27. Homalobus strigosus (Coult. & Fish.) Rydb. This 

 resembles H. Palliseri in habit but differs in the pubescent pod 

 and longer calyx-lobes. Jones* claims that it is the same as 

 II. serotinus. It is true that the two resemble each other very 

 much in general appearance, but the calyx-lobes in H. strigosus 

 are almost twice as long and the leaves are cinereous on both 

 sides. Macbride regards it as a variety of H. serotinus.

28. Homalobus tenuifolius Nutt. The duplicate of Nut- 

 tail's type in the Torrey Herbarium is a small plant about 7 

 cm. high and bears two racemes, one with six flowers and the 

 other with a single pod. The calyx is 2 mm. long, including the 

 lobes, which are about 0.5 mm.; the corolla is about 4 mm. long, 

 and the pod, 14 mm. long and 3 mm. wide, is strigose; the leaflets 

 are narrowly linear-subulate. In the herbarium of the New 

 York Botanical Garden there is only one specimen in fruit like 

 it, Tweedy 259. The others are larger and would be referred to 

 H. decumbens if they were not so canescent and if the pods were 

 not straight. Gray, as already noted, thought that the species 

 was a depauperate form of H. campestris. Coulter and Nelson 

 seem to include it in that species, while Macbride united it with 



* Proc. Calif. Acad. II. 5: 668. 1895.
