Microgravity
Typical picture of a dendrite: Notice how the branch on the left has no arms coming off the top. This is because of the convective forces (hot liquid rises) that the top of the branch is not solidifying (growing arms) like the bottom, cooler area. The is a gravitational effect. This does not happen in space.
