Dr. John Reeder has drawn my attention to some errors I (Mary Barkworth) made in the treatment
of *Spartina* in FNA 25:

1) The generic treatment states that there are no lodicules in the genus.
Reeder and Singh (1967) reported that their investigations of *S.
patens, S.
pectinata,* and *S. spartinae* show that all three species have "truncate
vascularized lodicules, similar to those characteristic of eragrostoid-chloridoid
grasses".

2) Many of the chromosome counts that I listed for *Spartina* in FNA 25
are incorrect. The base number for the genus is correctly stated as being *x* =
10. Despite this, I listed several numbers that were multiples of 7. I
have listed correct counts below, together with their place of publication.
Some of the numbers listed were correct in FNA 25. I thought, however,
that presenting all the information in one place might be useful.

*Spartina anglica*: 2*n* = 122 (Marchant
1963); 122, 124 (Marchant
1968a)

*Spartina alterniflora*: 2*n* = 62
(Marchant 1963, 1968b).

*Spartina arundinacea*: 2*n* = 40 (Marchant
1968b).

*Spartina bakeri*: 2*n* = 40 (Marchant
1968b).

*Spartina cynosuroides*: 2*n* = 40 (Marchant
1968b).

*Spartina densiflora*: 2*n* = 60 (Gerish 1979,
as *S. foliosa* but probably *S. densiflora,* see Spicher
and Josselyn 1985).

*Spartina foliosa*: 2*n* = 60 (Reeder
1984).

*Spartina glabra*: 2*n* = 62 (Marchant
1963, 1968b).

*Spartina gracilis*: 2*n* = 40 (Marchant
1968b; Reeder
1977).

*Spartina maritima*: 2*n* = 60 (Marchant
1963).

*Spartina patens*: 2*n* = 40 (Marchant
1968b; Reeder
and Singh 1967).

*Spartina pectinata*: 2*n* = 40 (Marchant
1963, 1968b; Reeder 1977); 40 + 1
(Marchant 1963, 1968b); 80 (Reeder
1977).

*Spartina spartinae*: *n* = 20
(Gould 1958, Reeder and Singh 1967).

*Spartina* ×*townsendii:* 2*n* = 62
(Marchant 1963); 60+2 (Marchant
1968a).
