Phalaenopsis-kapuasensis-2023-02-20 *SITF confirms this plant is Phalaenopsis kapuasensis (Jun 2023).
This species is related to P. rundumensis, but P. kapuasensis has shorter sepals and petals, not more than 1.7-cm long, a lip with a hairy midlobe and different shaped side lobes. The key characteristic sepatrating the two is the presense of short, thick hairs on the upper surface of the lip midlobe, which can be easily seen on this plant. This plant exhibits the denticulate bristles on the lip which are unmatched by other species as well as the odd structures at the end of the side lobes. Flower size matches the description and the flower matches the photos in the IOSPE, OW and many photos in orchidroots.com.

Phalaenopsis-lueddemanniana-2022-06-24 *SITF has determined this plant to be Phalaenopsis cf. lueddemanniana (May 2023).
This plant has enough similar features to be considered Phal. cf. lueddemanniana (cf. a Latin abbrev. to describe a specimen that is like or similar to a taxon, but with a degree of uncertainty); however, there are some features which also suggest it could be an intergrade hybrid. For example, the lip should not be spade/trowel-shaped, but rounded and flat, not folded in the center; the widening of the thickened patch at the end of the lip midlobe could possibly be from a different species. This plant does show the trichomes on the apical area and the dense papillae on the posterior callus. Also, Christenson states, this species, even after the exclusion of several former species, is still variable.

This form of P. bellina exhibits narrow petals that reach upright rather than horizontal, resembling a stick figure with its hands up like the Chinese character for fire,  The form is normally highly colorful, however this plant was recognized for its rare, pastel pink color form, but it has the key characteristics of f. murtoniana.***

Phalaenopsis-pulcherrima-var-laotica-2021-09-06***Confirmed as Phalaenopsis pulcherrima (Laotian Form) (May 2022); it is incorrect to label this as var. laotica since this subspecies has not been formerly recognized taxonomically; it was formerly identified as Doritis pulcherrima f. laotica, but the subspecies was never transferred to Phalaenopsis, so it is synonymous with P. pulcherrima; the "Laotian form" of P. pulcherrima is distinguished from the type by its diminutive size; to separate this plant from the type, the label (Laotian Form) was added.***

Phalaenopsis-bellina-Fernbrook-JC/AOS-2021-08-24***SITF has determined after reviewing the challenge (July 2022) that based on the history of the Phalaenopsis bellina-violacea complex and some questionable attributes in color and form of this cultivar, it could possibly be a hybrid, since P. bellina and P. violacea were at one time considered the same species and there is no way to know if this plant is a pure P. bellina due to line breeding with parents that historically might have contained P. violacea which was considered synonymous.***
