of nearly a right angle, as in C. inermis. We have had no 

 opportunity of examining the two plants in the young state, 

 and are therefore not in a position to offer any opinion as to 

 their state in the early stages of development, bnt some ripe 

 berries of C. revoluta, for which we have to thank Mr. barnes, 

 of Bicton, have a form more like that which Prof. oudemans 

 attributes to C. inermis, that is to say, the apex is very slightly 

 if at all depressed, and it terminates in a well-marked project- 

 ing point, which is even more distinct in the hard inner shell 

 than on the exterior, though the elevated ridge spoken of by 

 Bi. oude mans is well marked on the onter fleshy, as also on 

 the inner woody, integnment. Again, the imprints of the vas- 

 cular bundies in Mr. barnes' specimens are certainly more than 

 two on each side and placed irregularly, as also are those which 

 ramify in the spongy layer within the woody shell. In colour 

 our specimens correspond with M. oudemans' account (cinnabar 

 red, not orange yellow), while in size our berries slightly exceed 

 those measured by the Amsterdam Professor. The fruit-bearing 

 leaf (carpophyll) of the Bicton plant agrees perfectly with the 

 description and figure given of^C. revoluta. Prom this we are 

 led to the conclusion that so far as the ripe ovules are concer- 

 ned, neither the shape of the outer fleshy integument nor of 

 the bony one in the interior, nor the distribution of the vas- 

 cular bundies offer such good distinctive characters as is stated 

 by our esteemed colleague. " 



Dr. carruthers heeft onlangs in het Herbarium van Lou- 

 reiro (zoo meldt mij alpb. de candolle) het exemplaar van 

 Cycas dat waarschijnlijk de C. inermis vertegenwoordigt, onder- 

 zocht, brengt het tot de soorten met gedoomde bladstelen, en 

 vergelijkt het met C. macrocarpa. Hieruit volgt genoegzaam dat 

 de plant van den Hortus te Amsterdam die ik vroeger voor lou- 

 reiro's soort hield, daartoe niet behoort, en dat waarschijnlijk 

 de diagnose van loureiro, wiens beschrijvingen niet altoos even 

 naauwkeurig zijn, op eene dwaling berust.
