Crocus "cartwrightianus albus" bought this fall
contact (Fri, 09 Nov 2012 05:28:48 PST)

Hello Rolland,
Here is some aditional i formation from Jane Macgary written January
2001:
Further in the catalog (hoog& Dix), the plant grown in gardens as C.
cartwrightianus
'Albus' is referred to C. hadriaticus. Since C. hadriaticus is a hardy,
rapidly increasing, floriferous species, and also self-sows as much as any
crocus I know, perhaps "C. cashmirianus 'Albus'" is just a selection of C.
hadriaticus. The distinguishing feature between cartwrightianus and
hadriaticus is that the style branches of C. hadriaticus are "less than
half as long as the perianth segments and arise at a point well above the
throat" (Mathew), whereas in C. cartwrightianus the style branches divide
down in the throat.

From Brian Mathew: C. cartwightianus albus is, in fact, C. hadriaticus
it seems there are white C. cartwightianus but always with a small purple
throat like the white C. longiflorus I found have a few small linesin the
throat
