have had also A. Oreganus, terminalis, and A. Cooperi (neglectus) 
which later he curiously places in Phaca. The allied species A. 
arrectus, conjunctus, ete. had not then been discovered. This group 
is evidently allied to the Sarcocarpi. 
His sixth section is Onobrychoides, the Onobrychoidei of DeCan- 
dolle. It contains A. adsurgens (nitidus) and Hypoglottis (agrestis) 
two very distinct and little related species but which are closer to- 
gether than to any other group, and which are probably nearer to 
the Chaetodontes. 
His seventh section should have been his first, the Reflexi and 
should not have been separated from the Didymocarpi to which its 
single species A. reflexus belongs along with A. Brazoensis. 
The eighth section is the Didymocarpi, and ninth the Micranthi 
showing that Gray had probably worked out the relationship cf these 
plants. : 
The tenth section (and following sections) takes up another 
wholly different set of species, of lower development for the most part. 
Section eleven is the Succumbentes, with the one species A. suc 
cumbens, a class by itself. This may have some relationship with the 
Galegiformes which he places next but I think is much nearer the 
Malaci. 
Next comes the Galegiformes two species which seem so radically 
distinct and yet cannot be separated or placed anywhere else to 
better advantage, A. Drummondii and racemosus. To this we now add 
A. scopulorum. This group is well placed next to the Ocreati, but 
Gray should have placed it in Phaca. The Galegiformes contains 
also A. cyrtoides (A. Gibbsii), Gray guessing from the flowers that 
it might belong here, but the guess was a poor one as it belongs 
elsewhere. 
The Ocreati, section eleven, contains three very diverse species. 
A. flavus is wholly 1-celled, as are the other species we now add to 
it. So is A. humistratus which belongs elsewhere. The other species 
A. Oreganus belongs with A. Canadensis, This group is very closely 
allied to the Bisulcati which Gray places rightly in the Phaca series. 
This group should also have contained A. gracilis and microlobus 
which he puts in section 13 and calls the Microlobi. 
The next section the Oroboidei is a hodge-podge of species, a 
catchall, and shows haste and little study. The first group in this 
section containing A. aboriginum, Robbinsii, oroboides (elegans) and 
alpinus (andinus) belongs to his Inflati under Phaca and forms a part 
of my Alpini, but Gray had to put them here because of the intrusion 
of the dorsal suture, which however is rot as great as that of the 
ventral. A. tener he also places here, but it belongs among the Lep- 
tocarpi. In another group in this section he puts A. Lindheimeri 
and distortus which belong with the Leptocarpi and Hamosi in spite 
of the septum of distortus being slight. He places here A. obcordatus 
which belongs with A. sparsiflorus, and A. glaber which belongs with 
the group Hamosi. 
The next class the fifteenth is the Lotiflori containing lotiflorus 
and villosus, two quite diverse species which have some similarity 
in flowers only. I think A. villosus is nearer the Sparsifiori to which I 
refer A. obcordatus and distortus, while A. lotiflorus which is both 
an Astragalus and Phaca according to the intrusion or absence of 
intrusion of dorsal suture belongs in a group with A. circumdatus, 
procumbens (accumbens) and Mohavensis, species not known then. 
Both these groups are related to the Inflati, Doubtless Gray 
placed these two species together because they could not be placed 
elsewhere and had a distant relationship, 
3 The last class of Astragalus proper, the sixteenth, is the Argo- 
phylli. This group Gray was also led to confuse by too much emphasis 
on the intrusion of the dorsal suture, and by too little knowledge of
