penaliasp., possiblyP. delphinifolia(Rydb.) McVaugh (Fig. 1.11c). Is
this a hybrid phytomorph, that is, did the artist paint a combined image
based on two species mixed together?
- Fol. 40v.Smallanthussp. (Fig. 1.12).This folio contains two phyto-
morphs of the same plant, vegetative and flowering (Fig. 1.12a). While
quite definitely a member of the Asteraceae, the genus is less obvious.
With bluish petals, reddish involucre, palmately compound leaves, and
tuberous roots, this seems to fit aSmallanthussp. It resembles some-
what the leadingSmallanthusspecies cultivated today, the edible yacon ́
(S. sonchifolius(Poepp.) H. Rob.), which is native to western South
America (Figs. 1.12b and 1.12c).
H. Boraginaceae
- Fol. 47v.Cynoglossum grande(Fig. 1.13).This phytomorph has
terminal blue flowers of six to seven petals with a raised white cen-
ter, prominent cauline leaves, broadly elliptic basal leaves, and broad
branched brown roots (Fig. 1.13a). This matches the variability of
Cynoglossum grandeDouglas ex Lehm. except that this species has only
