I am indebted to Professor Daubeny for the opportunity of 
giving a figure of the specimen in the Oxford Herbarium (for¬ 
merly Herb. Fielding), and to M. Spach for that of St. Hilaire 
from Brazil. Different in inflorescence as the two plants are, I 
have no hesitation in uniting them. The affinity is with C. setigera , 
Don, in which we find the same tendency to simple or compound 
spiculas. As in similar cases, the supplementary spiculse issue 
from a proliferous perigynium. 
300. C. tristacliya (Thunberg) ; spica brevi pallida, 
e spiculis 3-5 gracilibus oblongo-cylindricis, erectis, ter¬

exserte pedunculata; bracteis inferioribus vaginatis, 
subinde culmum sequantibus ; stigmatibus 3 ; perigyniis 
oblongo-ellipticis triquetris rostellatis ore emarginato, 
nervatis puberulis, subexcurvis stipitatis pallidis, squama

culus, basi foliatus, pars spicigera l-3g poll, longa. Folia 
culmea 1 lin. lata, radicalia 2 lin. lata, culmo multum lon¬

viores. Spicula 8-10 lin. longse, |-1 lin. latse; infima |-2|

apice modice excurvum. Achenium oblongo-ovale, triquetrum, 
apice aunulatum, basim styli bulbosum deciduum cingens. 
Anther a breves, filamentis latis clavatis acutis connatis ? in- 
structse. Stigmata 3, brevia. 
This delicate species, with the habit of the Digitatce, belongs to 
the group of the Sphceridiopliorce of Drejer, with annulate achenia, 
allied to C. leucoclilora, Bunge. When describing Dr. Morrow’s 
Japan Carices, at the request of Dr. Gray, I was led to separate 
it from C. tristachya, Thunberg, from the absence of all allusion 
to any pubescence in the perigynium of that species. But I 
suspect, from Schkuhr including it among species with pubescent 
perigynia, and from Wahlenberg’s description, that it is the plant 
of Thunberg. Whether the broad cuneate filaments are connate, 
as I supposed from Dr. Morrow’s specimens, I have had doubts 
since I have seen Dr. Hance’s specimens; for, though the filaments 
apparently adhere, as shown in the figure (u), I found one to 
become eventually detached, and it is probable that the pressure 
iu drying them gives the appearance of their being united. 
The specimens figured are,-— 
No. 1. Dr. Morrow’s specimens from Sitnada. 
No. 2. Mr. Hance’s specimens from Whampoa. 
801. q. manca (Boott); spica subelongata olivacea, e
