The stringers don't need to reach all the way to the stem. It's a lot easier if they don't and the shape goes into some compound curves there so it doesn't really need them for support. The last rib at each end is too sharp a vee to bend, so it's two sticks. It would be better to use curved sticks, putting a bit more volume in the bows. The willow ribs were irregular, but once lashed into a mesh with the stringers, the whole shape got nice and fair. Willow isn't the only species that works for ribs, and unless you're cutting when the leaves are out you probably won't know what species it is anyway.
