“…As with other perennial species in the genus Lotus, Zandstra and Grant (1968) suggested that the flowers of L. pinnatus required cross-pollination to set viable seed. Given the bright yellow appearance of the flower and the wide keel that serves as a suitable landing platform, flowers of L. pinnatus appear to be adapted to bee pollination.…”

“…Other factors, such as slope and aspect are variable and do not appear to be critical in defining suitable habitat. In British Columbia, the elevation for this species ranges between 40 m and 150 m. Zandstra and Grant (1968) studied the biosystematics of native and introduced Lotus species in Canada and reported that although many of the Old World species are polyploids, none of the North American species examined exhibited the same trait. North American Lotus species have a base chromosome number of 6 or 7.…”

“…Evolution in angiosperm reproduction has frequently occurred with a decrease in basic chromosome number, a shift from an outcrossing (crosspollinating) to an inbreeding (self-pollinating) reproductive system and a shift from a perennial to an annual habit (Stebbins 1957). On this basis, Zandstra and Grant (1968) considered L. pinnatus and L. formosissimus to be more primitive than the annual species.…”

Conservation Evaluation of the Bog Bird's-foot Trefoil, Lotus pinnatus, in Canada

In Canada, Bog Bird’s-foot Trefoil, Lotus pinnatus, is confined to vernally wet meadows, creek margins, ditches and seepages, where underground water comes to the surface. Seven localities, within a small area on the east coast of Vancouver Island near Nanaimo, British Columbia, have been confirmed in recent years. At two others it is considered extirpated. The lack of protection on private land, alterations to hydrology, and erosion arising from intensive recreational use of primary habitat by off-road vehicles as well as the appearance of invasive, species are the main concerns for British Columbia populations.

The native form of Lotus corniculatus L. in the north of Europe is a prostrate plant with small leaflets and short internodes. Morphologically different plants with erect growth habit, large leaflets, light keel petals and hollow stems have been introduced in the seed mixtures sown on new roadside verges. The alien plants are being studied to determine their persistance and the effect they may have on the adjacent native populations. Variation within and between two groups of alien plants growing near Hull has been measured. Discriminant analysis of 11 characters showing continuous variation gives a quantitative separation between the two groups of aliens, separates alien from native plants and can be used to detect hybrids between the two forms.Le lotier spontané du nord de l'Europe est une plante généralement prostrée a petites feuilles et entre-noeuds courts. Des plantes morphologiquement différentes (port érigé, caréne pale, feuilles larges et tiges plus on moms creuses) ont été introduites lors du semis des remblais de routes nouvellement construites. L'étude de ces plantes introduites a pour objectif de determiner leur persistance et l'effet de leur presence sur Ia population de plantes autochtones. Les plantes introduites sont comparées d'une part avec les plantes autochtones et d'autre part entre elles lorsqu'elles proviennent de sites différents prés de Hull. Une analyse discriminante sur onze caractéres biométriques a permis de quantifier Ia distance entre les groupes de plantes introduites, de mettre en evidence Ia presence d'hybrides entre autochtones et introduites.

“…However, these compounds were not quantified, and none of the compositions were associated with a specific plant phenotype. Lotus species also accumulated cyanogenic glycosides and 2,3-diaminobutanoic acid (L. tenuis, L. australis and other Lotus species), alkaloids (L. garcinii, L. corniculatus, and L. uliginosis), 4-(3-methyl-2-butenyl)-tryptophan (L. subglauca), and homoarginine (L. helleri) (Grant and Sidhu 1967;Grant and Zandstra 1968;Zandstra and Grant 1968;Chapman and Hall, 2004).…”

K. 2008. Variation in morphology, plant habit, proanthocyanidins, and flavonoids within a Lotus germplasm collection. Can. J. Plant Sci. 88: 121Á132. Lotus species collected from a range of geographical locations were evaluated for relationships between plant habit and size, leaf proanthocyanidin (PA) content, flower colour, stem colour, leaf colour, trichome density, and geographic origin. No relationships occurred between leaf PA concentration and morphological trait or collection site. Trichome coverage was moderately correlated with plant size (r 0(0.70). Several accessions, e.g., L. angustissimus L. and L. castellanis Boiss. & Reut., consisted of small, trichome-covered plants distinct from the large, glabrous plants typical of the model species L. corniculatus var. japonicus ecotype Gifu B129. These two morphology types were also represented among the tan mutants of Gifu B129. Due to the importance of trichomes and PA in plant defence, PA composition was compared between L. angustissimus and tan1 (both representing the small trichome-covered phenotype) and ecotype Gifu B129 and tan2 (both representing the large, glabrous phenotype). Both the tan1 and tan2 mutants accumulated substantial amounts of leaf PA similar in size to the small oligomers recovered from leaves of L. angustissimus. PA polymers were undetectable in Gifu B129 leaves, while floral PA extracts of this ecotype included a much larger PA polymer. Flavonoid composition in leaves of tan1 and L. angustissimus was complex, and differed from the simple profile in Gifu B129 leaves.
