I ordered some bulbs from South African enterprise.
There are several forms for a species and it's like

Brunsvigia orientalis "nardouws giant" 
Haemanthus humilis subsp. humilis Giant Gaikaford form

But I don't know how to notate them correctly
These forms are not officially named cultivars.... right?

So it shouldn't be notated as Brunsvigia orientalis "Nardouws Giant"
Can I just say it's Brunsvigia orientalis Nardouws Giant form?

Or tell me other correct notations!

Boophone disticha, Brunsvigia orientalis, B. marginata, B. pulchra

B. disticha didn't have root when I received the bulb but it had some green leaves back then.
Now it's all gone brown. Brunsvigia have root.
I live in South Korea and now they don't have any leaves, should I stop watering?
Please let me know when to start watering again.
These bulbs are still firm but I think they got stressed while repotting them and the temperature has been like 10°C.
