If no one knows what this is supposed to be, take a look at the Xephs in the Expanded Psionic Handbook. These are the psionically illuminated trees mentioned.

Teaxi are a beautiful example of flora that is neither plant or fungus, but with traits akin to both and yet neither. They appear as large, gnarled trees of fibrous dark-brown bark that twists and curves the entire length. In evenly spaced sections grows equally gnarled and twisting branches from which grow opaque crystaline leaves ranging from milky white to smokey black and all shades of brown and umber in between. The veins throughout the foliage is alight with a gentle glow that extends far beyond the growth itself. Though it appears at first to grow in a chaotic fashion, if one is to look long enough one would notice the inherent fractal pattern to the growth that holds from the tip of the roots to the spread of the leaves.

Teaxi grow, not from seeds or clippings, but much as a mushroom, sending its tendril-like rootlets through the soil and gathering nutrients and moisture. Once it has the neccessary ammount it springs forth overnight into a half-sized sort of sapling that reaches full height within but a few weeks. They then continue to grow, but at a rate that approaches the geologic. All Teaxi are connected with one another, and form a collective, albeit minimal, intelligence.

They grow only in places open to the outside air, yet dislike sunlight. Though they are not harmed by it in any way, they will not grow in sunlit areas. This leaves them as a rare plant that thrives only in the shade of the deepest rifts and overhangs.

It is not certain how they came into existence, but most believe they were a breeding project by the earliest Xeph ancestors.

Teaxi share memories and sensations, but possess no real language. They stand some 20-25 feet tall on average, with a trunk about 8 feet in diameter.

Teaxi are barely aware enough of their surroundings to even recognize a threat, though they sense the presence of all about them. They merely defend even if attacked, possessing little ability for offense. Upon being harmed they immediately attempt to heal themselves, unless of some power type upon which energy conversion comes to life. Upon taking damage of this type they release it back at their opponents.

Deeplit (Ps):
A teaxi's crystaline florage continously releases a soft, wan radiance that illuminates a 60-foot radius with the brightness of moonlight.

Psi-like abilities:
Continuous/Inertial Armor (+7 AC*), Touchsight; 3/day Body Adjustment (6d12*), Sense Link; 1/day Energy Conversion, Suspend Life
Manifester level 8. Save DCs are Charisma based.
* Includes augmentation for the creature's manifester level and Empower Power feat.

Vulnerability to Sonics:
A teaxi takes half again as much (+50%) damage as normal from sonics, regardless of whether a saving throw is allowed, or if the save is a success or failure.
