glance well separated. It occurs in Washington, Oregon, and Idaho. 

 T. montana, with its narrow and seemingly more erect leaflets and 

 stipules also has a recognizable aspect. It occurs from Idaho and 

 Montana to Colorado and Utah. The two ranges touch each other. 

 There are, however, specimens with the leaflet and stipule shape 

 and size intermediate between the two groups. Such ones are 

 Oregon, E. Hall 83 ; Idaho, Lolo Trail, Watson 76 ; Idaho, Falks 

 Store, Macbride 800 and 99. The last specimen is the type of 

 T. xylorhiza. The existence of these intermediates breaks down, it 

 seems, any specific lines. Aside from breadth of leaflet and stipule, 

 there are no other characters. The ranges are largely distinct, but 

 they touch. Hence, the two plants seem most truly classified as a 

 species and a variety. 



Thermopsis pinetorum Greene in its original description was 

 said to have "pods . . . pubescent or strigulose". Larisey (p. 252) 

 cites the specimen, Arizona, Chiricahua Mts., Blumer 1590. This 

 is in fruit. The pods are densely villous, except where the exocarp 

 has been worn off. Larisey keys this species (p. 245) under, "Pods 

 glabrate" and so describes it. Her treatment seems at variance 

 with the fruiting material seen and the original description. 



On page 252 Larisey publishes the name Thermopsis pauci- 

 flora Thornber ined. In the first place she does it in synonomy, 

 which makes the name invalid. In the second place the printing of 

 such rejected manuscript names causes a cluttering up of nomen- 

 clature. This practice is directly interdicted by the International 

 Botanical Rules (Rec. XXII, Cambridge, 1935). 



Baptisia mollis (Michx.) Nutt., Gen. N-. Am. PI. 1 : 281, 1818, 

 was not republished as new by De Candolle (Prodr. 2: 100, 1825) 

 who merely included Nuttall's species, attributed it to him, and 

 gave the reference. Larisey (p. 248) lists this non-existent B. mollis 

 (Michx.) DC. as a synonym of Thermopsis mollis (Michx.) M. A. 

 Curt., while lower down on the same page she lists B. mollis 

 (Michx.) Nutt. which is based on the same name-bringing syno- 

 nym Podalyria mollis Michx., as a synonym of T. jraxinifolia 

 (Nutt.) M. A. Curt. It is obvious that B. mollis cannot be a syno- 

 nym of T. jraxinifolia as it is the ultimate basis of T. mollis.
