The first few comments did not say how to germinate, but there were pages of comemnts.
I found this online:
2. Palms; Banana; Coffee; Mini-Orange; Tea; Cycads and similar
All these items can take several months to germinate and are very erratic in germination. Soak for at least 2 hours in warm water before sowing. (After soaking the parchment shell on the Coffee seeds should be removed with the fingernail). \
Sow in Levington or Arthur Bowers (compost and place in the dark in a temperature of 75 degrees F, keeping the compost moist at all times, but not wet.
Inspect regularly and occasionally dig around in the compost with a penknife.
We normally sow our seeds just below the surface of the soilatid we have found that sometimes they make a very vigorous root without producing a shoot at all.
If you find a seed with a root then it should be excavated and potted up into a 3-4'' pot immediately when it will produce a shoot. Cycads prefer to be potted up into a compost of half sand and half peat. The Tea requires the above treatment but in a lower temperature of 60-65 degree F.
