The arils should have AVI in the dark aril spot area.


I examined a specimen from Kalifa's Robe yesterday. The tissue was not from the signal area. Instead it was taken from outer areas of the falls away from the spot. It contained spheroid structures I believe to be AVI. However, the fluid they contained was the same general color as surrounding fluid in the cells and the "sphere" itself was present in most all of the cells. I will check a "spot" today.

I know with certainty you could use a better helper. I've been in a botany book for some time now familiarizing myself with plant cell structure and cell components.

Right now Kalifa's Robe looks more like a JI from all the rain over the last two days.

I also examined azalea outer petal tissue. It had what I think to be the AVI structures in a few of the cells. Maybe one out of ten. They too appeared filled with the same fluid color (bright pink) as the surrounding cell. When I examined the same slide today (about 24 hours later) the suspect AVIs were a deep blue purple. The fluid in the surrounding cell had degraded to an almost white color.

No cell structure at all could be discerned in the older Kalifa's Robe (more than 24 hours old) sample.

As a point in passing, I took cross sections of the beard area with an Exacto knife to examine them. I think Neil correct in that beards are single cells. Interestingly, some of the beard hairs (single cells) do branch from low on their vertical axis. Not all or many. Each beard hair also exhibits "thorns" much like a rose stem on a smaller scale. I find myself wondering if the branched beard hairs might bare some relationship to space age expression in tall bearded irises?
