1918] Pennell,— A Plea for Aureolaria 135 
species with irregularly distributed red-purple markings within. 
Agalinis possesses usually smaller thinner corollas, rose-pink to pink 
(not purple as previously stated), normally within on the anterior 
side marked with two longitudinal yellow lines to the antero-lateral 
sinuses, between which lines are almost always red-purple spots. 
The few cases where either lines or spots are lost seem evidently due 
to suppression. Possible exception must be made of the aberrant 
A. linifolia, in which, while spotting is present, the lines are absent. 
This species is too isolated for the student to risk the assumption 
that lining was ever present. 
Second, anther-sacs. The anther-sacs of two of the three sub- 
genera into which I would divide Aureolaria bear strongly developed 
horn-like awns. These are almost always somewhat curved. In 
spite of Dr. Blake’s figure I can see little in common — except evo- 
lutionary origin — between these and the delicate semi-awning of 
Agalinis. In Agalinis there is every gradation between anthers 
rounded and anthers seemingly awned, but the latter state is ever 
an indeterminate attenuation and fusing, sometimes with slight 
hardening, of the lips of the orifice! A far stronger case for his 
argument would be the condition found in my proposed third sub- 
genus of Aureolaria, that which includes only the Mexican species, 
A. Greggii (S. Wats.).2 In this the anther-sacs are quite awnless. 
But in other essential features this is an Aureolaria, nor does it seem 
surprising — and certainly no evidence of close kinship — that a 
primitive awnless state should be retained both here and in Agalinis. 
A. Greggii stands in some other features apart from typical Aureolaria, 
as does the equally aberrant Agalinis linifolia from others of that 
genus. 
Third, capsule-shape. The distinction in this is constant, but the 
key-phrase for Agalinis should read “rounded with a mucro.” 
Fourth, seeds. In two subgenera of Aureolaria the seeds are 
1 Also the awning is always minute, I have seen no specimen showing this “precisely inter- 
d mediate” with Aureolaria. Agalinis peduncularis (Benth.) Pennell, comb. nov. (Gerardia 
peduncularis Benth. in Hook. Comp. Bot. Mag. 1: 209. 1835-6) seems a singularly unfortunate 
species to have.been selected as intermediate, inasmuch as in this the anther-sacs vary from 
awnless to minutely awned, or as I would express it, from “ acuminate to cuspidate.” The 
awns of Aureolaria grandiflora (Benth.) Pennell, comb. nov. (Gerardia grandiflora Benth., l. c. 
206), it is true, are short for that genus, but they are stout and slightly decurved, resembling 
minute horns.
