branched roots (Fig. 1.15a). This closely matchesPhacelia crenulata
Torr. (Fig. 1.15b) native from Colorado to Mexico.
- Fol. 51v.Phacelia integrifolia(Fig. 1.16).The phytomorph has blue
flowers on a scorpioid cyme and narrowly elliptic crenate leaves that
curl (Fig. 1.16a). The roots are brown and branched. This matches fairly
well with the variability ofPhacelia integrifoliaTorr. (Figs. 1.16b and
1.16c) which is native from Utah and Kansas, and south to Mexico. - Fol. 26r.Wigandia urens(Fig. 1.17).This bears what can be inter-
preted as bluish flowers on a scorpioid cyme with leaves that are green,
crenate, and obtuse (Fig. 1.17). This matchesWigandia urens(Ruis &
Pav.) Kunth very well (Fig. 1.17b), a shrub found from Mexico and
south to Peru. This is calledchichicaztle(D ́ıaz 1976) and also matches
