TI. PLANTS WRIGHTIAN^. 27 



Pedro River (the same locality as that of No. 79) ; July : with young fruit. 

 (1340.) — These few specimens were gathered on the return journey, the past 

 summer. They resemble those of the collection of 1849, the unripe pods being an 

 inch and a half long ; except that one or two stunted plants have ripened pods 

 which are no larger than those of the preceding species ; but their seeds, &c. ex- 

 actly resemble those figured in Planta Wrir/htiancg. — The specimens gathered by 

 Dr. Gregg and Dr. Edwards near Monterey appear to belong to this species, but 

 they show no fruit.
