Hey @Dave - I do not see this listed in your dictionary:

Stomium: the thin-walled cells of the annulus marking the line or region of dehiscence of a fern sporangium. 2 : the opening in an anther usually between lip cells through which dehiscence occurs.

I would add a photo to it, if it was listed.

Thanks, I added it. https://garden.org/nga/diction...

Thanks! Photo added!

Not noted in dictionary:

mucronate - term used when describing petals, meaning an abruptly tapering point such as at the end of
a petal.
ending abruptly in a short sharp point or mucro

absorbed - term refers to daffodils having multiple names that have been determined a single cultivar by accreditation sources (American Daffodil Society a/o Royal Horticultural Society). This typically happens to historically older daffodils.

dictionary doesn't note this
perianth - in daffodil world, this term is the same as petal

@jmorth

mucronate: https://garden.org/nga/diction...
perianth: https://garden.org/nga/diction...

The 1st one is there, but the 2nd term doesn't note the perianth equals the petal (in the world of daffodils). or maybe the explanation is just too 'botanical' for me.

All handled @jmorth

Thankyou

@dave
another one:
guttation - The exudation of water from leaves as a result of root pressure.
the secretion of droplets of water from the pores of plants.

@jmorth guttation is definitely one that needs to be in the dictionary!

Guttation - the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface.

Thanks, it's added!

@dave
I've a pic to show for first defination of guttation -

guttation - The exudation of water from leaves as a result of root pressure.
the secretion of droplets of water from the pores of plants.

Jack, you should upload you photo to the dictionary entry: https://garden.org/nga/diction...

I thought I had a few pic's of guttation but haven't been able to locate them on my laptop so they must have been in with photos I lost when my computer crashed a couple of years ago.

Interesting new definitions. Thanks for the info.

@plantladylin
The explanation there sounds like it applies to plants outside, the pic is a houseplant and goes more with my definition

The definition in the learning library possibly needs additional wording. I know guttation happens in a few different types of plants but I never knew it had anything to do with root pressure but just found this page with more information/definitions of both transpiration and guttation in plants: https://www.majordifferences.c...

Interesting. Probably leads to more new words for dictionary.

@dave
Another word:
Hydathodas - water stomata
structurally modified portion of a leaf used to send excess water out in liquid form

stomata (not listed either) - any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width which allows movement of gases (or water) in and out of the intercellular spaces.

Another definition to add:

Areole (Areola):

- A condensed, lateral, circular or oval shoot resembling a cushioned disc from which branches, leaves, spines arise.

- A sunken cushion representing a condensed lateral shoot from which spines, branches, and flowers arise in cacti. Areoles may occur either singly on tubercles

@Dave, We have the definition for exelate listed in the dictionary:
exalate (ehks ay'layt)a. In botany, lacking wings or winglike appendages; not alate.

Should the word alate be added?

alate - adjective, having a wing or wing-like extensions. In botany alate refers to winglike structures on some seeds that use wind dispersal, or it may be used to describe flattened ridges which run longitudinally on the stems.
