THAI FOREST BULLETIN (BOTANY) 36
This species has the general appearance, ligule and hilum of Arundinella, but the spikelets of Danthoniopsis. It was further distinguished by the remarkable one-celled hairs on the palea of the upper floret. This character has never been found in any of the genera in theArundinelleae (Bor, 1955).
Bor (1955) reported that most parts of the spikelets of this species, from a rather dry habitat in Bombay, were almost coriaceous.
The specimens examined from Thailand have been found to be smaller, have more compact panicles, and are less hairy on the glumes.
Uses.— Grazing (Bor, 1960).
Typification notes.— When Muller (1856) described Danthonia griffithiana he cited the specimen Griffith legit, collected from India Orientalis, Khasiya, as the type specimen, but he did not mention where it was kept. According to Stafleu & Cowan (1981), the main herbarium of Karl Muller is in B. There are two Griffith specimens in B, one of which is labelled Griffith 36 (B-10–0240400, from Röpert, 2000) and one of which has no number (B-10-0240395, from Röpert, 2000). Both are also labelled “Danthonia griffithiana n.sp.” in the same hand, possibly Muller’s. In 1938, Bor transferred this species to Arundinella and stated that the type herbarium sheet of D. griffithiana Mull. Hal., which was made available to him, was deposited in B. In 1955, he finally transferred it to Jansenella, as J. griffithiana (Mull.Hal.) Bor. In 1957, Conert published a monograph of Arundinelleae and stated that Griffith 36 in B was the holotype of J. griffithiana. As there are at least two original specimens neither of these two specimens can be a holotype. However, as Bor stated the type was in Berlin, one of these two specimens must be designated as a lectotype even if further material were to be found in another herbarium. It would appear that the unnumbered Griffith specimen (B-10–0240395) was borrowed by Bor in Kew and which he presumed to be the type. Unfortunately, Conert’s incorrect citation of the other specimen, Griffith 36 (B-10–0240400), as a holotype did have the effect of establishing that specimen as the lectotype.
When Thwaites (1864) published Arundinella avenacea Munro ex Thw., he cited a specimen of Thwaites CP 3471 from Ceylon but did not mention where it was kept. We have found several duplicates of Thwaites CP 3471 in BM, E and K, and have therefore designated a specimen of Thwaites CP 3471 in K, as the lectotype and regard the further duplicates in BM, E, K, and PDA (Veldkamp, personal communication), as isolectotypes.
