considered confluent stipules for their venation is not 

 what would be found under sueh circumslances but 

 precisely that of an ordinary leaf. » Lindley lays stress 

 upon modifications of ihe organs of végétation as being 

 suffîcient to divide into gênera species which do not essen- 

 tially diff'er in ihe organs of fructification... The structure 

 of ils flower, he says, is in every respect that of a Rose. 



Ledebour in 1850, Flora Altaica, t. 2, p. 2124, gives 

 an excellent description of ihe plant, nientioning ihe arran- 

 gement of the spines, their « decurrence » along the 

 branches and the allernate stripes of yellow and purplish 

 brown so produced. The stipules he describes as « binae 



connatae in. folium simplex, sessile apice bi-trifidum 



(iibi vera hujiis folii elucet natura\ 7iam si stipulae ad 

 apicem usqiie connatae siinl integrum, sin vero non plane 

 coalescunt, bilidum, denique si inter utramque stipulam 

 rudimentum foliaceum petioli foliive abortivi remanet, 

 trifîdum evadit), vel denique ovatum, toto ambitu argute 

 serratum, glabrum, glaiicum, etc. » Ledebour notes the 

 color of the petals and anthers, the setose interior of the 

 receptacular tube and the carpels « omnino glabra nec 

 latere exteriore, illo cui stylus adnatus est opposito, ut in 

 coeteris comata. » On account of thèse peculiarities Lede- 

 bour proposes to constitute a new genus Rhodopsis.

 1833, cent. IV, p. 20, t. 370, Ledebour gives a very good 

 colored figure of the plant showing the petals with their 

 spotted base, ihe globular fruit surmounted by the ascen- 

 ding sepals and the densely villose styles. He now des- 

 cribes the plant « foliis abortu nullis, stipulis connatis 

 foliiformibus glabris; aculeis slipularibus geminis ».
