MR. SCOTT Elliot's tropical African orchids. 197 



bus rotundatis, lobo medio oblongo obtuso, disco carinis quinis 

 instructo ; calcaie brevi couico prorsum verso ; columua brevi crassa. 



Hab. Open dry bare laterite, Samia, Kavirondo, Victoria 

 Nyauza, Jan. (dry interval between rains), 1894, No. 7081. 



Tiie slender stem, 14-17 in. long, is laxly flowered down to 

 about 3 in. above the base; tlie lower internodes are sheathed as in 

 L. pulchcUus. The lower lloweriug-bracts are ^ in. long, less above. 

 The small Howers are only 4^ lines in diameter. The dorsal sepal 

 is 3-nerved, 2 lines long by -| line broad ; the lateral ones are 

 4-nerved, and 2^ lines long by ■? line broad ; the petals 2^ by 1^ 

 lines. The rather narrow central lobo of the lip is 1^ lines by 1^; 

 the spur and the column are each | line long. 



Very near the Central African species L. pi/rophilus Echb. f., 

 but distinguished by its smaller flowers, more oblong sepals, dis- 

 tinctly ovate petals, and the smaller and narrower central lobe of 

 the lip. The colour of the flowers is also different. 



Lissochilus validus, sp. nov. Caule rufescente crassa, 

 bracteis obtusis brevibus, racemi elongati membranaceis oblongis 

 ovaria pedicellata baud a^quantibus ; fiorib us inter majores flavis, 

 sepalis concavis, dorsali cuneato-ligulato, lateralibu.s ligulatis basi 

 angustatis ; petalis oblongis, labello subpandurato basi fate saccato 

 ecafcarato, lobo terminali late oblongo crispato venis prominulis 

 divergentibus instructo, carinis ternis super sacci orificium gibbosis 

 et sub lobo terminali lamelliformiter cristatis; anthera bicoruicu- 

 lata. 



Hab. By marsh, Urundi, head of Lake Tanganyika, Sept. (end 

 of dry season), 1894, No. 8847. 



The thick stalk (the base of which is absent), with the raceme 

 (1 ft.), is 3 ft. long. The blunt membranous bracts are 1^ in. long 

 or less ; the two uppermost have a free margin ; the next below has 

 the margin united for half its length. A slender few-flowered 

 branch springs from the base of the raceme. The blunt floral 

 bracts reach f in. in length ; the stalks, with ovary, 1 in. The 

 sepals are 10 lines long, the dorsal 3 lines, the lateral 3^ lines broad. 

 The petals are 10 by 4^ lines. The lip is 1 in. long, and 7 lines 

 broad at the base ; the rounded end lobe is 4 lines long and as 

 broad ; the 3 median keels are raised into swollen rounded crests 

 above the entrance to the sac, and end in lamelliform crests with a 

 crispulate margin at the base of the central lobe. The column is 

 ^ in. long by 2 lines broad. 



Near L. atujolensis Keichb. f., but differs in its narrower ligulate 

 sepals and oblong petals. 



Var. MINOR. Bracteis lanccolatis, fioribus quam in typo minori- 

 bus, colore pallidioribus, petalis anguste oblongis. 



Hab. Jumotu Swamp, Kampala, Uganda, Feb. (between the 

 rains), 1894, No. 730i5. 



Tne upper part of the flowering-stalk only is present. 



Is distinguished from the type by its pointed lanceolate bracts 

 and smaller flowers, the sepals being scarcely 10 hnes long by 

 scarcely 3 broad, the petals 9 by 4 lines ; the lip I in. long, with a broad
