HAB. Frequent in the swamp-forests of the alluvial lands all over Burma, from Ava down to Tenasserim.-Fl. Jan.-March; Fr. Apr. June. 4. C. TETRAGONOCARPUM, Kurz in Journ. As. Soc. Beng. 1872. 306. HAB. Frequent in the swamp-forests of the alluvial lands of Pegu. -Fl. Febr. March; Fr. May, June.

5. C. OVALE, R. Br. in App. to Salt's Trav. in Abyss.; G. Don. in Linn. Trans. XV. 434.

HAB. Not unfrequent in the tropical and mixed forests of the Pegu Yomah; also in shrubbery etc. of Martaban east of Tounghoo.-Fl. March to May.

Possibly only a variety of the following species.

6. C. PILOSUM, Roxb. Fl. Ind. II. 231; G. Don in Linn. Trans. XV. 434.-(Poivrea pilosa, WA. Prod. I. 317 in adn. ; C. sp. Griff. Not. Dicot. 683 ?).

HAB. Pegu, Rangoon (Cleghorn); Tenasserim, from Moulmein (Falconer) to Mergui (Griff.); Ava, Kakhyen hills (J. Anderson).—Fl. Jan.

7. C. EXTENSUM, Roxb. Hort. Beng. 28 and Fl. Ind. II. 229; G. Don. in Linn. Trans. XV. 422 ?; Miq. Fl. Ind. Bat. I/1. 608. (C. rotundifolium, Roxb. Fl. Ind. II. 39, non Rich.; C. Horsfieldii, Miq. Fl. Ind. Bat. I/1. 609; C. platyphyllum, Heurck and Muell. Arg. Obs. bot. 1871. 243; C. formosum, Griff. Not. Dicot. 682).

HAB. Frequent in all leaf-shedding forests, especially along the larger rivers, all over Burma and the adjoining provinces. Fl. Jan.March; Fr. May.

8. C. SQUAMOSUM, Roxb. Fl. Ind. II. 231; Miq. Fl. Ind. Bat. I/1. 607; G. Don in Linn. Trans. XV. 438. (C. lepidotum, Presl Bot. Bemerk. 142; Walp. Ann. I. 290).

HAB. Frequent in the lower mixed and the open forests, especially the low ones, all over Pegu and from Martaban down to Tenasserim.—Fl. March, Apr. and Nov.; Fr. CS. and May, June.

A variety, or rather sport, from Prome (J. Anderson) with abnormal much bracted inflorescences, has all the scales developed into yellowish hairs, so as to appear hirsute all over. C. punctatum, Bl., differs not only by the very short obovate petals, but also in the inflorescence, shape of leaves, and the smaller fruits.

9. C. CHINENSE, Roxb. Fl. Ind. II. 230; G. Don. in Linn. Trans. XV. 432? (C. ternatum, Wall. Cat. 4002; C. Griffithii, Heurck and Muell. Arg. Obs. bot. 231).

HAB. Not unfrequent in the tropical forests of the Martaban hills, east of Tounghoo, up 3000 ft. elevation; Chittagong.-Fr. March, Apr. Don's C. Chinense is unknown to me and may possibly be the same as C. squamosum, Roxb., but the petals are apparently different.

10. C. DASYSTACHYUM, Kurz in Journ. As. Soc. Beng. 1874. 187. HAB. Not unfrequent in the tropical forests, especially along choungs, along the eastern slopes of the Pegu Yomah and of Martaban.-Fl. March, Apr.

12. C. QUADRANGULARE, Kurz in Journ. As. Soc. Beng. 1874. 188. HAB. Tenasserim (Helf. 2181).-Fl. Apr., May.

Judging from the description only, I do not think that this species may be compared with C. stelligerum of Presl.

Var. a. GENUINA, ovary and style villous; fruits and the beak more or less pubescent.

Var. B. PHILLYREÆFOLIA, (4. phillyrexfolia, Heurck and Muell. Arg. Obs. Bot. 209), ovary and style minutely appressed-pubescent; fruits and beak glabrous or nearly so.

HAB. Var. a. frequent in the mixed (especially the upper ones) and also in tropical forests, from Chittagong and Martaban down to Tenasserim, up to 3000 ft. elevation; var. B. restricted to the alluvial plains of Ava, Prome, and Pegu, chiefly in the swamp-forests.-Fl. Febr., March; Fr. Apr., May.

This tree is remarkable by the bark, which consists of herbaceous green tubercles covered with a smooth grey epidermis which is easily scraped off. By this mark the tree can be recognised from all others in Burma, but in the plains (the var. B.) the bark becomes white marmorate and conchoid (as in Emblica officinalis). I should certainly have specifically separated this swamp variety had I not met with trees that bore both kinds of bark.

Var. a. ROXBURGHII, leaves ovate-oblong to ovate-lanceolate, the larger ones 5-6 in. long, firmly chartaceous, more or less rusty or tawny pubescent beneath.

Wight and Arnott state that C. nutans with short stamens does not occur in Hindustan, but all the specimens which I have seen from there belong to C. nutans, none to C. floribunda, Lamk. (Getonia nutans, Roxb. Corom. Pl. I. 61. t. 87 ?).
