Dyckia estevesii...some hints on it:
a- Its flowers do not pollinate by themselves.
It seems simply it need a special pollinator agent missed here in the South.
b- Its flowers do not open allowing an insect to get in but just a insect proboscis can get in. the tiny hole is kept closed to any proboscis if the temperature is not hot enough for this to happen.
c- To get seeds one needs to hand pollinate. Without this help we rarely get any seed.
d- Seeds are all fine and germinate well and no distic form is obtained. We get normal round plants.
e- Trunks can be extremely long with more than 4 meters, prostrated and snaking on the ground.
f - The plant produces innumerous sprouts along the trunk and these sprouts produce sprouts the continue to proceed so. In years all terrain is occupied by beautiful isolated plants.
g - A first glancer would take it as species once in nature.
h- A keeper, a cultivator soon realizes this is not a species.
Dyckias are so, intriguing and can easily foll you. If one goes too thirsty to the pot this is broken and the water is wasted. Dyckias were not taken too serious and were side findings by those who searched the wilderness for cacti and orchids. Describer outside Brazil could not realize these side finding were extremely special as they had to rely on specimens brought from the wilderness by bushmen. Describers imagined or took Dyckias as a normal plant not plants the needed to be visited many times in wilderness and cultivated for many years before any attempt of describing is done.
Dyckia...we are still to learn a lot...
