Discussion
Crataegus tecta occurs from Mississippi to western Georgia and northern Florida. The species is fairly common in southern Alabama, and there is one somewhat atypical example for Tennessee, the second most northerly record for the series.
The typical form of Crataegus tecta is a distinctive morphotype in ser. Pulcherrimae. Compared to the somewhat similar C. incilis, the leaves are proportionately wider and have fewer lateral veins, and the anthers are cream or ivory. One specimen of C. tecta has a relatively densely pubescent inflorescence and, if correctly identified, this is the only such example for the series. Some specimens with conspicuously acuminate and slightly reflexed lobes are provisionally referred here rather than to C. venusta. Crataegus opima is usually the species most similar to C. tecta, lobe size and shape being the main discriminators. Crataegus austrina Beadle, with a narrower leaf form, is possibly the same.
