402 Transactions. — Botany. 



Hah. Auckland Islands. This interesting and, from a 

 systematic point of view, important species was collected by 

 Mr. F. E. Chapman, after whom I have much pleasure in 

 naming it. 



6. Deschavipsia tenella, sp. nov. 



Culms Sill, to more than a foot in length, tufted, much- 

 branched at the base, very slender. Leaves flaccid, setaceous, 

 striate, bright-green. Sin. long or less ; sheaths grooved and 

 produced into a long subulate scarious ligule broader at the 

 base than the blade of the leaf. 



Panicle 6in. long or less, rather effuse; the branches in 

 pairs, long, scabrid, capillary, subdivided twice or thrice, and 

 bearing few long-pedicelled minute spikelets. 



Spikelets very small, y^in. long or less, shining, two- 

 flowered ; outer glumes very unequal, membranous ; the lower 

 linear ; the upper linear-lanceolate, acute, faintly one-nerved, 

 and less tlian half the length of the spikelet ; flowering glume 

 oblong, membranous and hyaline, truncate at the apex v/ith 

 three short acute lobes, the middle lobe mucronate or shortly 

 awned, the awn decurrent as a ridge for half the length of the 

 glume ; palea bifid, vath two sub-median ciliate nerves ; rachis 

 and base of flowering glume clotlied with fine silk}' hairs ; 

 rachilla half the length of the upper flower, sparingly 

 pilose. 



Hah. Catlin's Eiver district, in moist rather open spots in 

 woods, up to 400ft. The plant from the Euahine and Tararua 

 Mountains, hitherto referred to Catahrosa antarctica, Hook, 

 fil., appears to be a form of this species, as I hear from Mr. N. 

 E. Brown, A.L.S., of the Kew Herbarium. 



7. Deschavipsia novcB-zelandue, sp. nov. 



Culms tufted, branched at the base, slender, ascending, 

 leafy below, -iin. to 12in. high. 



Leaves about one-third tlie length of the culm, almost 

 setaceous, striate and channelled above ; sheaths broad, mem- 

 branous, grooved, terminating in a long scarious subulate 

 sheath much broader than the blade of the leaf. 



Panicle about 2in. long, with rather few flowers; the 

 brandies in pairs or threes, short, giving off one or two pairs 

 of branchlets bearing few shortly pedicelled spikelets. 



Spikelets ^in. long, slender; outer glumes unequal (the 

 lower one-half, the upper two-thirds the length of the spikelet), 

 broadly lanceolate, sub-acute, membranous, one-nerved (tlie 

 upper sometimes three-nerved) ; flowering glume shortly ob- 

 long, membranous and hyaline, truncate, eroded at the apex 

 into 3 to 5 shallow acute or gently-rounded lobes, the middle 

 lobe occasionally shortly mucronate, nerves 3 to 5 very faint.
