  • What Are Carnivorous Plants?
    What are carnivorous plants? The famous historical naturalist, Charles Darwin described carnivorous plants as “The most wonderful plants in the world”. The Swedish botanist Carl Linnaeus is quoted on carnivorous plants, “to think that plants ate insects would go against the order of nature as willed by God”. Against God’s will or not, we now know that Carnivorous plants are plants that eat small insects and animals. They thrive in wet, humid and nutrient poor environments. They trap and digest small invertebrates as a source of nitrogen to com- pensate the lack of nutrients in their habitat. Scientists believe that the carnivory gave them the evolution- ary advantage to grow in such nutrient poor environments where most other plants cannot survive. Most of you may naturally think that carnivorous plants are from warm tropical rain forests. However, they grow all over the world except antarctica. In fact, we do have 3 genera and 14 species of carnivorous plants in Rhode Island! They can be found in bogs, ponds and wetlands all around RI. Sarracenia The genus is also known as American pitcher plants. As the name suggests, they grow in North America and Canada. They employ pitcher shaped pitfall traps to capture their prey. The underside of the lid as well as the lips of the traps produce nectars that attract many insects such as fl ies and wasps. The prey falls into the trap because these parts of the plants are slippery. The prey won’t be able to get out of the trap easily, because the hairs inside the trap grow downWArds, and they will eventually be digested.

  • Investment in Carnivory in Utricularia Stygia and U. Intermedia with Dimorphic Shoots

(2007): Investment in carnivory in Utricularia stygia and U. intermedia with dimorphic shoots. – Preslia 79: 127–139. Utricularia stygia Thor and U. intermedia Hayne are aquatic carnivorous plants with distinctly di- morphic shoots. Investment in carnivory and the morphometric characteristics of both types of shoots of these plants were determined in dense stands growing in shallow dystrophic waters in the Třeboň basin, Czech Republic, and their possible ecological regulation and interspecific differences considered. Vertical profiles of chemical and physical microhabitat factors were measured in these stands in order to differentiate key microhabitat factors associated with photosynthetic and carnivo- rous shoots. Total dry biomass of both species in dense stands ranged between 2.4–97.0 g·m–2. The percentage of carnivorous shoots in the total biomass, which was used as a measure of the invest- ment in carnivory, ranged from 40–59% and that of traps from 18–29% in both species. The high percentage of total biomass made up of carnivorous shoots in both species indicates both a high structural investment in carnivory and high maintenance costs. As the mean length of the main car- nivorous shoots and trap number per plant in carnivorous shoots in both species differed highly sig- nificantly between sites, it is probable that the investment in carnivory is determined by ecological factors with low water level one of the potentially most important.

No part of this publication may be reproduced, stored in a retrieval system or database, or transmitted in any form or by any means, including photocopying, without written permission of the authors. Produced with financial assistance from The Couchiching Conservancy. The City of Kawartha Lakes Flora Project is sponsored by the Kawartha Field Naturalists based in Fenelon Falls, Ontario. In 2008, information about plants in CKL was scattered and scarce. At the urging of Michael Oldham, Biologist at the Natural Heritage Information Centre at the Ontario Ministry of Natural Resources and Forestry, Dale Leadbeater and Anne Barbour formed a committee with goals to: • Generate a list of species found in CKL and their distribution, vouchered by specimens to be housed at the Royal Ontario Museum in Toronto, making them available for future study by the scientific community; • Improve understanding of natural heritage systems in the CKL; • Provide insight into changes in the local plant communities as a result of pressures from introduced species, climate change and population growth; and, • Publish the findings of the project . Over eight years, more than 200 volunteers and landowners collected almost 2000 voucher specimens, with the permission of landowners. Over 10,000 observations and literature records have been databased. The project has documented 150 new species of which 60 are introduced, 90 are native and one species that had never been reported in Ontario to date.

