Plant : epiphytic.

Leaves : many, densely rosulate, forming an infundibuliform cavity, ligulate, rigid, totally green, attaining more than a meter.

Sheaths : elliptic, 30 cm long, 10 cm maximum width, densely lepidote at both sides.

Scape : 5 cm long, 2 cm diameter.

Scape bracts : narrowly ovate, much acuminate, 6 cm long, entire, yellowish.

Inflorescence : compound, multi-flowered, sub-capitate, 13 cm diameter, 9 cm long, forming a deep nest inside the leaves.

Primary bracts : narrowly ovate, very acuminate, 6 cm long, entire, thin, yellowish, finely nervate, whitish- lepidote to apex.

Branches : corymbose, about 10 flowers.

Peduncle : thick , the outer 2 cm long, the inner 1 cm long, considerably exceeding the bracts.

Floral bracts : lanceolate, very acuminate, apex spiny, 55 mm long, entire, thin ,greenish , finely nervate but never carinate, white- lepidote to apex, especially spiny, equaling the middle or exceeding the sepals.

Pedicels : 4 mm long, inconspicuous.

Flowers : 8 cm long.

Sepals : narrowly lanceolate, very acuminate and spinescent, 50 mm long, 6 to 7 mm wide, asymmetric, green, ecarinate, 10 mm connate at the base, white- lanate to apex .

Petals : spathulate, apiculate, 60 mm long, 15 mm connate at base, violet, open at anthesis.

Stamens : 50 mm long, complanate filaments, 15 to 20 mm adnate to petals.

Anthers : lanceolate, mucronate, 14 mm long, dorsifixed over the base.

Epigynous tube : 4 mm long.

Ovary : sub-ovate, 20 mm long, white.

Placenta : fixed near locule´s apex .

Ovules : apiculate.

 

Typus : Brazil, Bahia State, Una , Una- Canavieira Road, BA-001, in hygrophyle Forest, collected by Elton M.C. Leme, nº 445 , A .M. de Carvalho, L. A . Silva, J. Kent and R. Frasier, on the 8th January 1983 . Holotypus at Herbarium Bradeanum , HB .

 

Comments : This remarkable species does not fit in well in the subgenera key, in L.B. Smith & Downs' Monograph. The corolla is connate, the pedicels are very short and obscure, and it is very distinct from all the other compound inflorescence species, of any subgenera .It differs from all other species in the size of its flowers

which are 80 mm long, and its sepals which are 50 mm long, besides in other details .

 

Published : in Bradea, herbarium Bradeanum´s bulletin, volume IV, nº 1, 18th October 1983, Pg .1- 2 , Fig. 1. Pg. 5.

 

Complementary comments : Elton M.C. Leme in his book Canistropsis, Bromélias da Mata Atlântica, Pgs. 96 to 99, a Salamandra Edition, proposes a new Neoregelia subgenus, Protoregelia, causing extensive discussion over systematic positioning of this plant, complementary morphology details and living plant photos. Systematic position proposed:

Neoregelia L. B. Smith.

Subgenus Protoregelia W. Till & Leme.
