Plate 85, figures 10-18 Discussion. Drepanocladus aduncus var. kneiffii is distinguished by its nonfalcate leaves that frequently are laxly disposed along the stems. Otherwise, it is quite similar to the var. aduncus. I have not been able to discern an ecological distinction between our two varieties, but the morphological distinctions seem valid. The very non-Drepanocladus aspect can lead to misidentification, especially since our plants, like in the var. aduncus, sometimes lack the inflated alar differentiation in some leaves. Therefore, when hasty dissections are made it is possible to confuse the var. kneiffii with Leptodictyum riparium, which is more common in the West Indies. However, the much larger and more numerous alar cells in D. aduncus, whatever morphological variation it may assume, should distinguish it.
