Other info. - This small plant is rare in Missouri and reaches the northwest corner of its geographical range in the boot-heel of the state. The plant is very easy to ID in the field because of its spreading inflorescences, tiny white flowers, and 2-carpellate fruits. It is much more prevalent in states to the southeast of Missouri.

Family - Ranunculaceae
Stems - To +15cm tall, from tuberous roots, herbaceous, often reddish, thin, (+/-1mm in diameter), erect, single or multiple from base. Plant completely glabrous.
Leaves - Opposite. Basal leaves biternate to triternate, appearing at anthesis, petiolate. Petioles to +12cm long. Leaflets shallowly 3-lobed or just notched, to +2cm long, +1.5cm broad. Cauline leaves forming an involucre at base of umble rays, ternate. Leaflets similar to those of basal leaves.
Inflorescence - Terminal umbel with 1-4 rays. Rays to +3cm long, very thin. Single flower terminating each ray.
Flowers - Apetalous. Sepals petaloid, 5-8, typically white but also pinkish-lilac, to 12mm long, 6mm broad, glabrous, rounded to subacute at apex, obovate to ovate. Stamens many. Filaments to +/-5mm long, white, glabrous. Anthers yellow, to +1.5mm long. Carpels 4-15. Achenes 8(10)-ribbed, to 5mm long, 2mm in diameter, fusiform, glabrous to pubescent.
Flowering - March - June.
Habitat - Dry open or rocky woods, upland slopes, ridges.
Origin - Native to U.S.
Other info. - This small plant is common throughout Missouri but is easy to confuse with another member of the Ranunculaceae, Isopyrum biternatum (Raf.) T.&G.
They can be differentiate by the following: Isopyrum inhabits low woods and moist soils, has smaller flowers with only 4-5 petaloid sepals(which are always white), and has fibrous roots and alternate leaves.
A. thalictroides gets its species name from the fact that its leaflets resemble those of the genus Thalictrum, which is also in the Ranunculaceae. "thalictroides" means "looks like Thalictrum."
Steyermark lists three forms for the plant in Missouri. Form thalictroides is the most common and is described above. Form chlorantha Fassett has sepals which are all green and foliaceous. Form favilliana Bergseng is double-flowered with all the stamens and pistils petal-like.

rebeccamee：Your one seems to have elongated leaves and stem which is the result of lacking sunlight and overwatering it. You may put it outside to get more sunlight but it needs time to adapt to the new environment. Never overwater it again and if the root is still ok it will be getting better.
Ueca：I support the idea to give it more sun.
If the base of the stem starts showing bluish-black and gets mushy, perform a beheading.
sarajordan2993：Im a few days late in seeing this . As for watering ... i judge mine by the soil . I stick my finger into the soil to about an inch then take it out . If there is soil on your finger , or it feels damp ... its not quite ready for watering . If they are going to be placed outdoors , make sure to acclimate them into the sun . if this isnt done , it could result in a sunburnt succ . Give him a very good watering when he’s dry . to the point where the water is draining out of the bottom . let me know if you have any questions/concerns 😊 im always willing to help
AhhOh坏丫头：sorry I also don't know how to do.Maybe he needs more sunshine.

Its hard to believe after only two months, that my jade plant has grown exponentially this much larger ! I even had to change the pot size so it could have more room to grow :)

Why are so many leaves drying out? It also seems like the plant is not growing; buds will only come out a little bit before hardening and drying. What can I do to make it healthy?

meriunkat：how much do you water it? if they are hardened and falling then it needs more water..
Ueca：It may be some kind of disease. There is a rigid white coat on some of the stems.

The growth habit of The arrow feather arrowroot.
originating from Brazil . It likes a warm and moist growth environment and prefers semi shade. It is shade resistant plant, so it is more suitable for indoor breeding. When indoors, it can be placed in a relatively bright place where it can be placed in a less light room and can grow normally.
The arrow feather arrowroot will generally choose loose and fertile and well drained soil.
