Helleborus niger
Helleborus sp.
(note: the symbol "sp." standing for "species" denotes that the species is not indicated - Only the genus is written)
Here is a note on the etymology of Helleborus according to which the word may be derived from ἑλλός meaning fawn (little deer) and food.

Here is another article from The Guardian on Hellebores (a significant number of articles has been publised by the Guardian on these plants).
Excerpt:
Note: Refers to Helleborus orientalis – Lenten rose (Wikipedia N.B. most of the Lenten hellebores in gardens are now considered to be H. × hybridus)
"Winter would not be winter without this little ritual and my delight in hellebores never diminishes. Flower in winter is precious, and I actively look forward to the hellebores. Gathering strength when nearly everything else appears to be sleeping, the new growth pushes free from last year's rosette of leathery leaves, rising up elegantly and holding the flowers free in a space clear of foliage."

As mentioned at the page "Taxonomy of Species", the "Catalogue of Life" is the official resource for the taxonomy of different species. If we browse the taxonomy tree for Kingdom Plantae as described previously:
Access the monthly or annual edition from the page http://www.catalogueoflife.org/
and the respective buttons.
To view the taxonomic tree select it from "Browse" as follows (red rectangle):
Here are the corresponding phyla:
Phylum Anthocerotophyta • 51 spp
Phylum Bryophyta • 13,373 spp
Phylum Marchantiophyta • 788 spp
Phylum Tracheophyta • 335,609 of 339,356 est. spp (99%
As we see, the first and third phyla have a small number of species. In the past, the first three were grouped together as Bryophytes but now they are split.
As mentioned in wikipedia:
https://en.wikipedia.org/wiki/Bryophyta
Bryophytes, a group of plants formerly regarded as a single division but now split into:
Vascular plants (from Latin vasculum: duct), also known as tracheophytes (from the equivalent Greek term trachea) and also higher plants, form a large group of plants that are defined as those land plants that have lignified tissues (the xylem) for conducting water and minerals throughout the plant.

If we browse the taxonomy tree for phylum Tracheophyta we will see the following classes:
Class Cycadopsida
Class Equisetopsida
Class Ginkgoopsida
Class Gnetopsida
Class Liliopsida
Class Lycopodiopsida
Class Magnoliopsida
Class Marattiopsida
Class Pinopsida
Class Polypodiopsida
Class Psilotopsida
Let us try to understand these.
