NPA-PB-201602 | Figure 2(A) | One isolated empty sporangium with a vertical annulus (ca. 19 annulus cells), well visible stomium, and the annulus is interrupted by the remnant stalk at the base of the sporangium. |
NPA-PB-201603 | Figure 2(B) | One isolated sporangium with a vertical annulus (ca. 15 annulus cells), well visible stomium, and the annulus is interrupted by the remnant stalk at the base of the sporangium. |
NPA-PB-201727 | Figure 2(C) | One isolated empty sporangium with a vertical annulus (ca. 13 annulus cells), well visible stomium, and the annulus is interrupted by a remnant stalk (three rows) at the base of the sporangium. |
