without obvious evidence of intergradation. This suggests that these morphotypes represent cryptic species within the D. indica complex.

Abstract:
The Japanese sundews that have previously been collectively called D. indica L. (especially after the influential Flora of Japan, Ohwi 1965:492) are being split up. Various authors (e.g., Watanabe 2013) are trying to re-establish or create one or two additional species assumed endemic to Japan, following the contemporary trend to recognize a number of segregate taxa in Drosera sect. Arachnopus (Greek for “spider leg”), the group that contains D. indica. Previous research (Schlauer et al. 2017, 2018, 2019) has demonstrated a rather unexpected diversity in the naphthoquinones that are characteristic for the different species now recognized in this group. While a few Australian species contain ramentaceone (7-methyljuglone), most contain the regio-isomer plumbagin (2-methyljuglone). So far, only D. indica s.str. (accessions from Asia and Africa have been investigated) contains both isomers in the same plant. The morphological diversity found in Japan thus prompted a chemical investigation, the results of which are reported here.

Abstract:
Low altitude granitic hillock systems prevalent in Palghat (Palakkad) Gap region of southern Western Ghats were analyzed for seasonal dynamics in wetland taxa associated with marshy ephemeral flush vegetation, small ephemeral pools and deep rock pools. Due to characteristic habitat features, such systems harbor a unique pattern of microhabitats and associated floristic components. Wet phase in rocky outcrops in the monsoon season establishes a hydro-geomorphic habitat that supports establishment of wetland taxa like Eriocaulon, Drosera, Utricularia, Dopatrium, and Rotala. Seasonal shift in the floral associations was evident in tune with wetland dynamics. Wet rocks support ephemeral flush vegetation which display some unique plant associations of species of Eriocaulon, Utricularia, Drosera, Cyanotis, Murdannia, and Lindernia. Small ephemeral pools displayed taxa like Rotala malampuzhensis R.V. Nair, Dopatrium junceum (Roxb.) Buch.-Ham. ex Benth., D. nudicaule (Willd.) Benth., Monochoria vaginalis (Burm.f.) C. Presl, and Cyperus iria L. Rocky pools are the habitats of aquatic angiosperms like Nymphaea nouchali Burm. f., Ludwigia adscendens (L.) H. Hara, Utricularia aurea Lour. and Hydrilla verticillata (L.f.) Royle. The study documented 121 plant taxa from 37 families during a wet phase from rocky outcrops of the study area. Gradual shift in vegetation is evident as water recedes from granitic hillocks. During the period from December to March, the rocky pools dry up which results in a shift in the vegetation pattern where Poaceae members form the dominant elements. As most of the rocky outcrops are exposed to extreme temperature and acute water shortage, the taxa inhabiting such ecosystems tend to evolve much faster than in other habitats. Moreover, the vicinity of these hillocks in the Palghat Gap region to human settlements, face threats like fire, grazing, quarrying, dumping of wastes etc. which may cause considerable loss to the very sensitive plant communities which are not yet fully documented.

Abstract:
Carnivorous plants with unique mode of nutrition and physiology have attracted the attention of the microbiologists in studying the microbial diversity inherent in their internal environment. This work is aimed to study the culturable endophytic diversity of the carnivorous plants Drosera burmannii Vahl., Utricularia stellaris L. f. and U. exoleta R. Br. collected from different districts of West Bengal, India. During the study, a total of 168 phenotypically distinct endophytic bacteria were isolated and their colonization frequency, isolation rate, Shanon-Weaver, Gleason and Simpson diversity indices were analyzed. The metabolic activities of these endophytic isolates have been evaluated following standard microbiological methods. A preliminary screening have led to the selection of nineteen bacterial isolates having potent antimicrobial, antioxidant, proteolytic and plant growth promoting activities involving IAA and siderophore production as well as phosphate solubilization. Detailed phenotypic characterization followed by the determination of simple matching coefficient has tentatively assigned these potent endophytic bacterial isolates to the genera Bacillus, Acetobacterium, Pseudomonas, Klebsiella, Alcaligens and Xanthomonas. The metabolic attributes of these bacterial endophytes leading to the production of bioactive compounds therefore deserve special attention in understanding the survival and growth strategies of the carnivorous hosts in nutrient deficient environment as well as exploring their biosynthetic products in human health and hygiene.
