  • How to Identify New Brunswick Violets

    How to Identify New Brunswick Violets

    How to Identify New Brunswick Violets Sponsored by the New Brunswick Botany Club Introduction : Violets are always exciting to find while walking in the field in early summer. They are so easy to identify as to their genus. However, most people will stop there, because they are not easy to identify at the species level - many minute characteristics must be examined...and they easily form difficult to describe hybrids. Approached in the right mix of adventurousness and humility, sorting out violets can be fun. However, should efforts end in exasperation, just keep in mind that the violets never read the botany books. (Choukas-Bradley 2004). In order to correctly identify violets the following features must be examined : these are stems, leaves and flowers. Above-ground stems are : a) acaulescent (stemless) b) caulescent (stemmed) In acaulescent species the rhizomes or stolons gives rise to a crown of basal leaves and flowers. Care should be taken to assess the position of leaves since some species (i.e. Viola adunca and Viola labradorica - caulescent species) may have very short (less than 1 cm) stems at flowering and may appear acaulescent. Below-ground stems are : a) slender rhizome b) stout rhizome c) taproot Rhizomes are slender (mostly 1 to 3 mm thick) and travel horizontally underground, or stout (mostly 4 to 6 mm thick) and are usually oriented vertically underground - these are the perennials. Annuals have a vertical, fibrous root known as a taproot. To evaluate a slender versus a stout rhizome in the field, just place your thumb and index vertically around the base of a plant, near the soil.

This challenge is most serious in tribe Caryophylleae since the supposed genera seem to be highly artificial, and the available morphological evidence cannot effectively be used for delimitation and exact determination of taxa. The main goal of the present study was to re-assess the monophyly of the genera currently recognized in this tribe using molecular phylogenetic data. We used the sequences of nuclear ribosomal internal transcribed spacer (ITS) and the chloroplast gene rps16 for 135 and 94 accessions, respectively, representing all 16 genera currently recognized in the tribe Caryophylleae, with a rich sampling of Gypsophila as one of the most heterogeneous groups in the tribe.

    Yellow Archangel Lamium – a Devil to Control!

    ALIEN PLANT INVADERS: Yellow Archangel Lamium – A Devil To Control! A series of articles on how to identify and manage some common invasive species on Salt Spring Island, by Jean Wilkinson, Stewardship Committee, Salt Spring Island Conservancy (former articles available on SSIC Web-site) The spread of invasive species is a very serious threat to our native flora and ecosystems, but we can help reduce the impacts of invasive plants by not planting them and by preventing and controlling infestations in our yards and neighbourhoods. In our region one of the most common and challenging invasive plants is Yellow Archangel, aka Dead-nettle. A type of Lamium native to Europe, Asia, and North Africa, it is often used in hanging baskets or sold as a low maintenance, fast- growing perennial ground-cover, easily adaptable to sun or shade. This description should trigger alarm bells! Such plants can quickly take over garden beds and invade nearby natural areas, and they’re difficult to control and remove. Avoiding this problem by planting non-invasive alternatives (see below) is the best policy, but established patches of Lamium and other invasive species can be removed with a bit of effort. Yellow Archangel is particularly problematic as it often spreads into undisturbed wooded areas, forming thick mats and smothering the native plants that provide habitat for wildlife. Large areas can be severely impacted by the dumping of a single hanging basket. Other Lamium varieties (eg L. purpureum) also escape gardens, so if you’re set on growing any of these, please keep them in a contained area, away from the edges of woods or meadows, and be sure to deadhead the flowers.
