I here do not talk about the men but about their work.
Dyckias are not a matter of finding it and describe it...No way!!!
They must be taken more seriously and not just a side finding. One must visit it at home many times and during different seasons and cultivate the plant as much similarly as possible to the climate it is used too.
No wonder that is so up today as not long ago new plants were only described in Europe. Famous Botanic Gardens destroyed here in Santa Catarina our native populations of Laelia purpurata. Tons of them were send to these BG only to die during the sea journey or within badly equipped warmed up rooms (they used charcoal). Recently our beautiful cactus Uebelmania pectinifera was devastated in nature up to the point we can never find big ones anymore as all of them were removed from nature (from places a goat has to be very skilled to reach) in an attempt to promote the elevation of its price in international trade. In two collections one here in Brazil and one in Europe we see where those adult bicentennial cacti are.
Have you ever seen this...live and alive?
