256 LENTIBULACE^. [Utricnlaria. 



2. U. diantha, Roejn. and Schult. ; WigJd, /c. ^. 1569; Oliv. in Journ. 

 Linn. Sac. iii. 176 (noi of A. DC). Nearly allied to the last species, but a 

 smaller and more slender plant. Floating submerged stems seldom above 3 

 in. long ; the filiform leaves short, and little divided, with few small utiicles, 

 and in marshy places the leaves are linear-subulate and nearly entire. Scapes 

 or peduncles' filiform, 2 to 4 in. long, usually 1- or 2-flowered, rarely 3- 

 flowered. Flowers yellow, not above 3 lines across. Calyx-lobes equal, not 

 enlarged after flowering. Spur as long as the under lip, or longer. Stigma 

 small, sessile or nearly so. 



In small streams, Champion, WUford ; also Wright. In India, from the Peninsula to 

 the Archipelago, and northward to the Himalaya and S. China. 



3. U. coer'U.lea) Linn.; Oliv. in Journ. Linn. Sac. iii. 179 {not of A. DC). 

 A slender, simple, or rarely branched annual, usually 6 to 8 in. high, without 

 any leaves at the time of flowering. Scales verj^ few, ovate or lanceolate, 

 attached by their base. Flowers blue (or pui-ple ?), about 3 lines long, in a 

 loose raceme. Pedicels 3 to 3 lines long when in fruit, ascending or spread- 

 ing, (not turned down,) equal to or exceeding the length of the calyx. Calyx- 

 lobes ovate, near 3 lines long, and acute when in fniit, thin and membraneous, 

 enclosing the capsule. Corolla-spur conical ; the upper lip entire, obovate, 

 about the length of the calyx. 



In marshes, Champion; in a marsh on Victoria Peak, WiJford ; also Hance and Wright. 

 In Ceylon and the peninsula of India. The U. uUyivosa, Vahl, for which I had formerly 

 taken these specimens, is referred by OHver to the more common large-flowered JJ. reticulata, 

 Sni., which, however, does uot appear to have been found in Hongkong. 



4. U. bifida, Linn. ; Oliv. in Journ. Linn. Sac. iii. I S3. A little annual, 

 much resembling U. coerulea, but usually smaller and the flowers always yellow. 

 Fruiting pedicels recurved, 1 to near 3 lines long, and usually flat and dilated 

 under the calyx. Jjobes of the calyx when in fruit about 3 lines long and 

 very obtuse. — U. humilis, Wight, Ic. 1573, f. 3, and probably also of Vahl. 



Common in marshes, Champion and others. Frequent also in India from Ceylon and the 

 Peninsula to Malacca, and northwards to the Himalaya, S. China, and the Philippines. 



5. U. racemosa, TFall. ; Olio, in Journ. LAnn. Soc. iii. 186. A slender 

 but stift" annual, simple or seldom branched, usually 6 to 8 in. high, but some- 

 times above a foot, without any leaves at the time of flowering, turning black 

 in drying. Scales few, as well as the bracts under the pedicels, attached by 

 their centre, free and pointed both above and below. Flowers small, purple 

 (or blue ?) almost sessile, in little terminal heads or compact racemes, with 

 occasionally a few distant flowers lower down. Corolla 3 to 4 lines long, the 

 spur as long or rather longer than the lower lip. Capsules small, globular. — 

 Wight Ic. t. 1573, 1575, 1578, f. 3, and 1579. 



Common in marshes. Champion and others. Extends in India from Ceylon and the 

 Peninsula to the Archipelago, and northwards to Silhet and S. China. 



6. U. orbiculata, TFall.; Oliv.in Journ. Linn. Soc. Hi. ISl. An elegant 

 delicate species, 1 to 3 in. high. Leaves radical, persistent to the time of 

 flowering, orbicular or spathulate, not 1 line diameter, on a slender petiole 

 often 3 or 3 times as long. Scapes filiform. Bracts very minute, attached 

 by the base. Flowers 3 to 4, (lilac with a yellow palate,) very small, on 

 capillary pedicels. Spur very slender, above a line long, and longer tlian the
