Striated Guzmania (Guzmania striata)
This epiphytic species is known exclusively from the type material which had been collected in 1956 from a tree on the banks of the Río Pastaza in the Pastaza Province of Ecuador.
The species has never been found since and is believed to be extinct.

Scaly Guzmania (Guzmania lepidota)
This epiphytic species is known only from the type collection that was found in 1876 in dense Andean forest at the base of the Pululahua volcano in the Pichincha Province of Evcuador.
The species has never been recorded since and is very likely extinct.
***
The Scaly Guzmania was superficially quite similar to the closely related Many-flowered Guzmania (Guzmania multiflora (André) André ex Mez) (see photo below), which is occurring in Colombia and Ecuador.

Poortman’s Guzmania (Guzmania poortmanii)
This epiphytic species was described in 1889; it is apparently only known from the type material that had been collected at what today is the city of Lauro Guerro in the Loja Province of Ecuador.
The species has never been found since and is apparently extinct.
***
The photo below shows a congeneric species also occurring in Ecuador, Weberbauer’s Guzmania (Guzmania weberbaueri Mez).

Erect-leaved Vriesea (Vriesea rectifolia)
The Erect-leaved Vriesia was described in 1984, it was found near the town of Correntes in the state of Pernambuco, eastern Brazil.
The species morphologically resembles Lubbers’ Vriesea (Vriesea lubbersii (Baker) E. Morren) from southeastern Brazil but differs from that species by its inflorescence with flowering branches and other characters.
The species was never found again in its type locality but was kept in a botanical garden for a while, where it flowered and died without leaving descendants.
Thus, the Erect-leaved Vriesea is now considered extinct. [1]
