Picture Pattern help

I have never worked from a picture pattern before. I've been writing it out round by round but am having trouble understanding some of it. It's a UK pattern so I've converted stitches to US. In round 12, 13, 14 the pattern shows a T with no cross. This is not in the pattern key so I'm guessing it's a hdc but am not sure. In rnd 14 I think there are clusters maybe trcl? Any help would be appreciated. I would really like to make this.
