Much confusion has been caused by the large number of inter- 
mediates between M. longiflorus and M. puniceus. That the 
plants hybridize has been demonstrated by experimental work 
already diseussed. "These intermediates can easily be separated 
into four groups, of which the following two agree closely with 
known hybrids. 
108b. M. longiflorus x M. puniceus 
Stems densely glandular-pubescent ; leaves oblong or lanceolate, 
obtuse, pubescent below; calyx 2-2.5 cm. long, puberulent, often 
viscid-villous at the base, the upper part not widely inflated; 
corolla 3.5-5 em. long, dark red, lobes .5-1 cm. long, truncate, 
crenate. 
Distribution: southern California from Los Angeles Co. to San 
Diego Co. 
Specimens examined:

The corolla of this hybrid is similar to that of M. puniceus 
except that it is longer and has a broader limb. Тһе upper hal 
of the calyx is inflated, resembling that of M. longiflorus. 
108c. M. longiflorus x M. puniceus. the 
Calyx glandular-pubescent, more or less viscid-villous оп 
lower part, not expanded above the middle; corolla кете 
long, salmon color, limb 2.5-3 cm. wide.
