Material examined: BRAZIL. Bahia: Jacobina, 4-VII-2003, H. Ribeiro & O. Ribeiro s.n. (HB54815); Cachoeira Véu da Noiva, 27-X - 1995, G. Jardim et al. 729 (CEPEC).

The only recordings of this species are referred to the municipal district of Jacobina in the state of Bahia, inhabiting shaded rocks in gallery forests.
Orthophytum navioides was described by Smith(1940), under the genus Cryptanthopsis. In 1955, the same author transferred the species to the genus Orthophytum, meanwhile without justifying such proposal (Smith 1955).
Orthophytum navioides resembles O. mucugense Wand. & Conceição for the similar habit, colouration and texture of leaves, bracts and sepals, but these species differ in the length of the leaf blades and the reproductive structures.

Butcher's note:
This changes the concept below where O. ophiuroides was included in the O. navioides description.

Habitat: the species occurs on vertical rocky faces, in general more than 30m high, at the edge of rivers and waterfalls, in shady and out of the way places, many times at points where water drainage occurs from the mountains. The substratum shallow and and principally full of entangled roots.
Distribution: species referred to previously as only from the type locality, Jacobina in the Chapada Diamantina, Bahia. In the present work new places of occurrence are added to the area, in the municipal district of Lencois, in river waterfalls that are in the mountains of the Parque Nacional da Chapada Diamantina.
Orthophytum navioides was described as Cryptanthopsis navioides by Smith (1939), based on material - Foster 90, coming from Jacobina, in Bahia. The holotype is deposited in G and the isotypes in SP, RB and US. In habit, fragile with linear leaves, narrow and long caudate and the presence of long stolons, are typical characteristics of this endemic species from Chapada Diamantina. However, except from vegetative parts, the morphology of the inflorescence and of the flowers are not particularly detailed in the original description. A very evident characteristic, not advised in the literature, is the red coloration of the center of the rosette at anthesis, making it quite ornamental. In the description in Smith & Downs (1979) the same illustrations of the original work and any additional material are maintained, showing the identity of this species, in general, is unknown. In the herbarium collections, other species of the genus are mistakenly identified under the name of O. navioides. Based on new collections obtained for the present work, a better recognition of the species was made possible, with the presentation of a more detailed description, in addition with more complete illustrations of the vegetative and reproductive structures of the plant.
As mentioned in the comment on O. mucugense, this species is similar to O. navioides, especially for the small size of the plant and leaves glabrous or glabrescent. Leme (2004a) links O. heleniceae with O. navioides, although it has just compared from cultivated material and the type material of the latter species. However, those two species are very different, being recognized easily by various characteristics, among them the larger size and width of the leaves of O. heleniceae, in addition to the margins conspicuous serrate and center of the rosette with two rings of very contrasting colors.
The species of Orthophytum with sessile inflorescences occurring in Chapada Diamantina are very attractive because of the colour of their bracts and leaves, in general, red at anthesis, having high ornamental potential and visual attraction to hummingbirds. The leaves, in spite of being spiny or serrate, are an ornamental characteristic of the species of the genus Orthophytum as a whole. Most of the species have leathery leaves, being covered with adpressed grey scales, especially in the xeric species, and being membranaceous and glabrous or with scarce indument in the species from humid areas.
The taxonomic problems involving Orthophytum is largely in the current shortage of good herbarium collections and of the little knowledge of the populations in situ. A great part of the characteristics of a species are lost in herbarium specimens, especially for the presence of congested inflorescences in the species without a scape. In that sense, attention should be given to the study of inflorescence patterns.
In addition the careful morphologic study accomplished through analysis of individuals in the field and of live collections, the use of new tools, such as anatomical data, cytogenetics and molecular studies will be fundamental for the infra-generic delimitation of Orthophytum.
