Dyckia Brazil: Dyckia argentea?

Dyckia argentea?
Due to problems in its description Dyckia argentea is an invalid name.
But this here is the closest argentea possible to what should be the real thing.

Dyckia sp, what does this mean? ...and what else?

Dyckia sp is the very same as Dyckia species, in fact short for Dyckia species. It refers to an unnamed Dyckia species.

A Dyckia sp can not be a hybrid Dyckia and never a Dyckia you do not know the name but a nameless Dyckia species. The fact that you do not know the plant it does not mean a nameless one.

A new Dyckia species must be published in order to have its name valid. This obligation doesn´t counted on Iternet publications as The World Wide Web didn´t exist and publication meant : journals, books, magazine, scientific report magazines.

Nowadays nothing is better published than in the WWW.
Publishing means getting public and there is nothing equal nor close to the WWW.

Public means everybody not just a bunch of selected guys.
These are mates, collegues, fellows not public. Here people publish new Plant species on very restricted magazine or very specialized magazines and assume as published. Publishing means everybody who is willing to know of it. Also the world doesn´speaks Portuguese, nor spanish and less than this doesn´t understand old Latim ( Not even those who publishes a new species. They rely on claves and many mistakes are made.) Today publishing means WWW!!! Today it means English!! If a new species is published here in Brazil it must be in Latim as in any other place on the Earth, Portuguese and for God´s sake also in English and entirely not a sinopsis only. Publications with a very restrictec and exclusive public is out of question. Publications with on purposal omitted data is also out of question and not valid. A bunch of readers is not public. A group of readers are collegues never public!!!Public is WWW and your reader may be in Reykjavick or Auckland, Rio or Tokyo and everywhere in between. Portuguese is a lovely sounding language. It makes feel home...but who is going to undertand me in ...in...everywhere else besides people which countries speak Camões´ language? English, English for Gods´sake.
Also there is no sense publising without precise data.
Preservation means showing, educating not hidding an less yet iluding.
What Light is for if it doesn´t Brighten up high above everything? Light is to iluminate or it is not Light and if it isn´t Light it isn´t Science!

Species and Hybrids understand their names

Understand Latim names. Latim names identify species. Usually they have two words. The first one begins with a Capital letter and the second doesn´t. The second identifies the species and the first tell the genus it belongs to.
e.g. Dyckia brevifolia
Dyckia is the genus and brevifolia the species (brevi = short folia = leaf)

e. g. Dyckia MammaMia
Hybrid plant , the second name also begins with a capital letter.
