--><p>R. A. Levin et al. (2004) found strong molecular support for Neoholmgrenia in a clade with Camissoniopsis and Tetrapteron. P. H. Raven (1969) found Neoholmgrenia (as Camissonia sect. Nematocaulis) to be one of the most distinctive groups in Camissonia by virtue of its relatively short (less than 10 mm), flattened capsules and densely clustered leaves near the tips of otherwise leafless stems. Reproductive features include: self-compatible; flowers diurnal; outcrossing and pollinated by small bees or flies, or autogamous and occasionally cleistogamous (Raven).</p>
