T. H. BUFFHAM ON BONNEMAISONIA HAMIFERA. 181 



M. Hariot refers (loc. cit.) to a specimen of a Bonnemaisonia 

 from California, sent by Prof. Farlow, of Harvard University, 

 in 1887. This plant was doubtfully referred by M. Hariot to 

 B. hamifera. This specimen is in the possession of Dr. Bornet, 

 who kindly lent me it, and I am therefore able to offer a figure 

 of it (Fig. 8). Prof. Farlow marked this B. asparagoides ? Near 

 the base it bears two or three slender branches with hooked 

 extremities, which certainly seem analogous to those of the 

 typical B. hamifera. I have searched the herbaria at Kew and 

 the British Museum for any specimens of Bonnemaisonia bear- 

 ing hamose branches, with the result that I found none at Kew 

 and only one plant at the Museum. This is almost exactly like 

 two of the present fig. joined together near the base. On it 

 also there are two or three hooked branches precisely similar 

 to those in our fig. I have compared a small portion of this 

 specimen with the preparation of Farlow's made by Dr. Bornet, 

 and have no hesitation in concluding that they are one and 

 the same species. The following remarks are equally applicable 

 to the two specimens. 



The branches (pinna?) are in one plane, generally of linear 

 form. These are almost regularly pectinate, the ramuli 

 (pinnulae) alternating with a cystocarp or procarp (occasion- 

 ally two, as in Fig. 9), which are opposite to the ramuli. These 

 ramuli are short, thorn-like in form, and taper quickly, not 

 mucronate, and are devoid of spines ; the cortical cells near the 

 point being 15-20 fx in diam. (Fig. 10). No antheridia have 

 been seen. 



The British Museum specimen was received there in Dickie's 

 herbarium in 1884. It appears to have been contained in a 

 bundle of plants labelled " N. America." This specimen was 

 marked by Dickie 



Ptilota Calif omica filicina? N". America, 

 but bears neither the date nor the collector's name. There 

 can be little doubt that this was from California. Mr. Gr 

 Murray had placed it with other specimens of Bonnemaisonia. 



Here are its characters : —
