Allium ursinum umbel of six to 20 white flowers only, lacking the bulbils produced by some other "Allium" species such as "Allium vineale" (crow garlic) and "Allium oleraceum" (field garlic). It flowers in the British Isles from April to June, starting before deciduous trees leaf in the spring. The flower stem is triangular in cross-section and the leaves are broadly lanceolate similar to those of the lily of the valley ("Convallaria majalis"). It is native to temperate regions of Europe, from Britain east to the Caucasus. It is common in much of the lowland British Isles with the exception of the far
Botanical name also needs a connecting term (in the "Acacia" example above, this is "subg.", subgenus). The connecting term is not part of the name itself. A taxon may be indicated by a listing in more than three parts: ""Saxifraga aizoon" var. "aizoon" subvar. "brevifolia" f. "multicaulis" subf. "surculosa" Engl. & Irmsch." but this is a classification, not a formal botanical name. The botanical name is "Saxifraga aizoon" subf. "surculosa" Engl. & Irmsch. ("ICN" Art 24: Ex 1). Generic, specific, and infraspecific botanical names are usually printed in italics. The example set by the "ICN" is to italicize all botanical names, including
