176 NOTES ON RUBI. 



terminal leaflets orbicular -ovate acuminate ivith a cordate 



base, basal leaflets very shortly stalked imbricate, panicle 



often leafy nearly to its top its axillary branches corymbose 



its prickles small unequal declining its setae aciculi and 



hairs many and unequal, sepals ovate-attenuate with a 



rather leaf-like point setose aciculate patent or adpressed 



to the fruit. 



Mr. Warren says that ty^Dical specimens of his R. dumetorum 



y pilosus ('J. of B.,' viii., 172) are in the Herb. Borr. from Fau*- 



cocks and the Slate Houses, Henfield. I presume that he refers to 



the specimens which I named B. fmco-ater in that herbarium. If 



so, his plant is what we have recently called R. Briggsii. But a 



specimen named by him v. pilosus for Mr. Bagnall appears much 



nearer to the R. BagnalUi, Blox. Of course this difference tends 



to confirm my idea that R. BagnalUi is not distinct from B. Briggsii. 



The true R. BagnalUi has much less and weaker armatures 



throughout, and its stem often seems nearly naked ; the panicle, in 



the specimens which I have seen, is narrow and few-flowered. 



Unfortunately they are long past the flowering state, and the 



colour and shape of the petals is therefore undeterminable. On 



the sjDecimens of R. Briggsii from the Slate Houses they are white, 



broadly ovate, very large and overlapping. The colour of the 



stamens and styles is also unknown to me. In a note appended to 



specimens sent to me, Mr. Bagnall remarks of B. Bagnalli: "I 



believe it to be a form of B. fusco-ater (evidently from a shady 



situation), much resembling R. Briggsii, Blox., which I refer also 



to B. fusco-ater as a variety or form." These plants may, i^erhaps, 



stand as varieties under B. emersistylus whether that is considered 



as distinct from or combined with B. fusco-ater. 



a. B. BagnalUi ; armature of the stem weak, prickles few short 

 slender, aciculi setae and hairs very short and incon- 

 spicuous, leaves rather thin wdth scattered hau'S on the 

 veins beneath nearly glabrous above. B. BagnalUi, Blox. 

 MS., in the " Set " issued in 1876 (name only.) 

 ft. B. Briggsii ; armature stronger, prickles more abundant 

 and stronger, aciculi setae and hairs more unequal and 

 more conspicuously passing into the prickles, leaves thick 

 hairy on the veins beneath with many scattered hairs 

 above. — B. Briggsii, Blox., in 'J. of B.,' vii., 33, t. 88. 

 a. In several places in Warwickshire ; Mr. J. Bagnall. 

 ft. Henfield, Sussex. Bickley Vale, Devon ; ^L'. T. B. Archer 

 Briggs. 

 It will be seen that the characters are only comparative, and there- 

 fore of very little value. 



14. R. PYRAMiDALis, Bah. — Mr. Briggs finds this abundantly 

 near Plymouth. Focke points out (p. 288) that there is an earlier 

 B.pyramidalis, published by Kaltenbach in his ' Flora des Aachener 

 Beckens ' (p. 275) in 1845, and he has given me good specimens of 

 it. He formerly called it It. vestitus, and circulated it to his friends
