SEASONED AND EXPERIENCED BOTANISTS are likely to approach the subject of identification by using definitive botanical works (floras) that rely on detailed keys, a thorough understanding of botanical terms, and a willingness to use descriptions rather than pictures to separate species. While this approach has scientific validity, in my experience it is not the way that the average floral enthusiast approaches the problem. Most tend to leaf through illustrated books to find suitable candidate species and then narrow down the field by scrutinising any closely related alternatives. This approach can succeed in most instances, especially if close care is paid to the detailed structure of the plant – leaves and fruits, as well as flowers – in addition to other factors such as flowering time, habitat preferences and distribution. I anticipate that this is how Complete British Wild Flowers will be used, initially at least, by most readers, although it will not take long for even the most inexperienced person to be able to detect similarities among plant family members, hence narrowing down the options at a stroke. Nevertheless, for absolute beginners, I felt it would be useful to provide a few pointers to lead in the right direction. I have concentrated on flower families where, in most species, there are sufficient similarities to justify generalisations. Strikingly unusual flowers, and species without large family ties, are not included in the following series of short cuts. I have used flower structure, such as the number of petals, as an initial guide. Note, however, that within several of the families identified, one or more rogue species may defy the family character and will not fall into the appropriate category. For example, although Tormentil is a member of the rose family (characterised by flowers with five petals), its flowers have just four petals.
SHORT CUTS TO FLOWER IDENTITY
3-PETALLED FLOWERS
WATER-PLANTAINS – equal-sized petals; white or pinkish petals; aquatic or marginal plants; see pp.
ORCHIDS – flowers comprising 3 petals plus 3 sepals, the latter often petal-like in colour and shape; the lower petal often takes the form of an enlarged or elaborate lip; see pp.
4-PETALLED FLOWERS
CABBAGE FAMILY MEMBERS – relatively small flowers; equal-sized petals; flowers often in groups; white, yellow or pinkish depending on species; see pp.
BEDSTRAWS – tiny flowers; equal-sized petals; flowers often in frothy heads; white or yellow depending on species; see pp.
SPEEDWELLS – relatively small flowers; unequal-sized petals; blue, purplish or white depending on species; see pp.
WILLOWHERBS – relatively small flowers in most species; equal-sized petals; flowers in open heads; pinkish, red or white depending on species; see pp.
POPPIES AND ALLIES – relatively large and crinkly, equal-sized petals; flowers usually solitary; red or yellow depending on species; see pp.
5-PETALLED FLOWERS
WATER-CROWFOOTS – equal-sized petals; flowers usually solitary; white petals; aquatic; see pp.
SUNDEWS – tiny flowers with equal petals; in spikes but usually only one flower opens at a time; bog plants with sticky, red leaves; white petals; see pp.
BUTTERCUPS – equal-sized, often shiny petals; flowers usually solitary; yellow; see pp.
ROCK-ROSES – equal-sized, crinkly petals; flowers usually solitary; yellow or white depending on species; see pp.
ST JOHN’S-WORTS – equal-sized petals; flowers in open heads in most species; yellow but marked with small black dots or streaks in some species; see pp.
