S ARO ODIA DIGHOTQMÁ. -¿arcodiae man^lnaitaft J. Ag.
próxima sed triallo magis gelatinoso, regJSfitti'iter dicho-
tomo, sumíais ramorum acutioribus et prolificationibus
númerosis saepe praesentibus distincta.

TJaaiLus planus, circiter 20 cm. al tus, flabellatim
dichotome ramosus circiter 0.5_r0.75 cm. latus, e margine
frondis prolificationes saepe numerosas gerens. Planta
obscurius brunneo-purpurea, carnoso-gelatinosa, exsicca-
tione chartae bene adhaerent.

India: Karachi, -J_ A. Murray (type in Kew Herb.) .
Manora near Karachi, Miss L. Here (Kew Herb.); A. B.
Kotwal (Herh . New York Bot. Garden) .

In the Kew Herbarium thre^ specimens are present;
two of these are richly provided with proliferations
along the margin of the thallus, one of which (the type
specimen) is figured on Plate V; the third specimen is
almost destitute of proliferations. A most proliferous
specimen is also found in the collection of the New York
Botanical Garden. All the specimens are tetrasporic,
the zonately divided tetrasporangia (Fig. 8) are develop-
ed in the cortical layer. The thallus increases "by the
fountain type method. A transverse section (Fig. 8 a)
shows at the periphery a cortical layer of small oblong
cells which passes over into a parenchymatic tissue of
roundish cells, the "bigger ones found innermost; in the
middle numerous filaments are woven together.

As mentioned above the plant is nearly related to
S. marginata J. Ag. and also to S^. cevlanlca: but it is
easily distinguished from these by the characters mention*
ed above and by the fact that only the Indian plant ad-
heres strongly to the paper.
