Flower help?
Do you mean the receptacle (for the thick part of the stem??) . The recptacle is the base of the flower



Sepals are the green bits around the flower (for protection of the growing flower bud)
Reply:I'm not exactly sure what kind of plant you are talking about, but look at the image on the page at the link. Does your plant grow in a similar way to this?



The leaves at the bottom of the plant are called "rosette leaves" for obvious reasons, they form a ring or rosette. Lots of plants do this, but some of them (like Dandelions) only produce a flowering stalk from the center, while others produce a leafy stem that bears flowers. The leaves up the stem are called "cauline leaves" (derived from the Latin term for a stem) but we don't use a word related to that for the thick part of the plant stem.



Stems are called various names depending on their type. A lot of them are just called "stems" but when they hold up a tree, they are called trunks. Sometimes a stem is called by a generalized name "axis" or, if it is a mostly bare stalk holding up a group of flowers, it can be called a scape.
