SYNOPSIS OF THE SPECIES. 
(1) Spike single , not branched . 
I. C. dioi'ca. Spike simple; edges of the capsule finely serrated; barren 
and fertile florets on different plants. 
(2. C. Davallidna. Spike simple, dioecious ; fruit spear-shaped, triangular, 
ribbed, deflexed; its angles rough towards the summit. E.) 
3. C. pulica'ris. Spike simple, with barren and fertile florets ; fertile flowers 
uppermost; capsules diverging, reflexed, tapering at each end. 
4. <7. pauciflora . Spike simple, with barren and fertile florets; fertile florets 
about three, not closely set, expanding; barren florets generally ter¬ 
minal. 
(2) Spike compound; barren and fertile florets in each Spiket. 
[C. atrata.] 
5. C. stellula'ta. Spikets generally three or four, distant; capsules diverging, 
entire at the rim, acute. 
6. C. curia. Spikets about six, egg-shaped, rather distant, naked: scales 
egg-shaped, rather acute, shorter than the capsule. 
(7. C. donga ta. Spikets numerous, oblong, rather distant, naked; glumes 
ovate; tunic ovate, pointed, cloven, recurved, many-ribbed, longer 
than the glume. E. Bot. E.) 
8. C. ovaHis. Spikets about six, ovate, alternate, near together; scales 
spear-shaped, acute, as long as the capsule. 
9. C. remo'ta. Spikets axillary, solitary, distant, nearly sessile; floral leaf 
very long; capsules cloven at the end.* * 
10. C. axilla!ris. Spikets axillary, often three together, distant, sessile; 
floral leaf long ; capsules cloven at the end.* 
II. C. incur'va. Spike conical, composed of many spikets crowded together ; 
involucrum none; straw curved. 
12. C . arena'ria. Spike leafy, oblong, rather acute; spikets many, the 
upper ones barren, the lower fertile; straw curved. 
improved state of this Genus, but also to his private communications of specimens and 
observations, and to the trouble he has taking in looking over the references to figures, 
and pointing out such as he thought erroneous. (Sir J. E. Smith has since the publica¬ 
tion of our fourth Edition extended this Genus by several new species, which will be 
here found incorporated under the general arrangement of the Rev. Dr. Goodenough, 
who has likewise suggested an improvement of the generic character of Carex, by calling 
the permanent husk that invests the seed an arillus , a name which Sir J. E. Smith ob¬ 
serves, expresses its true nature much better than the hypothetical one of nectarium, the 
erroneous one of capsula, or even the analogical denomination of corolla . To the latter, 
however, it since appears, in a still more recent publication, has the learned President 
had recourse : so difficult is it even for the most scientific minds to assimilate their ideas 
of the mysterious analogies of nature. E.) 
* (The Rev. Dr. Goodenough, has since added,“ I believe all Carexes dispose of their 
seeds by the opening of the point of their capsule. This opening is observable in some 
very early, in others not till quite old. In the former, the capsule is described as opening ; 
in the latter, because it is not seen but in very advanced age, as closed.’ , Linn. Tr. 3.
