UTRICULAR!^ OF THE MALAY PENINSULA. 



By 11. N. Ridley, M.A., F.L.B. 



The following Utricidarice were collected by myself in the Malay 

 Peninsula during the past six years. The list includes two now 

 species from the mountain districts of Kedah and the Ophir range, 

 where at some altitude these plants are particularly abundant. 



Utricularia jiexuosa Vahl, Knum. i. 198. Common in ditches 

 and ponds. The leaves are used in medicine by the JMalays, who 

 call it "Luraut Ekor Kuching" (Cat's-tail MossJ, or "Lumut Ekor 

 Kuniug" (Yellow-tail Moss). The flowers are bright orauge-yellow. 

 — Singapore : Garden Lake ; ditches at Ang Mo Kio ; Ohangi. 

 Malacca: rice-fields near Malacca; Selandau. Pahang: Kwala 

 Pahang. Lankawi: in paddy-fields (C'if/tis). Siam : Bangtaphau 

 {Dr. Keith). 



U. punctata Wall. C((t. 2121. Rare. Flowers pale blue. — Pahang : 

 CLenei Lake (IF. Fux). 



U. exoleta Br. I'ludr. 430. Flowers yellow. With U. Jiexuosa, 

 but much less common. — Singapore : Ang Mo Kio ; Garden Lake ; 

 ditches, Tanglin. 



U. Gi-ijfithii Wight, Icones, t. 1576. Li ditches and swampy 

 spots. Flowers of a beautiful bright purplish blue. — Singapore : 

 Local but abundant in the eastern part of the island ; Changi ; 

 Tampiuis ; Bedok ; Chua Chu Kang. Malacca : rice-fields, Bukit 

 Sabukor. A stunted form with a rather stouter stem, about 3 in. 

 tall, and a somewhat similar form, occurs also on Mount Ophir. 



U. bifoJa Linn. Spec. p. 26. Very common in ditches and 

 shallow sandy runnels. — Singapore : Bukifc Tmiah, &c. Pahang : 

 Kwala Pahang. Malacca: Ayer Panas, &c. Bindings: Lumut; 

 Penang {(Jurtis\). Lankawi {Curtisl). There seem to be two 

 forms of this : a small-flowered plain yellow one, and a form with 

 larger flowers, over J in. long, yellow, with a darker orange centre. 

 I found this on sandy heaths at Kwala Pahang, where the common 

 form also grew. 



The Utricularias of the Ilacemosce section are rather difficult to 

 separate. They inhabit wet sandy spots on heaths, usually where 

 water has stood, and it is very diilicult to get the leaves, as they 

 have usually perished by the time the flowers come out. What 

 adds to the difficulty is tliat as several species often grow together, 

 the foliage is mixed, and it is difficult to find which leaves belong to 

 which species. 



U. verticillata Benj. in Liniuia, xx. 312. U. hijida Wight, Ic. 

 1584, 2. A very delicate plant, with distinctly pedicelled pink 

 flowers. — Pahang: luvala Paiiaug. Lankawi: paddy-fields {Curds). 



U. racemosa Wall. (Jat. 1496. In all the plants which I have seen 

 the flowers are pure white. It frequents sandy spots where water has 

 lain. — Singapore : Very local, Ciiangi. Malacca : Bukit Sabukor. 

 Pahang: Kwala Pahang. Penang: Waterfall (C'»;t/.s). 



U. ophirensis, n. sp. Herba quam U. racemosa Wall, validior, 

 circiter b pollicaris. Folia anguste spathulata ^ pollicis longa
