>>What about evergreen bulbs such as Crinum asiaticum which does not undergo a dormant period, can they be considered geophytes? What about Aloe modesta which has a swollen underground "bulb" comprising of leaf bases? Is this a succulent geophyte??? I can assure you all that as a very poor geophyte grower I have often demonstrated that the evergreens can indeed "survive[s] an unfavourable period" ! ;-) Seriously isn't it likely that they evolved that way to keep in reserve coping with unusual unfavourable conditions ?
