Pam Butler ... "Yet another tectorum in flower. I have had so many flowers this year and now have a lot of seed pods.
Does anyone know how long the seeds take to mature?"
Bob Reilly ... "Hi Pam: Mine seem to mature after 6 months or so here in Brisbane. However, the seed pods often do not change colour before opening, so I do put an open mesh bag over them."
Andrew Flower ... "Over here the tectorums mature in 8-12 months. (I say "tectorums" because thanks to Lotte H. many formerly labelled as "tectorum' have been given new names - the one that matures in 8 months actually keys out to T. oblivata)"

Habitat and range: Until now, this variety was only found in the arid areas of South Ecuador and in the inner Andean dry valleys of Peru at elevations of 700-2100 m. Various populations with minor differences in habit grow only in small areas. T. tectorum var. globosa grows almost exclusively as a lithophyte and, as portrayed, on steep, exposed rock walls.
These caulescent plants are easily distinguishable from those with compact growth. The rosettes of these plants are either completely stemless or they produce only a short, stocky stem with age. Most of the stemless forms are relatively small and hardly reach 25 cm in height when flowering. Several of these local forms can be grouped together despite some differences and described as a separate variety based on their virtually spherical rosettes (globosus = spherical).
The spherical rosettes always consist of white, very densely scaled leaves, similar to the rare form (HR 23029) that grows as an epiphyte at about 700 m together with T. disticha Kunth and T. cacticola L.B. Sm. in the dry forest near the Rio Chamaya in the Department of Cajamarca.
A form with a stemless rosette with shiny white scales (HR 17128) was also found to the south of the city Loja in a moderately moist climate on vertical, eroded, sunbaked conglomerate towers.
The most extremely scaled form, however, is only known from the Rio Utcubamba valley in the Department of Amazonas. There, it populates huge, smooth and almost vertical rock walls. Not only are the leaves dense with up to 5 mm long, needle-like scales but the inflorescence, which is somewhat distinct from other forms, has very short, stocky spikes (HR 2131, HR 2134 and HR 4179).
T. tectorum var. viridula L. Hrom., var. nov.
A varietate typica foliis et inflorescentiis viridulis, foliis perangustis et spicis floribusque minoribus differt.
Type: Peru, Amazonas: South of Chachapoyas, 2 100 m s. m., 27.07.1978, H. & L. Hromadnik HR 4181 (holo USM, iso WU).
Paratype: 1. c., 02.03.1997, K & L. Hromadnik HR 23054 (WU).
Plant growing as an epiphyte, stemless, flowering to 20 cm high; all parts except for petals somewhat greenish
Leaves narrower at the base than the other varieties, forming a globular rosette, to 14 cm long, very soft;
sheaths triangular-ovate, 10 mm wide at base, 20 mm long, thin, nerved, outside and inside densely lepidote;
blades distinct from sheath, 4 mm wide at base, greenish striate, tapering to filiform in the upper one third, scales long and as fine as a hair.
Scape exceeding the leaves, 2 mm in diameter;
scape-bracts sheaths densely imbricate and somewhat inflated, 15 mm long, 6 mm wide, oblong-elliptic, nerved, lepidote, pale greenish, blades filiform to 7 cm and equalling or exceeding the spikes.
Inflorescence densely digitate from 5-6 erect spikes, 3.5 cm long, 3 cm wide;
primary bracts: sheath thin, nerved, lepidote, outside flaky lepidote, the sheaths half as long as the spikes, but blades long filiform and mostly exceeding the top of the spikes; spikes subsessile, short lanceolate, complanate, 4-5-flowered, 2 sterile bracts at base; rhachis lepidote;
floral bracts 15 mm long, 8 mm wide, acuminate-ovate, thin, nerved, carinate, inside glabrous, outside densely lepidote with fine linear spreading scales.

stamens and pistil 11 mm long, filaments white, straight, filiform, anthers 3 mm long, 0.5 mm wide, subbasifixed, black, pollen beige;
ovary pale green, subglobose, 2.5 mm in diameter, stigma punctulate.
Habitat and range: Until now, this pretty, small plant was only known from the vicinity of the city Chachapoyas. It grows exclusively as an epiphyte at 1400-2100 m and in a much moister climate than otherwise expected for T. tectorum. Its companion plants were an exceptionally large-scaled, small form of T. humilis C. Presl and T. tovarensis Mez, both typical inhabitants of moist and cool altitudes.
T. tectorum var. viridula is another stemless local form, that differs in some characteristics from the aforementioned variety. It seems to be restricted to a relatively small area near the city Chachapoyas, Department of Amazonas.
These plants have almost thread-thin, greenish leaves and, therefore, fragile-looking rosettes. The scales are very finely hair-like. This plant merits the status of variety and is named for its uncommon greenish colouring. The characteristics of this variety, apart from the greenish colouring of the leaves and inflorescence, include: the very narrow leaf sheath and blade; the long scape bracts and the flaky lepidote primary bracts, that with their foliate blades exceed the top of the spikes; spikes only 4-5-flowered, floral bracts covered with long fine needle-like scales on the outside; flowers only 17 mm long, sepals only 10 mm long, but oval acuminate and 5 mm wide (not lanceolate), the posterior pair not free (connate for 2 mm), greenish white and hairy lepidote on the outside at the tip (not only scaled along the mid-vein).

primary bracts like the upper scape bracts, but only the apex adaxially lepidote, the lowest bearing a blade of 1 cm length, enfolding only the sterile part of the spikes;
spikes short stipitate, to 8 cm long, 12 mm wide, complanate, to 20-flowered, 2-3 sterile bracts towards the base;
rhachis densely lepidote, 4-angular, excavated, slightly flexuous, internodes 5-3 mm; floral bracts densely imbricate, 17 mm long, 11 mm wide, acute ovoid, nerved, carinate, lepidote only outside, rose.

ovary ovate, 3 mm long, 2 mm in diameter, yellowish green; stigma corresponds to type I of Brown & Gilmartin, lobes suberect.
Habitat and range: This beautiful, large form populates extended stands in the dry valleys of the Rio Negro, Rio Leon and Rio Jubones at an altitude between 1500 and 2400 m. It is too moist for xerophytic plants above and below this altitude.
Because of its spherical rosettes, this variety has the showiest appearance of the group. For a long time, it was known as the big 'Ecuador form', also recently called T. tectorum fo. gigantea by dealers. Because the name seems to be established and the plant is already known under this name, it should remain and is described here as such.
Because it forms several offsets after flowering, T. tectorum fo. gigantea often grows in large groups. One-meter wide, almost hemispherical cushions or dense, flattened extended mats can be formed on rocks and on precipitous rubble surfaces. On the stony slopes, the stands grow together with a large cushion form of T. disticha Kunth and with T. mima L.B. Sm.
The most outstanding characteristics of this compact and very short-stemmed form are the size of the rosette, the strong leaves, and the inflorescence with its extraordinary long, linear, strongly complanate and extended spikes, from which up to 20 flowers grow; the floral bracts and the pointed sepals are larger than in the other forms.
For more than 20 years, enormous quantities of this beautiful plant have been exported to Europe, sometimes even in big packages labeled 'dried plants for decoration'. Luckily, the populations in the few dry valleys in the provinces of Azuay and Loja in southern Ecuador, that are suitable as habitat for xerophytic plants, are so extensive that no serious damage has yet occurred.
