acute base, and the ovary almost wholly inferior. It is commonly a 

 larger plant ; the petals are from one third to nearly half an inch in 

 length, their middle lobe occasionally laciniate-toothed. The pedicels 

 are usually about the length of the fruiting calyx. 



0. L. HETEROPHYLLA, Hook. & Am. sub Tellima. Scabro-hirta, 

 subpedalis; pedicellis brevissimis; calyce lato-campanulato minus hirto, 

 fructifero basi quasi truncato ; ovario libero stylisque glabris ; petalis 

 trilobis ; seminibus muriculatis. — California, common near the coast, 

 and northward. — The difference in the seeds (which are smaller and 

 rounder as well as muriculate) may assure us that the case of this and 

 the foregoing is not one of dimorphism. There appears also to be a 

 slight difference in the anthers. 



6. LiTHOPHRAGMA BoLANDERi, sp. nov. Major (1 -2-pedalis, fo- 

 liis ssepe 1-2-poll. latis),hirsutulo-scabrida; racemo elongato plurifloro; 

 pedicellis brevissimis seu calyce lato-campanulato (fructifero basi quasi 

 truncato) diraidio brevioribus ; ovario ima basi excepta libero ; petalis 

 nunc integerrimis nunc leviter trilobatis vel dente utrinque instructis ; 

 seminibus muricatulo-scabridis. — California, in a shady ravine, S. E. 

 of Monte Diablo (Dr. Brewer), and farther north in the Mendocino 

 district, H. N. Bolander. — The largest species : petals white, 3 or 4 

 lines long, more commonly all entire, sometimes all but one of the 

 flowers more or less toothed or even lobed. Styles, as in the next, 

 very short and glabrous. A slender form, in herb. Torrey, was col- 

 lected in the valley of the Sacramento by Dr. Stillman. 



7. LiTHOPHRAGMA Cymbalaria, Torr. & Gray {Saxifraga Cali- 

 fornica, Nutt. mss.). Exilis, ghibella ; caule scapiformi (6-14-polli- 



cari, foliis ^ - §-poll. diam.) 4-7-floro; pedicellis calyce campanulato- 

 cyathifbrmi (basi acuto) longioribus; ovario basi adnato; petalis spathu- 

 latis oblongisve integerrimis; seminibus muricatulo-scabridis. — Near 

 Santa Barbara, Nuttall, Parry, Brewer, in caiions. Cauline leaves 

 sometimes a pair and opposite or nearly so, sometimes alternate, occa- 

 sionally almost obsolete. Lobes of the calyx much shorter than the 

 tube except in Nuttall's very depauperate specimen. Petals, in good 

 flowers, 3 or 4 lines long.
