Miscellaneous botanical notes XXII

During a botanical tour in North Vietnam in 1961 Dr. Jeanplong collected a small Liliaceous plant which he could not check at the Paris Herbarium. Sending a duplicate to Dr. W. T. Stearn at the British Museum, the latter suggested it to belong to the tribe Johnsonieae to which Jeanplong agreed, classifying it as a new monotypic genus Halongia, next to the New South Wales Alania. My attention was drawn to it through the figures provided in the paper published recently by Jeanplong, which strongly reminded me of Thysanotus chinensis, a widely distributed member of an otherwise Australian genus, occurring from northern Australia with gaps to Thailand and China. Besides, a new Liliaceous genus from Indo-China would be quite unexpected.
