This is Barolac, I can't recall the exact number but it's a variant of the 11100 pattern (just noticed John has already ID'd it as 11062 above). This one with the plain frosted finish looks decidedly post-war. For comparison here's a nice early 11100 vase with the taller rim from my collection:
http://glassgallery.yobunny.org.uk/displayimage.php?pos=-2446The mark is completely wrong - I agree it's probably an attempt at an R. Lalique mark, but it's a very poor one. Unfortunately there's a lot of Czech glass in circulation that has been damaged in this way - I really wonder why as Lalique's production has been very well documented.
Regarding your vase, it could be Inwald production, though the Barolac patterns were later made at Rosice and, more recently, Libochovice issued some designs, though the mould quality on the Libs pieces was markedly poor. Marcus Newhall has commented on the Libs versions on PK, and much of my Barolac collection has also been featured there.
Genuine Barolac marks are either acid stamp marks or are moulded, sometimes with an additional 'Made in Czecho-Slovakia' acid stamp. Some pieces destined for the French market carried a 'Tchécoslovaquie' acid stamp. On one occasion I saw a Barolac roses vase with a diamond point 'Barolac' mark, but I don't know if it was original. A great deal of Barolac, both early and more recent production, is unmarked.
