Alcantarea regina

Alcantarea regina regina (Vellozo) Harms in Engler & Prantl, Nat. Pflanzenfam. ed. 2, 15a: 126. 1930.

Basionym: Tillandsia regina Vellozo, Fl. Flum. 136. 1829.
Vriesea regina (Vellozo) Beer, Bromel. 97.1857.
Etymology: regina, Latin for queen, in honor of D. Maria I of Portugal (1734-1816) who ruled the Portuguese Empire including Brazil from 1786-1816.

Still waiting for a description of this taxon which can only be obtained from field observations because of the mix-up in the past. See comment below by Leme in 1995.

The original concept of ‘geniculata’ was broadened by Smith & Downs (1977) to include a long list of synonyms. Consequently, there was a conceptual overlapping of taxa - as can be seen from the material cited by these authors - including A. regina which, according to these authors, is a sympatric species. Although A. regina is excluded from this analysis (this species is considered, here, to be restricted to the southern part of Rio de Janeiro state, and will be discussed in the next part of this series).

This plant is included here because of its inflorescence. Although the drawing is entirely incomprehensible, also there is no existing description, I am satisfied with it, and include it here.

Collected by Burchell in 1826 and introduced into cultivation by Linden in 1868. This is the giant of the genus. It is the type of Morren's subgenus Alcantarea, named after the Emperor of Brazil, characterised by its long narrow petal-blade and long stamens. V. gigantea Lemaire, is a form with shorter deflexed branches than in the type and more crowded flowers. V. gigantea Gaudich. Atlas, Bonite t. 70, from Santa Catherina, seems to be a starved variety of the same species with calyx only an inch long. Another very large species, 9-12 ft. high, with a very ample laxly bipinnate panicle, gathered by Roezl in New Granada in the province of Cauca, is mentioned in Haage and Schmidt's catalogue in 1872, under the name of T. gigantea.

Seeds spindle shaped, with very long, nicely crested divided top-mop of hair and relatively short basal mop of hair (Szidat in Bot. Archive I. [1922] 42);
Vriesea imperialis Morren. - Very magnificent stem forming herb, the largest of the family, from 2 to several metres high, growing on rocks; stem short or to 5 metres high, thick, crosswise-furrowed from leaf-scars; brood-base of young plants at the bottom of the stem;
leaf rosette very large,
leaves lineal, 0.5 to 1 metre long or longer.
Scape long, with large many flowered panicle made from a usually long rows of spike like racemes, ( pedicels short, thick),
bracts pink, red, greenish white or green;
Petals yellow, yellowish white, milky white (turning yellow later) or almost flesh-colored.

Approximately 7 species. From the Antilles (Haiti) comes apparently a not yet recollected A. panniculata (L.) Harms (based on Renealmia panniculata L.) in Plumier t. 237, which was impossibly treated by Mez under V. paniculata: in my opinion this is Tillandsia ringens Griseb. - a Vriesea of the subgenus Cylindrostachys. - Better known are the four Brazilian species often confused together from the mountains (on steep rockwalls) that are in the immediate vicinity to Rio de Janeiro, which one groups with Mez in the following manner,:

Discussion : (Translation by D Butcher) Alcantarea regina was treated for a long time as a doubtful species or of variable circumscription, not any preserved type specimen was seen to exist, nor were additional specimens collected in the area of the type locality, and because of the work and original illustration (Vellozo 1825, 1827) they are a little necessary. In the literature, there are many descriptions that include data of another species, A. glaziouana (Lem.) Leme, with a more northerly distribution in the state of Rio de Janeiro; these were adopted by several authors (e.g., Mez 1894, Smith & Downs 1977) and impeded the correct identification of A. regina for a long time.
In spite of the illustration of Vellozo (1827) being crude and incomplete, it was treated as the lecto-type for the genus Alcantarea (Grant, & Zijlstra 1998) and shows some characteristics of the species, with the apex of the leaf ensiform-acuminate to bent down, the different colouration of the sheath to the leaves and the proportion in the length of the floral bracts in relation to the sepals. As well as that, the suitable dimension in the original work (culmus supra orgyalis i.e., raised higher than a fathom), the type locality (Pharmacopolis i.e., Parati, RJ), the habitat (cautibus maritimus i.e., sea cliffs), the format of the appendages and the anthers, the flowering period and analysis of materials recently collected in the same habitat in the area of the type locality, indicate the need to propose a new synonymy, that includes Vriesea edmundoi Leme (= A. edmundoi).

Edmundo Pereira had begun the study of this species, which he had considered new. However, the accidental misplacement of exsiccatae stopped him making a decision and publishing his work.

Recently, we located the respective material deposited in Herbarium Bradeanum, in half the exsiccatae belonging to other species of the vegetable family. With that, it was possible to conclude the initial research for this nostalgic specialist and, as he could not finish it, to honor him with such an imposing new species.

V. edmundoi resembles V. imperialis Carriere, but differs in the smaller size, inflorescence predominantly green, primary bracts exceeds the sterile bases of the branches, and these show a smaller amount of sterile bra
