This and the next species (4. tridens (Lindl.) Schitr.) 
are clearly closely allied and further material may show 
that they are conspecific. 4. dolabriformis has broader 
leaves, more flowers in the inflorescence, slightly larger 
flowers and a longer spur than 4. tridens, but it remains 
to be seen if these are valid distinctions or merely rep- 
resent plants of different degrees of robustness.
