Uiholcos is his next genus and includes A. bisulcatus and Hav- 

 c'enianus. a well marked group, called Bisulcati by Gray which like all 

 of Rydberg's other segregations was first recognized by Gray or 

 Watson. As I have indicated this is rather too close to the Ocreati 

 for good separation. 



His next genus is Ctenophyllum and contains A. Grayi and pecti- 

 natus a well marked group but too close for separation from the 

 rest of the Podo-sclerocarpi, and already grouped by Gray under 

 the Pectinati. 



Cystium Steven is his next genus and is supposed to include 

 Gray's Diphysi. It follows Gray in everything even to including A. 

 platytropis which belongs in the Atrati or near there. He also 

 adds A. Boiseanus (arrectus var.) which belongs in the Reventi- 

 arrecti. 



Geoprumnon is another segregate to include Gray's Sarcocarpi, a 

 well marked group. 



Hamosus is another genus of Medic that he takes up. It corres- 

 ponds with the Leptocarpi and not the Hamosi of Medic. It contains 

 A. Nuttallianus, leptocarpus. Lindheimeri which form a good group. 

 But he also puts in it A. calycusus and var, which belong in the Ha- 

 mosi proper. And he puts A. atratus here also which belongs in 

 the Atrati. He places here A. atratiformis (straturensis) which 

 belongs in the Strigulosi. 



The next genus in order is not of Rydberg but Heller and id 

 called Hesperastragalus and includes the Didymocarpi of Gray but 

 neither Heller nor Rydberg sees that to it also belong Brazoensis, 

 Breweri and reflexus. 



Jonesiella is another Rydbergian genus to include the remark- 

 able A. asclepiadoides which belongs in the Preussii. 



Kentrophyta Nutt. is kept up and with the old limitations, but it 

 belongs in the Homalobi. 



Microphacos is one of his genera to include the Microlobi of 

 Gray, but is better placed in the Flexuosi, being only depauperate 

 forms of this group. 



Onix of Medic is taken up for A. Mulfordae, but this belongs in the 

 Hamosi. 



Homalobus is kept up and is a general hodge-podge of species. 

 Without naming the species which properly belong there and which 

 he puts there we find him blindly following Gray. A. collinus and 

 curvicarpus (Gibbsii) are here but belong in the Collini. A. deb- 

 ilis belongs in the Debiles. A. Fendleri and flexuosus belong in the 

 Flexuosi; A. grallator in the Bisulcati; A. Hallii in the Flexuosi; A. 

 macrocarpus (lonchocarpns) in the Lonchocarpi; A. miser in the 

 Inflati; A. stenophyllus in the Collini. 



The Phaca of Linnaeus is another wholly unintelligible mixup, 

 ns treated by Rydberg. As I have stated Phaca of Linnaeus belongs 

 to the Alpini. Rydberg puts A. ampullarius in it, but it belongs to 

 the Preussii, also A. artipes which is in the same group. He puts 

 A. artemisiarum (Beckwithii) here, which is also of the Preussi. A. 

 Bodini (debilis) he places here, but it belongs with the Inflati, the 

 same is true of A. cerussatus (triflorus), Cusickii, debilis, humilli- 

 mus, jejunus, leptaleus. ineptus (lentiginosus), microcystis (miser), 

 sabulonum, serpens, subcinereus, Wetherilli. He also puts A. Preus- 

 sii here but it belongs in the Preussii. He puts A. Reverchoni (loti- 

 florus) here but it belongs in the Lotiflori. He puts A. sesquiflorus 

 here but it belongs in the humistratus branch of the Homalobi. 



He creates the genus Phacopsis to include A. Pattersoni and 

 praelongus (Pattersoni var.) and adds A. scaphoides (arrectus var.) 

 which belongs in the Reventi-arrecti. The first two species belong in 

 the Preussii. 



He takes up Tium Medic and makes another general mixup. A. 

 alpinus (andinus) belongs in the Alpini. A. arrectus. atropubesceng 

 (arectus), eremiticus (arrectus var.) belong in the Reventi-arrecti.
