ESTERN BOTANY NO. IS 



filiform leaves separates it from fimbriatum and acuminatum, both of 

 ^vhich have the thick and rigid bulb coats intermixed with thin ones, 

 but have the solid meshes which are so characteristic of acuminatum and 

 whose walls are raised forming pits in the coat, and which are very 

 minutely 'sinuous. But there is a difference in these markings. Tho-e 

 of acuminatum are triple, the meshes rounded or nearly round and deeply 

 pitted, so that they can be seen by the naked eye. Those of fimbriatum 

 are small and oblong, coarse walls apparently simple and little raised 

 but hard to make out, while the crests are fimbriate and very long. Both 

 these species have acuminate and very red flowers, fully half an inch 

 long. Tliose of lacunosum, the me'shes, are oblong, evidently pitted and 

 walls with a sharp ridge in the middle. The pods have entire crests 

 on the angles extending toward the center. The flowers are about half 

 the size of the others and mostly white or with pink stripes along the 

 middle and thin. There are other species with the same habit as tt;e 

 acuminntum group but the me'shes are serrate as in serratum, peninsulare, 

 etc. The color of the bulbs is 

 briatura.

Allium serratum Watson. Jepson is again in error on page 220 

 nf hi's ManiTal where he calls A. serratum A. peninsulare, and applies 

 the name serratum to A. amplectens. A casual reference to the Botany 

 of Californi-x pp. 148-9 and to Bot. King 487 t. 37 f. 4-5 shows conclu- 

 jvely th.^t Watson's type of A. serratum was the long and acuminate 

 flowered fonn which had been ref^iTed to A. acuminatum and which 

 JS plamlv A. pemnsulare of Lcramon. After the description Watson re- 

 fers to A. amplectens as probably a young state, but in this he was in 

 error. Aamp.ectens of Torrey was well described by Kellofrg, and this 

 inapprounate name amplectens was discarded by Watson who adopted 

 attenuifoluim in its place, but strict priority requires the retention of 

 amplectens. The p ants of this group are at once identifiable by the 



'\-^l .i-S'''''''^ f ^ ''''"^^ perianth, and seem to include A. Sanbornii 

 which differs m having the thick bulb coats with innumerable fine ver- 

 tical lines and minute vertically oblong meshes. A. Sanbornii may be 

 only an aberrant form of the other, for at times the zigzag markings 

 of amplcc ens may be wanting. One can see no reason for the absence of 

 these markings, but it is a fact just the feame 



Jepson proposes several new names for onions in his Manual, and of 

 these I cannot speak at present except to say that it is quite unlikely 

 that there can be so many undescribed species.
