372 ULiACEiE. . [Ojphiopoffon. 



In grassy places, Hance, Champion, Wright. On the adjacent continent, in the Philip- 

 pine Islands, and in Loochoo. After carefully comparing the original garden specimens of 

 0. spicatus with the smaller Chinese ones of 0. gracilis, I can find no definite distinction 

 even in the size of the flowers. I always find the style undivided in hoth. 



4. DIANELLA, Lara. 



Perianth of 6 equal spreading segments. Stamens 6, inserted at their base ; 

 filaments short, thickened under the erect anther. Ovary 3 -celled, with se- 

 veral ovules in each cell. Style filiform ; stigma entire. Fruit a berry. Seeds 

 flat. Embryo small. — Herbs, with a short rhizome, and stems leafy at least at 

 the base. Leaves long and narrow, parallel-veined. Flowers usually blue, 

 pendulous, in terminal panicles. 



A small tropical Asiatic or Australian genus, with one species from tropical America. 



1. D. ensifolia, Red.; Kunth, Ennm. v. 50 ; Bot. Mag. 1. 1404. Leaves 

 bifarious almost as in Iridece on the short base of the stem, erect, stiff, above 

 1 ft. long and 6 to 9 lines broad. Peduncle as long as the leaves, with 2 or 

 3 sheathing scales, and a terminal panicle of 2 to 4 in. ; the branches few and 

 short, simply racemose or forked. Perianth greenish-white or pale blue, the 

 segments lanceolate, 5 -nerved, about 5 lines long. Berry purple. — D. odorata, 

 Blume; Kunth, Enum. v. 51. 



Common in grassy places on the hillsides, Champion and others. In the Mauritius, Su- 

 matra, Java, the Philippines, Khasia, S. China, and Loochoo, and frequently cultivated in 

 India. The Chinese and Khasia specimens are usually almost or quite without the minute 

 serratures which are supposed to distinguish the leaves of the true D. ensifolia ; but occa- 

 sionally leaves may be found having them almost as marked as those of the Mauritius 

 specimens. 



5. THYSANOTUS, Br. 



Perianth of 6 spreading segments, 3 -nerved in the centre; the 3 outer with 

 thin flat edges, the 3 inner ones very delicate and rolled inwards in the bud 

 or ciliate on the edge. Stamens 6, inserted at their base ; filaments flat ; an- 

 thers erect, the 3 inner longer. Ovary 3-celled, with 2 ovules attached to the 

 centre of each cell. Capsule 3-valved". Seeds (when both ripen) 1 erect, the 

 other pendulous in each cell ; testa black, funiculus thick and fleshy. Embryo 

 curved. — Rhizome perennial, with fibrous or tuberous roots. Leaves almost 

 radical, usually narrow-linear or subulate. Flowers blue, in a raceme or panicle 

 sometimes contracted into an umbel on a leafless scape or peduncle. 



A genus entirely Australian, except the following species. 



1. T. chinensis, Benth.,n. sp. Rhizome short. Leaves radical, linear- 

 subulate, erect and stiff, 6 to 8 in. long. Scape as long, with a terminal um- 

 bel of 6 to 1 flowers. Bracts ovate or lanceolate, short and scale-like, with 

 white edges. Pedicels 4 to 6 lines long, recurved after flowering. Perianth- 

 segments near 4 lines long, the inner ones with broad very delicate involute 

 edges, but without the fringe of the Australian species. Capsule ovoid, often 

 with only 1 seed in each cell, but always occupying either the upper or the 

 lower half only. 



Hongkong, Hance. I describe this from a specimen gathered on the continent of S. 

 China by the Rev. Dr. Krone, and transmitted to me by Dr. Hance as having been also found 

 by himself in Hongkong. It too closely resembles the T. chrysantherus, F. Mull., from
