Growing on limestone soil. 4,000 to 7,500 feet. Map No. 4. April to June. This species has been contused in the past with C. ohlata. but differs from it in the larger corollas which are strongly helerostyled. the more compact inflor- escence, and the nutlets which are only finely rugu- lose or tuberculate. More collections of this laxon arc badly needed in order to determine its exact geographical range. 5. Cryphintha crassipcs Johnst. Cryptantha crassipcs Johnsi. Joum. Am. Arb. 20:.107. 143^).
