 aequantia. ad apicem scapi 2— 3-glomerata vel solitaria, heterogama, 

 disciformia, floribus in ambitu $ °c-seriatis, v paucioribus, omnibus fer- 

 tilibus. Involucrum obovoideum vel obovoideo-campanulatum, bracteis 

 oc-seriatis imbricatis scariosis albis, extimis dorso saepe lanatis, intimis

 nudum. Corollae 2 filiformes, minute 4-dentatae; 9 regulares. tubu- 

 losae, tenues, limbo parum ampliato 5-fido. Antherae apice appendicu-

 subteretes, apice subcapitati. Achaenia oblongo-obovoidea teretiuscula

This pretty Gnaphalium has much resemblance to Amphalis on account 

 of its petaloid bracts. But the disc flowers being all fertile, this must 

 be taken into GnapJialmm. 



2. Ainsliaea elegans Hayata, 1. c, p. 14. 



Herbae laxe pilosae, caulibus erectis 5—6 cm altis simplicibus. Folia 

 omnia radicalia oblanceolata, margene remote aristato-ciliata, acuta, basi 

 attenuata, 15—20 mm longa, 8 mm lata, crassiuscula, pilosa. longe 

 petiolata, petiolis 10 mm longis. Capitula 3— 4-fructus gerentia, secus 

 caulem spicata, sessilia, demum pendula. Involucrum angustum 3—4 mm 

 Iongum, bracteis 3-seriatis, rigidis subpaleaceis aristato-acutis. interioribus 

 elongatis, exterioribus gradatim brevioribus, intimis longissimis 2 1 j 2 mm 



longis. Receptaculum parvum nudum. Corollae Achaenia obo- 



voideo-oblonga subcompressa 5 mm longa, 1 mm in sectione aequantia. 

 10-costata, apice contracta, glabra. Pappi setae 1-seriatae. plumosae,. 

 5 l /2 mm longae. 



Formosa: In monte Morrison, Seizan ad 11707 ped.; leg. S. Naga- 

 sawa, T. Kawakami, et G. Nakahara. Nov. 3, anno 1905. 



Although the specimen is destitute of a flower, it bears fruits from 

 which I determined that this belongs to Ainsliaea. This interesting Ain- 

 sliaea is very like in its stature to the Japanese A. apfculafa. but rather 

 more elegant. It differs mainly by the form of its leaves.
