[Taxacom] canaliculate

Ken - interesting thought about a channel as more u-shaped and canaliculate
as more parabolic (as more of a groove than channel?). This illustrates
Alan's caution over descriptive precision. It's nice to have one word in
place of many, but of course that is useful only where the single word is
readily known and meaningful. And one would wish to avoid colloquial terms
since they can lack that generality. In this case the channel appears to be
more u-shaped than parabolic, and the channel might be considered partially
closed as the side curve inwards slightly. At least I will have
illustrative reference for the description which should make the actual
shape obvious, however characterized. Thanks again for the feedback on this
obscuria.
