Aechmea orlandiana L. B. Smith, Arq. Bot. S. Paulo II. I: 55, pl. 69. 1941.
Desc. from S&D
Plant flowering 4 dm high, propagating by short ascending shoots.
Leaves about 20 in a dense funnel form rosette, to 3 dm long, marked beneath with broad purple brown spots or bands;
Sheaths large, very broadly elliptic, entire, dark purple beneath, covered on both sides with minute appressed brown scales;
Blades ligulate, broadly acute and apiculate, to 45 mm wide, obscurely punctulate-lepidote, serrate with straight spines 4 mm long.
Scape erect, slender, red, glabrous;
Scape-bracts erect and enfolding the scape, broadly elliptic, apiculate, serrulate toward apex, membranaceous, red, minutely white-flocculose, the lower shorter than the internodes, the upper imbricate.
Inflorescence very densely bipinnate, ovoid, 7 cm long, 5 cm in diameter;
Primary bracts like the scape-bracts, also serrulate, exceeding the spikes;
Spikes subsessile, dense, distichously 4-flowered, ca 3 cm long.
Floral bracts broadly ovate, acuminate, entire, exceeding the sepals, red, the margins free from the rhachis;
Flowers sessile, erect.
Sepals free, strongly asymmetric, suboblong, short-mucronulate, 11 mm long, nerved, glabrous;
Petals 2 cm long, blades erect, elliptic, broadly rounded, pale yellow except the white margins, bearing fimbriate scales at base;
Stamens included; pollen biporate;
Ovary slenderly ellipsoid, 6 mm long, epigynous tube short; placentae central; ovules obtuse.
Type. Foster 165 (holotype, GH), Itapemirim, Espirito Santo, Brazil, 7 Ju1 1939.
Distribution. Known from the type locality only: 17 Aug 1940, Foster 970 (GH, US).

Derek Butcher's comments
In 1998 I was discussing my problem with Moyna Prince of Miami who also had A. orlandiana ss. belloi which had not been grown from seed and could be traced back to Renato Bello of Brazil. Interestingly, Moyna had sent a leaf and inflorescence to Dr. Robert Read in Naples, Florida and I quote from some of the reply.
"There is an error in Lyman Smith's monograph where it says the spikes of Aechmea orlandiana are distichous whereas in fact they are polystichous. Now to your specimen where the primary bract has very minute serrulations if at all, and the primary bracts are shorter than the spikes, whereas the description for A. orlandiana says "primary bracts like the scape-bracts, also serrulate, exceeding the spikes". The monograph also says that floral bracts ...the margins free from the rhachis whereas in fact both A. orlandiana and your plant have the floral bracts attached to the rhachis but not like in the sub-genus Platyaechmea. Further, the Monograph states that sepals are strongly asymmetric...short-mucronulate whereas in my plant of this name the sepals are strongly asymmetric to my eye, sharply mucronate. Your plant on the other hand has sepals strongly asymmetric and inconspicuously mucronulate/apiculate. A. orlandiana has broadly rounded ovate scape and primary bracts which are strongly serrate and the primary bracts exceed the spikes, while your specimen has broadly lanceolate scape and primary bracts which are minutely serrulate. This means that a corrected description of Aechmea orlandiana is needed, but I guess the lack of bars on the leaves, the open inflorescence and other minutiae would indeed allow your plant the distinction of being a distinct variety if not a natural hybrid. As Lyman always said, "It happens all the time!"

There is a small reference to Aechmea orlandiana ss belloi in the BSIJ p66 (1989) but my next main step was to obtain a copy of Bradea 4 :34. 266-7 (1986) and Jason Grant helped me in this regard. No reference was made to the difference in teeth on the scape or primary bracts, nor to the polystichous spikes of ss. belloi and distichous spikes of ss. orlandiana, nor to the strongly asymmetric sepals of ss. orlandiana. No information was given as to other Bromeliads found in the vicinity to suggest possible hybridisation. Clearly, some botanist needs to correct the formal description of Aechmea orlandiana ss. orlandiana in view of Dr Robert Read's findings so that the relationships between it and ss belloi can be properly evaluated.
