Advice on seed I have to sow when it warms up???

These are the Mamm. seeds I have to sow when the weather warms up some (or I get off my butt and make my hotbed...which ever comes first ) and I'm looking for tips on ones that might require a 'non-standard' approach:

Mamm.:

guelzowiana *
duwei
boolii
baumii
flavicentra
sanchez-mejoradae
senilis (R.S. 801 El Salto)
discolor
theresae *
perezdelarosae *
albicans
fraileana
meigeana
tetrancistra
hahniana
vallensis var brevispina
bombycina
pottsii
lenta
longimamma
prolifera texana
plumosa
picta
occidentalis
sinistrohamata
tesopaciensis var. papasqiarensis
bocasana
candida
mazatlanensis
uncinata
surculosa
compressa
grahamii
and
schumannii (*maybe... don't know much about this one)

The ones with a * are the ones I'm anticipating trouble with. Is there anything I should know about any of the others to improve my odds?

(I'm also thinking a few of their names may be incorrect and would grateful of any 'updates')
