and tropical regions, and many other species may be found 

 in the conservatories. But a short distance from the violet 

 family is the evening-primrose family; here may be found 

 a number of the evening primroses {Oenothera), with their 

 showy yellow flowers, noteworthy as the plants mainly 

 experimented with by Professors DeVries and MacDougal 

 in their studies on the origin of species. Along the brook, 

 not far from the loosestrife family, is the water-milfoil 

 family, represented by the Chilean water-milfoil or parrot's- 

 feather, forming a beautiful mass of feathery green on the 

 surface of the water. Returning now to the ridge, a little 

 beyond the violet family, we find the bed allotted to the 

 ginseng family; here are the Indian-root, from eastern 

 North America, and the heart-leaved aralia from Japan. 

 To this family also belongs the ginseng plant, the root of 

 which is so much prized by the Chinese as a medicine. 

 Down the slope from this group may be found two beds 

 given over to the carrot family, which includes many 

 economic plants, such as the carrot, parsnip, celery and 

 caraway; lovage, a common European plant, is shown, and 

 the rattlesnake-master, from the eastern United States; 

 the wild carrot and the golden meadow parsnip also belong 

 here. 



To the primrose family, located at the base of the ridge a 

 little beyond the carrot family, belong the primroses {Prim- 

 ula), many of which are natives of Europe; here we find the 

 common European primrose, the cowslip and others; the 

 moneywort, a native of Europe, but introduced into many 

 places in this country, sends its long creeping stem all over 

 the bed — this is sometimes known as creeping Charlie; the 

 fringed loosestrife, from North America, is also here, as is 

 the clethra-like loosestrife, from Japan, with its racemes of 

 white flowers. Between the two beds devoted to the carrot 

 family, and a little beyond, is the plumbago family, to 

 which belongs the common thrift of Europe; there are 

 several other thrifts here also, as well as the statices or 

 sea-lavenders, in several species. The bed allotted to the
