Stuck on a couple. Help appreciated
2d- a Jewish fast day commemorating the destruction of the 1st and 2nd temples in Jerusalem (6,3) T?S?A? B?B . Looks like it should be TISHAH BAV, but if so what is
18ac - a genus in the teasel family (8) ?C???O?A . I have Scabiosa for this, but if it's correct the last of the 3 letter word in 2d would be B not V. If Bav is correct then what is the answer to 18ac?
26d - a cluster of 5 stars in Taurus (5) H?A?S - I can find Hyades meeting this definition but not a 5 letter word. Suggestions?
