two changes at once
Why does a search for cheelantes find nothing?
Both a vowel and a consonant are off: it is cheilanthes.
two changes at once
Plant catalogues and herbarium databases match on the string rather than the sound, so a name with two letters changed usually returns nothing at all instead of a near miss. It helps to know which half of the word to check first. The ending, -anthes, is shared with a handful of other genera and is stable. The opening, chei-, is the part almost everybody gets wrong.
