KEY TO BRITISH RUBl. 



autograph is on the back of the title, and is appended to the 

 following note, in the same hand : — " Dono excellentissimi genero- 

 sissime Domini Lib : Baronis de Korst Sae. Cses. Russ. Majestatis 

 Ablegati Extraordinari fautoris et amici indulgentissimi possideo." 

 The principal subjects depicted are — Hyacinths (35), Fritil- 

 larias (30), Narcissus (8), Iris (39), Polyanthus (40), Anemones (47), 

 Tulips (54), Carnations (62), Lilies (8), Nigella (5), Oranges, &c. (9), 

 Aloes (47), Mesembryanthemums (24), Cactus (11), Sedums (13), 

 Stapelias (3), Euphorbias (10). In many cases there are more 

 forms than one on a page, so that the whole number of figures is 

 considerably over 500, Where all are so well executed, it is difficult 

 to single out any for special praise ; but the Tulips, Carnations, and 

 Polyanthuses are exceptionally beautiful. Nearly all the varieties 

 have French or German names attached. It appears from a note

AN ESSAY AT A KEY TO BRITISH RUBL 



By the Rev. W. Moyle Rogers, F.L.S. 



(Continued from p. 235.) 



Group 5. Egregu. — St. arcuate, arcuate-prostrate, or nearly 

 prostrate, bearing subequal prickles chiefly on the angles, and as a 

 rule (especially on its lower part) some, rarely many, scattered stalked 

 glands and acicles or small prickles, but no series of intermediate 

 acicles or prickles of all sizes, somewhat hairy or subglabrous. 

 Pan. with some, rarely many, stalked glands. In this group there 

 is a marked change in the usual direction of the fruiting sep. In 

 groups 2-4 they are as a rule distinctly reflexed. But here (as in 

 the 1st and the last three groups) the tendency is reversed ; in our 

 Egregii plants R. Banmngii (which I place provisionally as a var. 

 under U. mucronatus) being the only one in which the fruiting sep. 

 are distinctly reflexed, though they are sometimes partially so in 

 1?. mucronatus and li. Anglosaxonicus, and seem mostly so in li. 

 Bormanm (idtimfttefj). They are, however, reflexed in B. egregius 

 and li. Schlickumi (which have been thought probably British), as 

 in some of the other continental forms which Dr. Focke associates 

 with them. The name Egregii, Prof. Babington proposes adopting 

 from the Danes, to take the place of his Spectabiles, and answer to 

 Dr. iocke's Adenophori. In his paper on Rubi just published in 

 a Crerman Flora, Dr. Focke speaks of his Adenophori as "a group 



r natural 



but almost indispensable to a systematic coup d'ml," embracing the 

 glanduliferous species which differ from the Radius "by the 

 absence of a complete clothing of glandular bristles"; while they 

 are mostly weaker than the Villicaules (Silvatici), in which 



stalked glands only occur exceptionally. This corresponds exactly
