# How to create trees with Qtree and math symbols

Hi I am trying to create a tree with two branches R<1 , R>1, which are labeled by math symbols (indices, \leq, ...). The second branch must be developed further. This almost works

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}\usepackage[novbox]{pdfsync}\usepackage{float}\usepackage{array}
\usepackage[T1]{fontenc}\usepackage{tikz,qtree}
\begin{document}
\Tree [.0 R_*$\leq$1  R_*>1 i_M$\leq$h_*
]
\end{document}


but actually I want the last branch i_M$\leq$h to be a child of R_*>1. I tried to group them

\Tree [.0 R_*$\leq$1  [.R_*>1 i_M$\leq$h_*]
]


but this ends up in fatal error . Thanks

\documentclass[12pt,a4paper]{article}
\Tree [.0 {$R_*\leq 1$} [.{$R_*>1$} {$i_M\leq h_*$} ]  ]
