Nathaliella is a monotypic genus of flowering plants belonging to the family Scrophulariaceae. The only species is Nathaliella alaica. [1] It is also within Tribe Scrophularieae.

Contents

It is native to Kyrgyzstan, Uzbekistan and Xinjiang (in China). [1] It is found on sunny, stone filled slopes, at elevations of 1,500–1,600 metres (4,900–5,200 ft) above sea level. [2]

Description

It has thick roots. The caudex (plant stem) is covered in the remains of old leaves and white bristly hairs. It has a petiole (leaf stalk) that is about as twice as long as the leaf blade. The leaf blade is broadly ovate, [2] lanceolate or ovoid in shape. [3] They are about 1-1.5 cm wide and 0.5-1 cm long, with an entire (or smooth) margin. [2] It flowers in China in June. [2] The flowers are sessile (without stalk) or pedicellate (stalk of a flower), [3] which is short. [2] The Calyx is 4-5 mm long, [2] with 5 deeply lobes. [3] The corolla is about 1.5 cm long, and purple-red, [2] or pink-violet. [3] The limb is indistinctly 2 lipped. [3] The tube is narrowly cylindrical. [2] [3] The throat is slightly dilated. [2] It has 4 stamens, which are attached at the base of corolla tube. [2] [3] The filaments (stamen stalks) are filiform (thread-like) and glabrous (smooth). [2] The anthers are divergent. [3] In August, (in China) it produces a fruit or seed capsule, [2] which is ovoid, [2] [3] and glabrous. It is about 5-10 mm long and 3-4 mm wide. [2] Inside are numerous seeds. [3]

Taxonomy

The genus name of Nathaliella is in honour of Nathalie A. Desjatova-Shostenko (1889–1969), a Russian-French botanist noted for identifying at least 70 species of plants, many in the genus Thymus. [4] The Latin specific epithet of alaica refers to coming from the Alai Mountains between Kyrgyzstan and Tajikistan. [5]

Both species and genus were first described and published in Bot. Zhurn. S.S.S.R. Vol.17 on page 327 in 1932. [1] [6]

Culture

In 2011, a postage stamp series was issued in Uzbekistan with a set of illustrations of flowers, including Nathaliella alaicaB. Fedtsch. [7]
