326 EXPEDITION TO JAPAN. 



Carex excisa, Boott, (n. sp.) : spicis 4-5 rubro-purpureis oblongo-cylindraceis remotis 

 pedunculatis erectis, terminali mascula, foemineis (floriferis) gracilibus ]axifloris longe exserte 

 pedunculatis, infima radicali nunc basi composita ; bracteis subaphyllis ; stigmatibus 3 longis ; 

 perigyniis (juvenilissimis) ovalibus? erostratis emarginatis pubescentibus nervatis squama 

 oblonga obtusa emarginata cuspidata apice ciliata rubro-purpurea (nervo viridi) brevioribus. — 

 Near Yokobama, on the margin of ditches by the roadside. This is not unlikely the same as 

 the last species in an immature state ; and the suspicion, founded on their general resemblance, 

 is strengthened by a comparison of the racheola of 0. conica with the compound lower spike 

 occasionally met with in C. excisa. 



Carex lanceolata, Boott, (n. sp.): spicis 3 erectis pedunculatis purpureis, terminali mascula 

 abbreviata pauciflora, foemineis 2, superiori apicem masculse attingente, altera longiore paullo 

 remota brevi et exserte pedunculata ; bracteis aphyllis ; stigmatibus 3 longis ; perigyniis ovalibus 

 erostratis emarginatis plano-convexis scabris pallide viridibus nervatis basi glabris spongiosis 

 squama purpurea margine albo-hyalina lanceolata acuminata acuta vel hispido-cuspidata (nervo 

 viridi scabro) angustioribus fere dimidio brevioribus. — Hakodadi, in rocky places. Culms 7 or 

 8 inches long, weak, rather nodding, very scabrous, with 2 or 3 short and sheathing leaves at 

 the base ; the spike-bearing part 1\ to 2 inches long. Kadical leaves flat, half a line or a line 

 wide, slender, shorter than the culm. Sheaths 2 or 3 lines long, pale ferrugineous, bearing an 

 awn of a line or two in length. Peduncles scabrous, the lowest one 5-7 lines long. Male spike 

 4 or 5 lines long, half a line wide, 4-5 flowered, short-peduncled. Female spikes 5 or 6 lines 

 long, 2 lines wide, erect ; scales all similar ; those of the male spike pointless and ciliate ; of the 

 female spikes acuminate, acute, or with a hispid cusp. Perigynium over a line long, nerved 

 (the nerves of the same color,) scabrous, the spongy base pale and glabrous. Allied to C. 

 pediformis of Meyer, and scarcely distinct enough from C. pellucida of Turczaninow. It differs, 

 however, in its very scabrous culms, lanceolate and acute or acuminate scales nearly twice the 

 length of the perigynium, and in the nerved perigynium. From C. tristachya of Thunberg 

 (judging from Schkuhr's figure W W) it is distinguished by its short and few-flowered male 

 spike, the more remote female spikes, and the lanceolate scales. 



Carex Morrowi, Boott, (n. sp.) : spicis 5 remotis erectis, terminali mascula purpurea cylindrica 

 longiori, foemineis 4 oblongo-cylindricis laxifloris vaginatis, inferioribus exserte pedunculatis ; 

 bracteis subaphyllis ; stigmatibus 3 ; perigyniis ovalibus obtuse trigonis rostratis acute bifidis 

 pallidis divergentibus (rostro ferrugineo plus minus margine serrato deorsum recurvato) costato- 

 nervatis sparsim scabriusculis squama lanceolata acuminata acutissima purpurea basi pallida 

 brevioribus vel a?quilongis. — Simoda ? Culm 10 inches high, slender, smooth, obtusely angular, 

 clothed at the base with purple rudiments of leaves ; the spike-bearing portion 6 inches long. 

 Pvadical leaves glaucous, flat, rigid, striate, A\ lines wide, longer than the culm. Culm-leaves 

 all subulate and bract-like, sheathing. Lower bract longer than the peduncle, the others shorter 

 and more subulate. Peduncles 3-17 lines long, rather scabrous ; the sheaths 2-12 lines long, 

 pale purple. Male spike 16 lines long, a line wide, acute at both ends. Female spikes 4-9 

 lines long, 2^ lines wide, an inch or more apart ; the uppermost shorter and approximate to 

 the male spike ; scales all similar, the male ones larger. Perigynium nearly a line and a half 

 long, slightly scabrous under a lens ; the beak often serrulate on the margins, more strongly 

 nerved anteriorly. Achenium r % of a line long, elliptical, above obtusely triquetrous with 

 convex faces, below with flattish faces, punctulate, raised on an oblique stipe ; the base of the 

 style not thickened, deciduous. A fine species of the section Digitatce; distinguished from all 

 its allies by the divergent perigynia with a recurved and acutely bifid beak.
