Figure l. The distribution of Parmelia puUa s. lat. in Finland, according to herbarium specimens<br />
analyzed. Symbols: ! = strain | ('pulla", with stenosporic acid etc.), f = strain 2 ("pulla,,,with<br />
divaricatic acid etc.), O = strain 3 ("delisei", with glomelliferic acid etc.), A = chemically intermediate<br />
forms between "pulla" and"delisei".<br />
sions exhibited no clear, essential differences<br />
and are consistent with the few measurements<br />
made by me.<br />
Chemistry<br />
Esslinger (L977 p. 107-108 and L36) also<br />
reported on the secondary chemistry of the<br />
tara in question. In P. delisei he detected glomelliferic,<br />
glomellic and perlatolic acids, with<br />
gyrophoric acid (!) as an accessory compound.<br />
For P. pulla he reported stenosporic or/and<br />
divaricatic acids, with accessory gyrophoric<br />
acid (i), and very rarely perlatolic acid. Occasional<br />
unknown, accessory substances were<br />
designated TE-l and TE-3.
