PAXTON'S FLOWER GARDEN. 



In this genus there is found to be so large a number of species, having such widely different 

 habits, that Botanists, at an early period of their acquaintance with them, were led to create many 

 supposed genera, the distinctions among which are now found to be unreal or unimportant. They, 

 however, in some cases, form good sectional divisions, of which a vacant page enables us to present 

 the following sketch, along with an enumeration of all the species known to us, and their more 

 important synonyms : —

c. Pseudobulbi tantum aut caules brevissimi ...... § 9. Bolbodium. 



d. Rhizomata tantum . § 10. Rhizobium. 



§ 1. APORUM. 



This consists of species with erect or prostrate stems; succulent equitant leaves, and 

 inconspicuous flowers. It includes the genera Macrostomium and Sarcostoma of Blume, and 

 Schismoceras of Presl., which seems to be Aporum Leonls. The following are the species : 



1. A. micranthum Griffith. 2. A. anceps Bindley. 3. A. Leonis Bl. 4. Dendrobium Sarcostoma Bl. 5. Macro- 

 stomium aloefolium Blumc. 6. A. sinuatum Bindley. 7. A. cuspidatum Wallich. 8. A. indivisum Blume. 9. A. 

 lobatum Id. 10. A. incrassatum Id. 11. A. Serra Bindley. 12. A. subteres Griffith. 



§ 2. STRONGYLE. 



Here are found all the Dendrobcs with tapering or awl-shaped leaves. The section is quite 

 analogous to the Cebolletes, among Oncids, as the last was to the equitant division of that genus. 

 Several of Blume' s Onychhtms must be referred to it. They are generally plants of no beauty. 



13. D. gracile Bindley. 14. D. tenellum Id. 15. D subulatum Id. 16. D. teretifolium B. Br. 17. D. acerosum 

 Bindley. 18. D. schoeninum Id. 19. D. teres Id. 20. D. crispatum Sivartz. 21. D. aciculare Bindley. 22. D. 

 junceum Id. 23. D. calamiforme Boddiges. 



§ 3. DESMOTRICHUM. 



With this section we enter upon the mass of the genus, with flat leaves, and more conspicuous 

 blossoms. They have erect stems, often more or less distended into pseudobulbs, and are remarkable 

 for the end of the lip being broken up into long tufted fringes, or in D. planibulbe, marginal threads. 



24. D. Scopa Bindley. 25. D. criniferum Id. 26. D. comatum Id. 27. D. angulatum Id. (There is another 

 species with this name in Eudendrobium.) 21!. D. Blumei Id. 99. D. planibulbe Id.
