Nice to have you back, Mark.
I am a word-aholic, and I had to look up "urceolate" in the book I have by James Harris and Melinda Woolf Harris,Plant Identification Terminology An Illustrated Glossary. A very worthy purchase (or gift purchase) for any serious gardener.
Urceolate. Pitcher-like; hollow and contracted near the mouth like a pitcher or urn. Figure 1411.
