Washington, DC. radiata について産地別に枝、針葉や球果を多数集めたところ、Cambria の個体群は変種とまではいかないものの他の2つの生息地と違う傾向が見られた。オーストラリアの研究ではこれらの形態・表現型的な違いに加えて遅い成長率、季節ごとの成長に違いが見出されており、おそらく遺伝子的に他の個体群と異なるとされている[2]。近年の研究では各生息地間に僅かな遺伝子的な差異が認められた。そのほとんどは生息地に固有のものだという[3]。, 本種とPinus attenuata やビショップマツ (Pinus muricata) との間で大きく遺伝子移入があるという証拠はないが、雑種の出現は地域的にしか見られない[2]。, 学名Pinus radiata の種小名 radiata は英語のradial(放射状) に由来し、毬果の鱗片の特徴に基づいて名付けられた。英名として一般的な Montrey Pine は本種が広く分布するカリフォルニア州の半島の名前に由来する。他の名前としてはスペイン語風の pino insignis や 種小名 radiata からRadiata pineと呼ばれることも多い。種小名由来の名称は世界的によく使われる。, 日本でもMonterey Pineを直訳したモントレーマツが標準和名として与えられているが、種小名に由来するラジアタマツ、ラジアータマツ、ラジアータパインなどと呼ばれることも多い。ラディアタと表記されることもある。木材の輸入先として大きなニュージーランドやチリを頭に付けたニュージーランドマツやチリーマツという表記も木材・建築業界など、一部で使われているようである[4]。, 基変種、変種ともに自生地は非常に限られている。 基変種はアメリカ合衆国西部カリフォルニア州セントラルコースト (Central coast) の互いに隔絶した3地点、サンマテオ郡 (San Mateo), サンタクルーズ郡 (Santa Cruz), サンルイスオビスポ郡 (San Luis Obispo) で確認されている。この3地点の中で最も北にある場所はAno Nuevoの東側である。同様に真ん中の場所はMonterey や Carmel から約50 km南に行ったところである。一番南の場所は Pico Creek Cambria 地域から約100 km離れている[5]。一番北の場所から一番南の場所までは約200 km離れている。いずれの場所でも海岸に比較的近い場所に生えており、海岸から10 km以上離れた内陸に場所に生えていることはほとんどない。本項では以下、これらカリフォルニアの3地点について近隣の名前をとり、Ano Nuevo(最も北の地点)、Monterey(真ん中の地点)、Cambria(最も南の地点)と記す。, 変種 P. radiata var.

Its leaves are relatively short (8-15 cm long) and usually borne in groups … 更新するに当たり最高の条件は火災の発生である。熱と乾燥によって最大限の数の球果が開き、しかも競合する植生は一時的とはいえ壊滅し、最高の発芽床になる[19]。だから火災の跡地にはとんでもない数の実生が生えてくることがある。火災跡地の森林において、1 haあたり120万本から240万本もの実生が見られたという[20]。, 発芽では 子葉は地上に出てくる(epigeal) 。子葉は5枚から6枚で針葉状。数カ月後には2回目の葉が生えそろうが、3年生になるまでこの2回目の葉以降を出さない。根系は多くの苗で細い直根 (taproot) が発達し、直下の地中へと延びている。実生の成長に最高なのは日差しを遮るものが何もないことである。だから伐採跡地、火災跡地は実生の発芽と速い成長に都合が良い。林地残材 (slash)がたくさんあるところでは実生の密度は下がるが、逆に少しあるぐらいならば乾燥を防ぎ実生の定着に有効である。, 発芽したばかりの実生はとても速く成長する。1年目の成長期を終えた実生は高さが30 - 50 cmに達するのが一般的である。枝の成長は2月には始まり、9月まで続く。競合する針葉樹と比べた場合。地温が低くても生長を始める傾向があるという。土壌中の水分の欠乏が秋の成長を止める。生長の終わりは個体によって、年によって異なる[7]。5年生の苗木は胸高直径6 cm、樹高6 mまで成長する[21]。このころには根を垂直に伸ばすよりも横に伸ばすようになる。, 実生の根は地温15℃のときに最もよく成長する。これは他のマツと比べると約5℃低い。本種の水ポテンシャルは-1.5 MPaまで下がるが、これは気孔の開閉だけでは達成できない数値である。同様の現象がポンデローサマツ (Pinus ponderosa) やコントルタマツ (P. contorta) でも観察されている[22]。, 苗木の伸長生長[注釈 2]は条件の悪い所では15年生ぐらいから低下するが、条件の良い所では50年生ぐらいまで続くという[21]寿命は比較的短い。大きさは80年生から100年生程度で最大になることが多く、150年生を超す個体は少ないという[8]。, Ano Nuevoにおいて混生し、上層を構成する樹種には以下のようなものがある。ベイマツ (Pseudotsuga menzeisii)、セコイア (Sequoia semeperviens), ポンデローサマツ(Pinus ponderosa), P. attenuata, Quercus agrifolia, Arbutus menziesiiなど。, 島嶼部での混生する植生はとても貧弱である。グアダルーペ島においてはナラの一種Quercus tomentella、Eryghea edullsや草本と混生する。セドロス島においてはビショップマツ (Pinus muricata)、Yucca spp. Earle, 2014.01.18].
