30 ENGLISH BOTANY. 



from C. lutetiana and C. alpina, or believe it to be a hybrid 

 between the two. This plant is 1 foot to 18 inches high, sub- 

 glabrous, and with the general habit of C. lutetiana, but with the 

 long-stalked broadly-ovate and abruptly-acuminate strongly den- 

 tate-serrate leaves of C. alpina ; like the latter it has bracts at the 

 base of the pedicels and the petals narrowed at the base. The 

 fruit is subglobular-ovoid, and is said by M. Doll to be always 

 sterile, an observation which I have not had an opportunity of 

 verifying : this circumstance has been urged in support of its hybrid 

 origin ; but against this is the fact that it often grows in places 

 where the other two plants are not found in company. Charac- 

 teristic specimens have been collected in Cheshire by Mr. G. E. 

 Hunt ; also near Loch Lomond by the late Mr. W. Gourlie ; and 

 by myself in Collinton Woods, near Edinburgh. On the whole I 

 incline to the views of those who consider it a very luxuriant form 

 of C. alpina. Examples of C. lutetiana with the leaves more dentate 

 than usual, and inclining to cordate at the base, arc very often 

 labelled C. intermedia by British botanists. 



Alpine Enchanter' 's-Nightshade. 



French, Gircee des Alpes. German, Geberys Ilexenkraiii. 



Sub-Okder II.— HAL011AGEJ3. 



Ovary 1- to 4-celled, with a single ovule in each cell. Seeds 

 albuminous. Leaves whorled, opposite or alternate, entire, toothed 

 or pectinate. Petals generally small, frequently absent. 



GENUS V— MYRIOPHYLLUM. IAam. 



Elowcrs monoecious or perfect. Calyx 4-partite in the male 

 flowers : adhering to the ovary and 4-toothcd in the female and 

 perfect ones. Petals 4, boat-shaped, caducous in the male flowers : 

 inconspicuous or absent in the female. Stamens 8, 4, or G. Ovary 

 4-celled ; stigmas oblong, recurved, papillose within. Fruit of 4 

 (or by abortion 2) indehiscent achenes enclosed in the adherent 

 tube of the calyx, at length separating from each other. 



Aquatic herbs with verticillate (more rarely opposite or alter- 

 nate) pectinate leaves, and terminal spikes of small sessile flowers 

 in the axils of pectinate, toothed, or entire bracts ; the part of the 

 stem which bears the male flowers usually rising out of the water 

 until the pollen is shed. 



The name of this genus comes from the Greek words /ii^inc (myrios), a myriad, and 

 «v\\»r (phyllon), a leaf j in reference to the numerous divisions of the leaves.
