. The Gardeners' Chronicle and Agricultural Gazette . uM, Presl. Fronds erect, decurvpd at the points, ovate-acuminate, quitesmooth, tripinnatifid; primary divisions ovate-lanceolate; ulti-mate segments broadly linear, often elongated or subcaudate,drooping, enire; involucres sunk in the apex of the segments,orbicular, and anmewhat wedge-shaped lielow, the valves obtuse,entire; receptacles clavate, included; stipes and rachis greenand winged almost to the: base. One of the most beautiful Ferns of New it is very abundant. It also occurs iu LordAucklands Island, and in Java. The fronds oftenattain a foot and a half in height, with thtir stipes erect,and their branches gracefully decurved. The fiondsconsist, as it were, of several series of branchings orforkiDgs of the rachis and veins, these being throughout,and as well as the stipes, bordered with a green leafymargin on each side. In other words they are tripin-natifid, the first divisions ovate-lanceolate, tailed anddeflexed j their narrow sub-divisions are also tailed, and. these are again branched into short linear lobes. Eachof the ultimate segments has a single vein or rib passingalong its centre. The fructification is borne towards theapex of the ironds ; the sori situated at the apices ofthe ultimate lobes, in which the somewhat wedge-shapedbase of the involucre is sunk, its free portion beingrounded, entire, broader than the segment, and con-sisting of two valves, enclosing the short clavate recep-tacle. The fronds are of a deep olivaceous green, andpeculiarly smooth, the texture as in others of thisfamily being thin and transparent. It is a greenhouseevergreen species requiring abundance of atmosphericmoisture. T. M* DEGENERATION OF VARIETIES OF THEPEAR TREE.
