The distinction between Chondrophycus patentirameus and C. paniculatus (Ceramiales, Rhodophyta)

The red algae Chondrophycus patentirameus (Montagne) Nam (‘patentiramea’) and L. paniculata (C. Agardh) J. Agardh were investigated on the basis of type material and recent collections. Both species show the following features: (i) production of two vegetative pericentral cells from each axial segment; (ii) absence of secondary pit connections between cortical cells; (iii) lack of projecting cortical cells near the apex; (iv) absence of lenticular thickenings in the walls of medullary cells; and (v) perpendicular arrangement of tetrasporangia, each of which is produced from the second pericentral cell in each fertile segment with no additional tetrasporangial pericentral cells. However, C. patentirameus has a stoloniferous holdfast, divaricate branching (with branches arising at angles up to 90°) and non-palisade-like superficial cortical cells, whereas L. paniculata has a discoid holdfast, non-divaricate branching and a palisade-like cortical layer. From this study it is concluded that C. patentirameus (here lectotypified) is distinct from L. paniculata. The latter species is here transferred to the genus Chondrophycus (Tokida & Saito) Garbary & T. Harper as follows: Chondrophycus paniculatus (C. Agardh) G. Furnari.

The naming and typification of the breadfruit, Artocarpus altilis, and breadnut, A. camansi (Moraceae)

Abstract: The historical background and typification of the widely distributed and highly appreciated breadfruit tree, Artocarpus altilis (≡ Sitodium altile; Moraceae), and breadnut, A. camansi, is discussed. Sitodium altile is lectotypified selecting a watercolour painting by Sydney Parkinson made in Tahiti in 1769, during James Cooks first voyage around the world (1768–1771) in HMS Endeavour, and preserved at the Natural History Museum of London. A specimen from E. D. Merrills “illustrative specimens” of Blancos Philippine plants in the United States National Herbarium is designated as the neotype for A. camansi. Citation: Ferrer-Gallego P.

Typification of the Indo-Australasian Malay Banyan Ficus microcarpa L. f. (Moraceae)

The name Ficus microcarpa L. f. (Moraceae) is lectotypified using original material preserved in the Linnaean collection at LINN.

Typification of the African endemic plant Ottelia exserta (Hydrocharitaceae)

SummaryThe typification of the African endemic plant Ottelia exserta (Ridl.) Dandy (≡ Boottia exserta Ridl., Hydrocharitaceae) is discussed. Based on the protologue and consultation of original material, a specimen preserved in the herbarium at the Royal Botanic Gardens, Kew is designated as the lectotype.
