38 HALORAGE.E. 



R. amictum, Greene, is the Sierra Nevada variety of R. Menziesii, which Prof. 

 Greene thinks is confined to the Coast Region. All these prickly-fruited Ribes may be 

 considered varieties of Menzies' Gooseberry. 



CRASSULACEJE. 



Fleshy plants, with sepals, petals, stamens, and distinct carpels of the same number 

 (3-12), or the stamens twice as many: polypetalous or gamopetalous. Key to genera 

 and species, p. 122. 



T. Drummondii, T. & G. and T. Bolanderi, of Bay-Reg. Bot., may b-j considered 

 varieties of T. angustifolia. 



Low bog herbs, purplish or brownish, with radical leaves, bristly with gland-tipped 

 hairs which secrete a viscous fluid. Flowers in, usually, scorpioid racemes or spikes: 

 calyx 5-parted: petals and stamens 5: styles mostly 3, each 2-parted. The most 

 remarkable insectivorous plants belong to this order. Key to genera and species, p. 123. 



LYTHRACE^E. 



Our species, herbs with entire leaves. Flowers with tubular calyx, bearing the 

 petals and stamens on its throat, and rather closely inclosing the superior ovary: style 

 one. Key to genera and species, p. 124. 



AMMANTA. 

 A. coccinea, in Bay -Reg. Bot., is A. latifolia, arid Botala ramosior is A. humilis. 



LYTHRUM. 



Ij. Sanfordi, Greene. Erect stem, acutely 5-6 angled: petals 6, bright purple. 

 Much like 1L. Calif or nicum, of which it may be a variety. 



Ij. adsurgens, Greene. Branches 5- angled, 1-3 feet long, decumbent or assurgent, 

 slightly succulent: calyx 2^ lines long, 12-striate: petals pale purple. Similar to !L. 

 hyssopifolia, but perennial instead of annual, and much larger. 



HALORAGE^E. 



Aquatic herbs, with inconspicuous, often apetalous flowers, sessile in the axils of 

 leaves or bracts: calyx adherent to the ovary in the fertile ones, and its lobes then short 

 or obsolete. Flowers perfect, but apetalous, in Hippuris, and monoecious or perfect in 

 Myriophyllum. Key to genera and species, p. 124.