Introduction Utricularia ochroleuca R. Hartm. is an amphibious/aquatic carnivorous plant occurring rel- atively rarely throughout Europe and North America in peat bogs and shallow standing dystroph- ic waters (Taylor 1989; Schlosser 2003). This species rarely flowers, is sterile, and is possibly of hybridogenic origin (i.e. U. minor × U. intermedia; Thor 1988). Thor (1988) split this taxon into two species, U. ochroleuca s. str. and U. stygia Thor (see Figure 1), on the basis of minor differ- ences in corolla morphology, the number of leaf teeth tipped with bristles, and, especially, in the structural details of the quadrifid (i.e. four-armed) ×-shaped glands (hairs) in their carnivorous traps. The rarity of flowering, the unreliability of the tooth number on the leaves as a determina- tion marker, preventing from easy determination (the numbers greatly overlap; Thor 1988; Schlosser 2003), and the rarity of these two species in Central Europe contributed partly to the neglect or refusal of the Thor’s concept of U. stygia as a separate species (in the Czech Republic e.g., Holub & Procházka 2000; Adamec & Lev 2002; Sirová et al.

(2014). It makes major strides in understanding the rare and under-collected aquatic vascular plants of YNP, the first work to be printed from among the researchers’ breadth of objectives in floristics, genetics and ecology. The authors, Barre Hellquist, Eric Hellquist and Jennifer Whipple, combined Flora of North America expertise with Park flora expertise in daunting fieldwork, herbarium work and lab work. The father- son pair of aquatic experts teamed with Whipple, long- time Park Botanist, to report three species new to the Wyoming flora, including Spiny-spore quillwort (Isoetes echinospora), Nodding water nymph (Najas flexilis) and Yellowishwhite bladderwort (Utricularia ochroleuca; see Additions to the Flora – p. 7), plus five species new to Montana or to YNP.

Correspondence: [email protected] Issued 01 December 2008 Abstract Karungalakudi is blessed with rich herbaceous flora including two carnivorous plant groups, viz. fly traps and bladder worts. In the present communication, a total of 6 insectivorous plants are reported, and it is confirmed that the reported occurrence of Drosera brevifolia Pursh, Utricularia minor L., U. resupinata Greene ex Bigelow and U. uniflora R. Br. in Karungalakudi is due to a misidentification. Key words: Karungalakudi, Fly-traps, Bladder worts, Misidentification. Introduction Karungalakudi is situated 40km away from Madurai district and it lies at 100 9’ 34” to 100 9’ 45”N latitude and 780 21’ 31” to 780 22’ 3”E longitude. Detailed botanical studies were conducted in various places of Karungalakudi between January 2006 – October 2008. All the collected specimens were poisoned, processed and labeled by standard herbarium methods (Jain and Rao, 1993). The correct identity of the herbarium specimens were then confirmed by further critical study with the help of relevant floras, monographs and revisions (Gamble and Fischer, 1997; Janarthanam and Henry, 1992; Matthew, 1983; Taylor, 1989). Their identification was later confirmed by matching specimens with previously authenticated specimens available at Botanical Survey of India (BSI), Southern Circle, Coimbatore.

Hartm., U. stygia Thor and U. bremii Heer ex Kölliker Aquatic carnivorous plants (Lentibulariaceae, Lamiales) are the four rarest and critically endangered European Utricularia (bladderwort) European distribution species from the generic section Utricularia. They are aquatic, submerged or amphibious carnivorous plants with Critically endangered species suction traps which grow in very shallow, standing dystrophic (humic) waters such as pools in peat bogs and fens Ecophysiological traits (also pools after peat or fen extraction), shores of peaty lakes and fishponds; U. bremii also grows in pools in old Ecological requirements shallow sand-pits. These Utricularia species with boreal circumpolar distribution (except for U. bremii) are still Overwintering Conservation commonly growing in northern parts of Europe (Scandinavia, Karelia) but their recent distribution in Central Europe is scarce to very rare following a marked population decline over the last 120 years. All species have very thin linear shoots with short narrow to filamentous leaves bearing carnivorous traps (bladders, utricles) 1−5 mm large. The first three species form distinctly dimorphic shoots differentiated into pale carnivorous ones bearing most or all traps, and green photosynthetic shoots with only a few (or without) traps, while the last species usually forms non-differentiated (monomorphic) or slightly differentiated shoots.
