History of Anathallis Obovata
Since Barbosa Rodrigues created this genus, Anathallis has never been taken seriously by taxonomists, who have instead preferred to group all the species under one large genus that could contain species with the widest variety of morphologies without running the risk of misidentification.
As a result, this genus went unnoticed for over 110 years until Fábio de Barros published a brief review of a few Brazilian species and suggested that they would be better grouped in a genus with more clearly defined morphological characteristics. The first works on the Pleurothallis phylogeny were published in 2001, supporting this hypothesis.
Therefore, in 2001 Pridgeon and Chase expanded the definition of this genus to include the roughly sixty species corresponding to the section Muscosae from Specklinia in addition to transferring all species previously classified in the subgenus Acuminatia and from the sections Acuminatae, Anathallis, and Margaritifera.
In 2006, Luer proposed the genus Panmorphia for these species because he felt that they would form a differentiated group alongside Anathallis and that this section would be better as a separate genus because they were morphologically very different from these.
The Brazilian species have not yet been thoroughly studied by Luer or Pridgeon & Chase, and many plants that must be members of this genus are still unknown, forgotten in Pleurothallis awaiting further investigation.
The distinctions between Anathallis and Panmorphia are still not clearly defined, and there are ongoing transfers of species from one genus to the other as well as species that were formerly assigned to the Pleurothallis genus but have since been identified and assigned to one of the two genera. Here, we divide the species based on Luer’s most recent work, though it should be noted that as our understanding of these species grows, more changes should be anticipated.
We will now discuss Anathallis in the strictest sense, which is the subgenus Acuminatia of Pleurothallis. Until a consensus is reached, the remaining species are categorized as Panmorphia here.

How to Care Anathallis Obovata?
It is a small, warm-to-cold-growing unifoliate epiphyte that can grow up to 9 cm tall and has erect, slender, 4-cm-long ramicauls that are surrounded by two to three tubular sheaths at the base and another below the middle. The single leaf is 5 cm long, including the 0.6 cm long petiole, apical, erect, coriaceous, elliptical to elliptical obovate, subacute to obtuse, and cuneate below into the petiolate base.
The South American bonnet orchid blooms from the short fascicle of a capillary, fractiflex, laxly three to four-flowered inflorescence with the flowers held close to the leaf base in the fall and winter. The flowers have an orange foot on the column and measure 0.3 cm in diameter.
Light: Anathallis obovata requires between 12000 and 18000 lux of illumination. The plants shouldn’t be exposed to direct sunlight in the afternoon; instead, the light should be diffused or filtered. Constantly strong airflow should be guaranteed.
Temperature: Summertime temperatures typically range from 27 to 29 °C during the day and 21 to 23 °C at night, with a daily amplitude of 6 to 8 ° C. Winter temperatures typically range from 25 to 26 °C during the day and 18 to 20 °C at night, with a daily amplitude of 6 to 8 ° C.
Humidity: South American bonnet orchids require year-round humidity levels of probably around 80%. The plant’s growth is stymied, and the leaves start to dry out and turn yellow in an environment with too little moisture. A room containing plants needs to be ventilated more frequently and for longer periods of time the higher the humidity, the more likely it is that the plants will rot and develop various types of fungal diseases. When the plants are growing and in leaf, proper air circulation is crucial.
Substrate: Anathallis obovata can be grown in tiny pots, baskets, or mounted on pieces of tree ferns with peat moss pillows around the roots, high humidity being ensured, and daily watering in the summer, though it might be necessary to water several times a day during the dry and hot periods.
Additionally, fir bark or finely chopped tree fern fibers are used as a very loose, quickly drying substrate when growing these plants in pots or hanging baskets. Additionally, perlite and other materials that release the substrate but frequently hold onto some of the moisture are frequently added to this mixture. Additionally, the addition of charcoal enhances the substrate’s permeability and offers protection from acidification.
Watering: During the period of intense growth from the end of the summer to the beginning of winter, Anathallis obovata should receive copious amounts of water. However, excellent drainage must be ensured to prevent the ground around the roots from becoming dry or soggy.
Fertilizer: While the South American bonnet orchid is actively growing, it should be fertilized once every two weeks with 1/4 to 1/2 of the recommended orchid fertilizer dose. You can use nitrogen-enriched fertilizer from spring to mid-summer, switching to phosphorus-enriched fertilizer in late summer and autumn.
Rest period: In the winter, Anathallis obovata require less water, particularly if they are grown in conditions of a short, dark day which are common in moderate latitudes. These plants shouldn’t, however, ever be completely dried out. Until new growths start to show and a more plentiful spring watering starts, fertilization should be decreased or stopped altogether.
