Nutlets minutely tuberculate to nearly smooth, dull to slightly shiny. Corolla variable in colour but never blue (native) = S. Stem distinctly winged, wings decurrent for more than one internode. Largest flowering stems branched, prickly = S. Flowering stem unbranched, hirsute but not prickly = Symphytum grandiflorumĬorolla when open blue or pink below and white above, sometimes flushed with red below (reddish in bud). Plant not stoloniferous, with vertical rootstock = 3Ģ Corolla pale yellow when open (reddish in bud). The account for the British Isles (Stace 2010) is particularly helpful and includes several supplementary (notho-) taxa.ġ Plant with creeping rootstock, often stoloniferous, decumbent or procumbent = 2 In addition to the species and hybrids treated in this account several others have been recorded in the wild in neighbouring territories. Several species are cultivated as ornamentals (e.g. is a common native species (Lambinon & Verloove 2012). Its center of diversity lies in Turkey where 18 species are native (Hacıoğlu & Erik 2013). 35-40 species, native to Europe, the Mediterranean area and the Caucasus. The leaves are simple (i.e.Symphytum is a genus of ca. There is one leaf per node along the stem There is a gradual change in appearance of the leaves from the base (or near the base) of the plant to those from further up on the stem, with leaves progressively changing as one moves higher on the stem (often becoming shorter, or less toothed/lobed, and/or with shorter petioles). The leaves are simple (i.e., lobed or unlobed but not separated into leaflets) The leaves are green, with an expanded blade and a leaf-like texture The leaves drop off in winter (or they whither but persist on the plant) The major veins form a net-like pattern due to splitting and rejoining The upper side of the leaf blade is relatively uniform in color the leaf blade is ovate (widest below the middle and broadly tapering at both ends).the leaf blade is lanceolate (lance-shaped widest below the middle and tapering at both ends).the leaf blade is elliptic (widest near the middle and tapering at both ends).The edge of the leaf blade is entire (has no teeth or lobes) the base of the leaf blade is cuneate (wedge-shaped, tapers to the base with relatively straight, converging edges), or narrow.The fruits do not have thorn-like defensive structuresįinal leaf segment length (compound lvs only)įinal leaf segment length to width ratio (compound lvs only)įinal leaf segment width (compound lvs only)Īlternate: there is one leaf per node along the stem The plant has axile placentation, in which the ovules are attached where the septa of a compound ovary are united, usually on the central axis, or to the septa themselves the ovary or fruit does not have a stipe.The fruit is a schizocarp (when dry it splits into sections, each holding one or more seeds) The fruit is dry but does not split open when ripe the stamens are attached at or near the bases of the petals or tepals.The sepals do not have appendages on them The petals of the flower do not have folds or plaitsĪll the flowers have both carpels and stamens (synoecious) The petals are thin and delicate, and pigmented (colored other than green or brown) The flower includes two cycles of petal- or sepal-like structures The ovary is above the point of petal and/or sepal attachment There are five petals, sepals, or tepals in the flower The flowers are all or nearly all arrayed on one side of the inflorescence axis or branches of the inflorescence The petals or the sepals are fused into a cup or tube the style is narrow at the tip and unbranched.the style is knob-like at the tip, and unbranched.There are two or more ways to evenly divide the flower (the flower is radially symmetrical) The flower has a superior ovary, and lacks a hypanthium There are no cleistogamous flowers on the plan There are two or more ways to evenly divide the calyx (the calyx is radially symmetrical) The anthers have narrow slits or furrows that run lengthwise along the anthers
