Flowers nocturnal, sessile, without the petals 6.5 mm in diameter, 36 mm long (petals stretched), not fragrant, contiguous with each other and the rachis (suberect); receptacle short, broadly obconic, 3 mm long, 5.6 mm in diameter, filled with laminar nectary tissue; sepals stiff-coriaceous to fleshy at the base, surface even or slightly nerved toward the apex and adaxially, symmetrical, obovate, rounded then acutish or acuminate, stiffly convex, 1.6 – 1.7 cm long, 0.8 – 0.9 cm wide, with hyaline margins, adaxial ones distinct from the abaxial one, adaxial ones bluntly carinate, evenly short connate for 3 mm, glabrous, lustrous, cream colored; petals not fleshy, 3.3 cm long, 0.6 – 0.7 cm wide, lingulate, rounded and slightly cucullate, with oblong-oblanceolate blade, highly connate and forming a tube of about 14 mm long, white, blade spreading. Stamens exserted caused by spreading of the petal-blades, all equal in length, 1.6 cm long, shorter than the pistil; filament largely conglutinate to the petals, adnate part flat and thin but the free part dilated, free part s-shaped, white, distally abruptly acuminate; anther dorsifixed at about one third from base, with strongly recurved upper half, 4 – 5 mm long, 1.2 mm wide, short bi-lobed at the base, obscurely apiculate, green, pollen cream colored. Pistil exceeding the stamens, 2.7 cm long; ovary subpyriform, 4.5 mm long, 3 mm wide, attenuate from near the base and slightly contracted into the style, largely superior, pale green; style elongate, 3 - 4 times longer than the ovary, slender, white; stigma simple erect (weekly conduplicate) and slightly wider than the style, densely papillose at the margins, greenish.	en	Gouda, Eric J.

184B878AE202F83AFF02CEB6E0B36475.taxon	discussion	Observations: — This new species resembles the much smaller Guzmania striata Smith (1959: 438). Obvious differences are the size, flowering 130 cm tall (vs. 70 cm), the much broader leaf blades (to 6 cm vs. 3 cm), the outer ones rounded and apiculate (vs. narrowly acuminate) and lax inflorescence with much longer spikes 9 – 12 cm long (vs. subdense inflorescence, spikes 5 cm long), for more detailed differences see Table 1. It also resembles Guzmania altsonii Smith (1930: 7) in some way, especially the sharply pungent peduncle bracts and inner leaves, which is rare in the genus. The later has more slender (fusiform) spikes 3.5 - 6 (- 8.2) cm long, ca 2 cm in diameter and 10 - 20 - flowered (vs. 9 - 12 cm long, 3 - 3.5 cm in diameter and c. 70 flowered).	en	Gouda, Eric J.

184B878AE202F83AFF02CEB6E0B36475.taxon	biology_ecology	Phenology: — the plant started to flower in culture in March and flowering could continue for several months (because of the many flowered spikes), it is not clear if this would be similar in the wild.	en	Gouda, Eric J.
