Holotype. Mexico. State of Chiapas, on road from Motozintla to Tapachula, 1800 m s.m., leg. K. & R. Ehlers 891303 (holotype, WU; isotypes, WU). Growing on pine trees with Tillandsia fuchsii Till, T. butzii Mez.
Habitat. Guatemala and Mexico near the common border. In Guatemala, the plant grows in humid forest areas, mostly on volcanic mountains.
Etymology: The name is taken from the Latin adjective, velutina, meaning velvety.
Additional material. Mexico. Chiapas, Motozintla, leg. K. & R. Ehlers EM 880707, 7.3.88. Guatemala. Depto. Guatemala, Antigua, San Lucas, Vulcan Bacaya 1200-2000 m, leg. Uwe Feldhoff & Jiirgen Mowinski, 1989.
Tillandsia velutina differs from T. brachycaulos Schlechtendal as follows:
Plant a more spreading rosette,
Leaves darker green, more densely pruinose lepidote on both sides, the indistinct sheaths castaneous.
Scape bracts densely pruinose. At anthesis, the interior leaves and primary bracts blush carmine in contrast to the cherry color of T. brachycaulos.
Scape is shorter,
Spikes are without sterile bracts, at the apex of the inflorescence several single flowers appear without primary bracts (in T. brachycaulos the apical spikes mostly are reduced to a single flower subtended by a primary bract).
The first flowers appear at apex and the last flowers bloom from the basal spikes (the reverse in T. brachycaulos).
Floral bracts and sepals are longer,
Petals are somewhat shorter.
Tillandsia velutina grows in damp forests, 1200-2200 m s.m. while T. brachycaulos normally grows from sea level to 1200 m (up to 1700 m) in dry areas.

Tillandsia velutina also differs from T. abdita L.B. Smith by its glabrous floral bracts and subglabrous sepals, which are connate for up to 14 mm for the adaxial pair.
Notes
This plant, for which I propose the name Tillandsia velutina, has been available for many years in nurseries and sold under various names such as T. abdita or T. brachycaulos var. multiflora. (T. brachycaulos var. multiflora is considered by many specialists to represent a natural hybrid of T. brachycaulos and T. caput-medusae.-H.E.L.)
There is a very nice color photo of it in Paul Isley's book TILLANDSIA (pages 28-29) and his description mentions "a velvety look and feel."
When we collected the plant in 1988 on our first trip to Chiapas, I studied the material and found that it differed in so many characters from Tillandsia brachycaulos that it should be considered a new species.
Tillandsia velutina R. Ehlers differs from T. brachycaulos Schlechtendal, by the stronger radiating rosette, the darker green leaves with indistinct, brown sheaths, with more dense and velvety scales on both sides. The stem bracts are also densely lepidote. During the peak blooming period, the floral bracts and primary bracts take on an intensive carmine red colour - as opposed to the cherry red colour of T. brachycaulos. The stem is shorter, nearly non-existent. There are no sterile bracts on the base of the spike, there are several individual flowers at the tip of the inflorescence which do not have a primary bract. (With T. brachycaulos, the top spikes are also usually reduced to a single flower, but this is surrounded by a primary bract). The first flowers appear at the tip of the inflorescence and the lowest spikes flower last. This is exactly the opposite with T. brachycaulos. The flower bracts are longer, the sepals are longer, the petals a little shorter with an elliptic blade.
The plant grows in moist forest areas, in higher locations up to 2200m while T. brachycaulos generally grows in lower areas and drier, hotter zones.
It differs from T. abdita L.B.Smith by its bare flower bracts, the nearly bare sepals whose rear ones are fused (connate) by up to 14 mm.
